Design and construction of components impermeable to water*

Fundamentals of sealing technology according to WU (water impermeable) guidelinesIn order to prevent ingress of water into structures, water im-permeable reinforced steel struc-tures, so-called "white tanks", have been fabricated for over 30 years. Thanks to these long years of practice and experience,

this method of construction rep-resents an economical way of stopping the ingress of water. Furthermore, the WU guidelines represent the generally recog-nized current technical standard with regard to the "white tank".

The watertightness of a structure is characterised by the limitation of water ingress through con-crete, construction joints and pre-crack dummy sections, mounting parts and cracks.

Construction method with de-creased force stressing:Force stressing on concrete that can lead to water-channeling cracks is reduced by suitable constructional, concrete-related technical and design measures.As part of this are, e.g. level un-dersides on floor slabs with a layer of film, use of concrete re-ceptors with low development of hydration and heating and extended after-treatment meas-ures.

Method of construction with lim-ited crack width:The method of construction with crack width limitation applies as the second approach to the solu-tion. In this case, an increased re-inforcement content of the con-crete construction controls, orlimits, the crack width.

Method of construction with subsequent sealing:In the case of the third method of construction, no special measures are introduced prior to the con-struction and formation of the cracks channelling the water are accepted. Later these are tightly sealed in accordance withthe relevant guidelines. However, this method of construction may not be used for residential build-ings.

Design basics

*Source: "Bulletin 555 - Comments on the DAfStb guidelines on water impermeable concrete structures" from the German Committee for Reinforced Concrete (DAfStb)

� Sealed construction of all joints

�Meeting high requirements of the concrete

�Maintaining the minimum thickness for structural ele-ments

� Crack limitation in structural components

�Maintaining a minimum height of the pressure zone

�Methodical arrangement and design of construction joints or sections of the pre-crack dum-mies if crack formation is ex-pected

This means:

5Systematic sealing



Design objectivesA design of the arrangements must be carried out and the de-fined designs documented. For designs in accordance with WU guidelines, close collaboration between the different design areas is necessary. The following are the participants:

� Object designer/architect

� Geo-technician (if required)

� Bearing structure designer/WU designer

� Successful tenderer (work scheduling)

� In agreement with the con-struction participants depend-ing on the complexity of the project: concrete

� technologist, construction physicist, building engineering designer.

The function and required utili-sation of the structure, together with the regulations regarding fitness for purpose must be de-fined and documented. The following points must be clarified:

� Impact: the stress on the struc-ture as a result of standing wa-ter or soil humidity

� Utilisation: which requirements need to be met by the structure in regard to impermeability to water

The result of the first two design stages form the basis for further design measures.The impermeability to water of a structural element is determined by several factors.

The following points are to be accounted for in detail, both in-dividually and in their combined effect:

� Selection of the concrete

� Dimensions of the structural components and reinforce-ment channels

� Avoidance or sealing of cracks or limitation of the crack width

� Planning of all joints and pen-etrations

� Planning of construction se-quence, concreting sections, construction joints and sections of the pre-crack dummies

�Where necessary, account must be taken of aggressive water and soil.

The concreting work, the af-ter-treatment and the structure monitoring must be executed in accordance with DIN 1045-3.

Defining the WU guidelines


Utilisation class A Utilisation class B

■ No water passage in flowing form ■ No points of humidity on the surface ■ No cracks and joints channelling

water

■ Areas of humidity permissible ■ From temporary up to self-healing

water-carrying cracks permitted ■ No gathering of water on the

surface

Application examples:Residential building, storerooms with high-grade utilisation

Application examples:Underground car parks, installation and supply shafts, storerooms with low-level requirements

The WU guidelines determine and define the specifications for

concrete structures impermeable to water. These are regulated

in relationship to the stress and utilisation classes.

Stress classThere are two stress classes. They are differentiated by whether the flow of water is directly on the structure or the concern is only with soil humidity or, as the case may be, with seepage water.

� Stress class 1: for pressurised and non-pressurised water as well as intermittently trapped seepage water

� Stress class 2: for soil humidity and non-trapped seepage wa-ter

Utilisation classThe WU guidelines differentiate between two utilisation class-es. They are dependent on the

function of the structure and the requirements on the thickness, and must be defined accordingly.

In the selection of a suitable con-crete it should be noted that, in addition to the requirements arising from the exposure class-es from DIN 1045 pertaining to the structural component, the requirements on a concrete with high resistance to water ingress must also be satisfied.

A sufficient workability can be guaranteed by the consistency class F3 or softer. In the design of WU structural components in the minimum component thickness-es, a water/cement ratio of ≤ 0.55 and for walls, in addition, a larg-est particle size of ≤ 16 mm, must be used for stress class 1.

For a head of more than 1.0 m (e.g. for walls) an attachment mixture (largest particle ≤ 8 mm) must be used in the foot area at a height of ≥ 300 mm, in order to ensure a zero defect installation of the concrete.

Requirements on the concrete

Structural component thickness

From many years of experience with concrete structural cast in-situ and pre-cast components, the following minimum thicknesses for the structural components are specified in the WU guidelines:

The minimum thickness and construction of the structural components must be selected such that the concrete structur-al components can be concret-ed technically correctly whilst adhering to the concrete cov-er, the required reinforcement location, joint sealing and the mounting components. In ad-dition to all the other required features, it must also be possible to fulfil the support and sealingfunction.

Over and above the minimum dimensions, the following apply to the clearance dimension bW,i between the reinforcement lay-ers (for in-situ concrete) or for the spacing of the interior sur-faces of the form (for element walls) in order to ensure a tech-nically correct installation of the concrete:

� for a largest particle of 8 mm bW,i ≥ 120 mm



If component thicknesses result from this that are larger than the minimum dimension in the table above, these become the standard.

7Systematic sealing



ProofProof of impermeability to water is an additional proof of fitness for purpose for DIN 1045-1, Clause 5.4.1, Section 2.

Limiting the crack widthFor bending cracks resulting from stress and forces it must be proved for utilisation class A, stress class 1, that the pressure zone height (x) satisfies the con-dition x ≥ 30 mm and ≥ 1.5 · Dmax, whereby Dmax is the largest diam-eter of the aggregate. If there is an acceptable temporary ingress of water through separating cracks for stress class 1, the cal-culated widths of the separating cracks in relationship to the pres-sure gradients are to be limited according to the table.

Pressure gradient hw/hb*

permissible crack width w [mm]

(calculated value)

10 0,20

> 10 bis ≤ 15 0,15

> 15 bis ≤ 25 0,10

* hw = pressure head of the water in m hb = component thickness in m

If the table values are adhered to, it can be assumed that the in-itial water ingress will be great-ly reduced with time through self-healing of the cracks. Hu-midity spots on the surface of the structural component cannot, however, be ruled out with cer-tainty even at a later time.For stress class 2, the permissiblecrack width for walls w ≤ 0.20 mmapplies to the calculated value, for floor slabs proceed according to DIN 1045-1, Clause 11.2.1.

Proof for utilisation class AThe required proofs conform with the selected design funda-mentals of utilisation class A. For this, verification is needed that no separating cracks occur in the concrete as a result of force. The exceptions here are the planned, sealed joints. To this can be counted the pre-crack dummy, construction and expansion joints through the ar-rangement of which, at specified spacings, the reduction in the force on the structural compo-nents follows.

The limitation of the incident crack widths results from the de-sign of the pre-crack dummy and construction joints and/or the ar-rangement of the reinforcement.

Example of utilisation class A

Proof for utilisation class B The required proofs conform with the selected design fundamen-tals of utilisation class B. Their requirements are met through a limitation of the separating crack widths with the assumption that the cracks are self-healing. The limitation of the incident crack width results from the design of the pre-crack dummy and con-struction joints and/or the ar-rangement of the reinforcement.

PENTAFLEX®


Reinforcement andconstructional regulations

The configuration of the rein-forcement in the structural com-ponents must be designed such that it is possible to have a fault-less insertion and compaction of the fresh concrete. WU compo-nents of stress class 1 should be fabricated with a double-sided mat reinforcement composed of longitudinal and transverse re-inforcement. The exception to this are prefabrications of stress class 2.

The construction joints must be defined by the designer and rep-resented in a blueprint.In accordance with the defined stress and utilisation class, all joints in WU construction compo-nents must be permanently guar-anteed by a complete sealing sys-tem that is impermeable to water and uniform.

Pre-crack dummy sections are caused by sufficient weakening of the concrete section (at least 1/3 of the structural component thickness) and must be sealed for the smallest, but nevertheless appreciable, movements. Special pre-crack dummy elements guar-antee both requirements and are thus suitable for structures of uti-lisation class A.Element wall splices are to be de-signed as pre-crack dummy sec-tions.

Joint sealing

Only products holding a proof of applicability may be used for sealing joints in WU structural components. A general building authority approval (abP) provides this proof for non-standardised products.

All of the joint seals that con-nect with the concrete must be precisely placed according to the design, connected to the splices and forcefully and permanently secured in position prior to the concreting operation.

Coated laminations

A joint sealing system must con-stitute a closed system and have a sealed contact to all of the con-nection and crossing points.

In the case of joint sealing for pre-crack dummy sections it must be ensured that the sealing effect ismaintained in the event of crack formation and the associated widening of the joint.

An integral joint laminate does not absorb any kind of shear force. The lamination must demonstrate sufficient elasticity to survive any possible deformation without damage. This will prevent any temporary seepage of water.

For coated laminated joints, con-siderably less anchoring depth in the concrete is required, as is the case, for example, for uncoated joint laminations. The necessary minimum anchoring depth can be taken from the proof of fitness for purpose (abP).

Design and construction of components impermeable to water

Extract from the practical instructions for the basic blueprint "Method of construction with reduced force loading":

Construction system for floor slabs At least one layer of PE film must be laid on a sub-base under-neath the floor slab. The mini-mum thickness of the floor slab is based on the WU guidelines. For pressurised water this is 250 mm.The concrete cover of the up-per layer of reinforcement is the responsibility of the build-ing contractor and must be pre-cisely complied with. This is a prerequisite for the pressurised-watertight installation of the PENTAFLEX® joint system.From experience the minimum degree of reinforcement of the floor slab is at least approx. 0.15% of the concrete section on both sides. If the proof of stability pro-vides for a higher reinforcement content, this must be installed. This minimum reinforcement is to be arranged crosswise in two layers.Re-entrant corners must be se-cured by a diagonal reinforce-ment (e.g. 3 pieces Ø 12 above and below). The required wall connection reinforcement, e.g. Ø 8 nails with predetermined spacing for prior anchorage. Oth-erwise compliance is required with the reinforcement guide-lines of DIN 1045-1.

ConcretingThe grades of concrete in accord-ance with DIN 1045 II/EN206 must be adjusted to take account of the required exposure class and the special requirements of the building provisions.If the consistency for processing the concrete on the building site is finally discontinued, a water-re-ducing admixture (FM) must be used. At the same time it must be guaranteed that any concrete additives that have already been added are compatible with the water-reducing admixture (FM). The maximum amount of addi-tive according to the manufac-turer’s instructions must not be exceeded.

When concreting the floor slab, make sure that the concrete is in-troduced and compacted fresh on fresh. In the area of the PENTAF-LEX® elements care is required when inserting the concrete. If the floor slab is thicker than 400 mm, the concrete must be insert-ed and compacted in two layers (fresh on fresh). To facilitate af-ter- treatment, the concrete slab must always be covered with film and must be protected from strong solar radiation with water and from frost with heat protec-tion mats.

PENTAFLEX®

Design and construction of components impermeable to water

Extract from the practical instructions for the basic blueprint "Method of construction with reduced force loading":

Provisions when concreting wall elementsDue to the small cross section of the core concrete, special care is required when concreting the core of the element wall.

Initially it is essential to check the filling area of the element walls for loose assembly elements, im-purities and contamination of the joint elements. Where nec-essary these must be removed. The surfaces of the concrete form that face the core must be wet-ted before concreting.

The corner and straight splices

of the wall elements must be se-cured against the concrete pres-sure using the specified form-work pressure retaining elements and supported with angled brac-es.

The concrete is introduced in layers of maximum 800 mm and compacted in accordance with the formula: diameter of the vibratory con-crete poker x 10 = efficiency.

The vibratory concrete poker is inserted quickly and slowly with-

drawn again. The poker is insert-ed far enough so that the layers bond with one another (nee-dling). The layers must be intro-duced fresh on fresh.

Up to a height of at least 300 mm, a concrete mix should be used with a largest particle size not exceeding 8 mm. This ensures a zero defect attachment to the base of the wall.For windows and other recesses the concrete is filled on one side until it comes smoothly out on the other side.

PENTAFLEX KB® Plus – added functionality

The product

The combination of seal and foundation earth – double securi-ty in one work step: a seal which resists pressurised water and also acts as a foundation earth.The product benefits of the tried-and-tested PENTAFLEX KB® joint plate remain the same: water pressure tested up to 5.0 bar, ap-proved up to a water pressure of 2.0 bar.In addition to sealing, the ele-ment also performs the function of a conventional foundation earth. Tests, occasionally up to the highest lightning current class (class H), have been success-fully carried out at the high-volt-age laboratory of the University of the German Federal Armed Forces in Munich. This means that the PENTAFLEX KB® Plus product can be used universally as a foun-dation earth.

Features

� Twice as reliable due to the combination of tried-and-test-ed PENTAFLEX® quality seal and foundation earth

� Cost-effective due to time and material savings: two work steps rolled into one

�More efficient stock manage- ment as the conventional foun-dation earth in the form of rolled steel or rod steel is no longer required

� The benefits of the product PENTAFLEX KB® remain the same

� The PENTAFLEX® FTS, OBS, ABS connection elements and PENTAFLEX KB® corner can be connected in any situation.

Application area

The foundation earth is an in-tegral part of the electrical ser-vices of the building. It is part of the equipotential bonding of the building services and, if nec-essary, an element of a lighting protection system.The foundation earth normally consists of a closed ring-shaped steel band. The steel band is em-bedded in the concrete of the foundation and the walls it sup-ports. The PENTAFLEX KB® Plus prod-uct therefore has two functions: when installed as ring-shaped sheet steel element in the foun-dation, it acts as a seal and also as a foundation earth.

PENTAFLEX KB® PlusJoint plate and foundation earth



According to the current rules and standards, the foundation earth must be connected to the reinforcement every two metres.In addition to the envisaged con-nection with the reinforcement, it is also possible to connect com-mercially-available connecting lugs or fixed earthing terminals. The main earthing rail, lightning conductor or extension of the earthing system such as an ex-terior ring earth connection or

earth rod can then be connected at these points. This means that PENTAFLEX KB® Plus can be used universally.By connecting an equipotential bonding strip, the PENTAFLEX KB® Plus product can function as an equipotential bonding ring con-ductor as well as a foundation earth.

As a fundamental principle and in accordance with DIN 18014, a ring earth electrode is required in addition to a foundation earth when constructing a white tank. This ring earth electrode must be installed outside the white tank. Commercially-available products can be used for this. The ring

earth electrode must be connect-ed to the foundation earth using commercially-available products. The connection is established using commercially-available clamps via the PENTAFLEX® Plus connector.When establishing the connec-tion between the ring earth

Expansion joints must be bridged by water-impermeable electrical-ly-conductive means. These joints are sealed using the tried-and-tested PENTAFLEX® DFA expan-sion joint connector. The expan-sion joint connector is connected to the PENTAFLEX KB® Plus base element. The overlapping areas are fixed

These commercially-availa-ble expansion strips are normally connected to commercially-availa-ble fixed earthing terminals. An electrically-conductive con-nection is then established via

the PENTAFLEX® Plus connector between the fixed earthing ter-minals and the PENTAFLEX® Plus clamps. The clamps and connec-tors must be assembled in accord-ance with the installation instruc-tions. A schematic representation of the bridging of an expansion joint is shown below:

electrode and foundation earth, make sure that leak-tightness of the white tank can still be guar-anteed. The connection must therefore be above the highest ground-water level or routed inside the building using water-tight wall lead-throughs.




The PENTAFLEX® expansion joint connector DFA is a clamping de-vice which connects PENTAFLEX® elements to all types of expan-sion joint strips. The expansion joint connector is attached to the expansion joint strip at the end piece of the PENTAFLEX® element via a screw-type clamping device.

AssemblyThe connection of the DFA to the expansion joint strip is made us-ing a screw-type clamp connector. Holes must be made in the expan-sion joint strip so that the DFA screws can be pushed through the expansion joint strip. The required installation depth in the floor slab must be observed. The rubber swell strip is inserted between the expansion joint con-nector and expansion joint strip. The clamping device is completed by the press-on flange and held down by butterfly screws.The expansion joint connec-tor DFA is connected to the PENTAFLEX KB® in a similar man-ner to that described in the instal-lation instructions on page 14.

PENTAFLEX® ABSInstallation instructions floor/floor, ceiling/ceiling

1. Insert a suitable spacer, nominal size c, on the sub-base/formwork at the location where the construction joint should be (lev-el of the expanded metal). Install the ABS el-ements on the lower reinforcement layer. The direction of installation should be such that the formwork girder faces the side of the first concrete section. Tie wire is used to attach it to the lower reinforcement. Alternatively, the ele-ment can also be welded to the reinforcement.

2. Extend the ABS elements by means of butt jointing. Peel the film on one side, at the top and bottom, off the PENTAFLEX KB® element and push as far as it will go into the formwork. The joint plates must overlap by 50 mm, be pressed firmly together and secured with a cross clip. The abutting end must be heated if the tem-perature is below +5° C.

3. Lay the upper reinforcement and set a stop end to the upper concrete layer. Attach the ABS element to the upper reinforce-ment using tie wire. Alternatively, the element can also be welded to the reinforcement.

4. Before concreting the second section, remove the protective film on the top and bottom of the steel joint strip.

PENTAFLEX® OBSInstallation instructions

1. Remove all films from the PENTAFLEX® OBS ele-ments.

2. Insert a suitable stop end, nominal size c, in the formwork exactly at the location where the pre-break should be (level of the assembly sheet steel).

3. Install the OBS element in the wall formwork between the outer and inner reinforcement layers. Tie wire is used to attach it. This is guid-ed through the holes provided in the assembly sheet steel and fixed to the reinforcement. The position of the OBS element must be fixed so that the assembly sheet steel is immovable at the level of the planned pre-break point; this means that the sealing plane will be exactly parallel with the surface of the formwork on the axis of the floor/wall joint seal.

4. The OBS element is then attached to the PENTAFLEX KB® by overlapping at least 50 mm and pressing the coated sheet steel firmly to-gether. At temperatures below +5°C, the abut-ting surfaces must be heated.


for better solutionsPENTAFLEX® OBSInstallation instructions

5. Each connection location must be secured with two cross clips.

6. Before the wall formwork is closed, a suitable formwork, e.g. a trapezoidal strip must be attached true to size in the axis of the OBS element assembly sheet steel.

7. Care is required when concreting to ensure that the OBS element is not exposed to concrete pressure on one side. Always keep the pouring height equal on both sides.

8. Joints and connections must be fabricated and secured using the connections specified in points 4/5.

PENTAFLEX® Thermo-TranswandTechnical information

GeneralIn recent years, double element walls have been systematically developed. Nowadays, double walls with internal thermal insu-lation are no longer the excep-tion. These thermal walls are be-ing used both in residential and industrial buildings.

Two points must be clarified when using PENTAFLEX® pipe lead-throughs in thermal walls:

� Are they to be installed in wa-ter-impermeable structural ele-ments such as thermal walls for cellars or

� Are they to be installed in thermal walls for multi-storey buildings or halls that do not have to comply with the WU guidelines?

Thermal wall structural compo-nent thicknessThe structural component thick-ness is based on:

� The thickness of the core con-crete

� The thickness of the insulation

� The thicknesses of the form-work

PENTAFLEX® pipe lead-throughs are designed for water-imperme-able structural components. According to the WU guidelines, a minimum core concrete thick-ness of 120 mm applies with a maximum grain size of 8 mm for element walls of stress class 1. This ensures that the seal on the inside will be of sufficient quality.

As the maximum grain size in-creases, the minimum clearance bW,i between the reinforcement layers (for in-situ concrete) or clearance between the internal surfaces of the formwork (for el-ement walls) increases in order to ensure technically correct installa-tion of the concrete.The requirements to be met by the component thicknesses are shown on page 4.

The manufacturers of thermal walls offer insulation for integra-tion in double walls with thick-nesses of 80 – 120 mm.

PENTAFLEX®

Glossary*

Attachment mixture: comprises a concrete with a maximum aggregate particle size of 8 mm that can if required be used at the attachment area between walls and floor slabs or ceilings.

Stress class: defines the type of stress due to mois-ture or water a structure or structural compo-nent can withstand.

Soil humidity: amount of capillary-bound water in the soil.

Pressurised water: water that applies hydrostatic pressure (also time-limited, e.g. retained seep-age water) on one side of a structural compo-nent. A differentiation is made in the following case:

Occasional retention of seepage water: water that flows off freely under the influence of grav-ity and can accumulate from time to time on soil layers with low permeability. This type of stress occurs when the embedment depth of the struc-ture is less than 3 m in soil of low permeability without drainage in accordance with DIN 4095, when the base of the structure is at least 300 mm above the design flood level and only backwater is anticipated due to the type of soil and terrain.

Ground water, high water, strata water: any kind of pressurised water that are not temporar-ily retained seepage water.

Penetration: occurs when a structural component penetrates a water-impermeable structure, e.g. pipes, discharge, cable lead-through, formwork ties or similar.

Element wall: structural wall elements comprising two interconnected prefabricated slabs supple-mented by a core of in-situ concrete.

Pre-fabricated element wall: wall constructed from single-skin prefabricated wall elements.

Joint: interface between two structural components or concreted sections. A differentiation is made in the following case:

Construction joint: interface which is in direct contact with two bonded concreted sections. Construction joints without joint sealing are re-garded as separating cracks.

Expansion joint: intermediate space between two structural components or concreted sections that permits different types of deformation.

Butt joint: joint between two hardened concrete structural components with negligible relative deformation of the adjacent components (in-situ concrete/prefabricated component; prefabricat-ed component/prefabricated component).

Joint seal: built-in components and building mate-rials for sealing a joint or shinkage crack control section to prevent the ingress of water.

Non-pressurised water: water in fluid droplet form that applies no, or negligible, hydrostatic pres-sure (100 mm water column) to components.

Non-retained seepage water: water that seeps into the soil and can seep through to the free ground water level in the case of highly permeable soil without being retained or, in the case of less per-meable soil, can be drained off in front of the structural component by a permanently func-tional drain in accordance with DIN 4095.

Utilisation class: defines the requirements for the internal environment and humidity conditions for the surface of the components based on the planned use of the structure or structural com-ponent.

Crack: break in the concrete structure. A differenti-ation is made in the following case:

Bending crack: crack with greater depth which does not run through the entire thickness of the component and separates the component thick-ness into a cracked (tensile zone) and uncracked area (pressure zone).

Separating crack: a crack which runs through the entire thickness of the component.

"Self-healing" of cracks: time-based reduction of water ingress by separating cracks depending on the crack width and fluid pressure gradient.

Shrinkage crack control section ("dummy joint"): weakness that is designed into the component cross-section, also of the reinforcement crossing at this cross-section, in order to bring about a break in a specific location. Shrinkage crack con-trol sections without joint sealing are considered as separating cracks.

Water passage: transport of moisture in liquid form through the component to the surface.

Water impermeability: qualitative or quantitative statement on extent to which water can pass through concrete, joints, built-in components and cracks.

Force: stress that occurs as a result of preventing load-independent deformation, e.g. due to the effects of changes in temperature or shrinkage.
