Planning instructions and technical regulations

The information in this brochure, our application technology consultancy advice, and any other recommenda-tions are based on a large volume of scientific research and many years of experience. Nevertheless, they are only indicative, and designers and fitters remain responsible themselves for checking the products and the installation instructions in combination with all local circumstances, current technical regulations and the current state of the art of the technology, and we accept no liability.

ACO Stormbrixx is a modular infiltration system made from synthetic materials which, on the one hand provides bulk storage, and on the other hand is used to provide bulk percolation of storm water. The installation is carried out totally below ground level. Providing the correct earth covering is an essential part of this (see Page 11). The prerequisites for long-term operation are advance and care-ful planning, correct installation by professionals and where relevant connection to a functioning watercourse, together with regular maintenance/cleaning. The standards for concrete given in the ACO Tiefbau installation details are minimum values. Any special re-quirements which arise from local conditions (resistance to frost, road salt, chemicals, abrasion etc.) need to be taken into account by designers, applying the correct choice of exposure class as defined in DIN EN 206-1 and DIN 1045-2. For the selection and design in particular, but also for the installation of Stormbrixx, the following technical regulations apply in their current versions.

ACO Stormbrixx is a modular infiltration system made from a synthetic material (polypro-pylene) which on the one hand provides bulk storage, and on the other hand is used to provide bulk percolation of storm water.

The basis of the ACO Stormbrixx system are the building blocks which are laid in bonded patterns using an intelligent snap lock system which give the overall system its structu-ral rigidity. ACO Stormbrixx can be installed up to 3 layers deep. Each layer consists of two tiers of basic components.

The ACO Stormbrixx infiltration system (basic elements, side walls and covers) stacks perfectly for ease of transport. The basic elements fit into each other precisely, which reduces the volume to be transported compared to traditional sys-tems. Transport costs and CO2 emissions are substantially reduced.

Logistics and Handling

Ideal stacking reduces transport costsExample: Project A requires a storage volume of 280 m³. Using ACO Stormbrixx the infiltration system components can all be transported on a single vehicle. For other systems up to four vehicles would be needed.

The reduced space required, thanks to basic

elements which stack perfectly, and simple

handling on site both help to reduce logistics

costs.

Transport instructions:The pallets must be transported around the construction site using your own equipment.

Storage instructions/temporary storage:All components of the ACO Stormbrixx system can be stored outdoors. When storing temporarily make sure the ground is flat and solid. To prevent accidents, stack only to a maximum height of 2 pal-lets (32 basic elements, 2.33 m high). For long-term storage at the construction site these double-height pallets need to be se-cured against stormy conditions. The ba-sic elements should, if possible, be stored

in such a way that they are protected from direct sunlight (stored in a shaded area or covered with a light-coloured geotextile, in which case care must be taken that heat is not trapped under the cover). If this is not possible, then they may only be covered over after installation once they have been cooled off (perhaps the fol-lowing morning). Outdoor storage should never exceed one year.

The underlying ground must be strong enough to bear the load and be able to absorb percolated water. If the underlying subsoil is not solid, then the geological structures must be investigated and sui-table measures must be taken. The solid substrate must be prepared so that it is free of stones, even and without gradient. Use your own equipment to remove the excavated soil. The support consists of the surrounding subsoil or any substitute covering added, and must be able to bear

Excavating the Pit and Levelling

a load of EV2 ≥ 45 MN/m², and it must have a cleaning layer (chippings/gravel) of 2/8 grade, approx. 5 cm thick. This cleaning layer must be levelled off. The compacted layer (substrate) must still be permeable after it has been compacted. The quality of this support is critical for the rest of the installation, and will have a significant impact on the stabi-lity and strength of the trench storage components, particularly in the case of multi-layer constructions or those subject

For percolation, the whole of the infiltrati-on block must be wrapped in filter fleece (Geotextile robustness class: GRC 3, weight: 200 g/m², thickness: 1.9 mm). Before starting to lay the basic elements the fleece must be laid over the cleaning layer. The fleece should overlap to the sides sufficiently to allow the entire installation to be wrapped. ACO Storm-brixx are completely surrounded with the filter fleece to prevent the penetration of

Laying the Filter Fleece

fine particles of earth. The fleece needs to be laid diagonally to the main axis of the trench. When measuring the fleece, the following applies: Length of the fleece strips = size of trench + at least 0.50 m overlap. The overlap between any strips which are laid end-to-end should also be at least 0.50 m. Both ends of the geotex-tiles are attached temporarily but securely to the trench embankments and edges. After installing the ACO Stormbrixx com-

The ACO Stormbrixx infiltration system may require an official permit: this must be checked before installing it. During the planning phase, the relevant official and legal requirements, currently applicable technical standards and the DWA (German Association for Water, Wastewater and Waste) work instructions must be taken

to major loads (earth/traffic load). The system must not be installed where it is constantly or intermittently in standing groundwater, stratum water or flood wa-ters. The recommendations of the DWA-A 138 work instructions in this respect must be applied to infiltration systems. These indicate that the distance from the ave-rage highest groundwater level must be at least 1.0 m.

Please note!During construction of the embankments/working space/shoring (DIN 4124) and ex-cavation (DIN 18300), the currently appli-cable standards and accident prevention regulations must be observed.

ponents, the filter fleece will be detached from the sides and edges of the trench and laid over the infiltration system with a minimum of 0.50 m overlap between the strips of fleece. Take care that the fleece is laid snugly against the ACO Storm-brixx system so that no soil can infiltrate between the components and the fleece wrapper.

Please note!Take care that the overlaps are always at least 50 cm, that the fleece surface is completely sealed and that it cannot fall open during in-fill.

Recognised good technical practice, and applicable laws and standards must be respected (such as „Additional technical specifications and guide lines for soil works in road constructions“ (ZTV E-StB), „Directive for standardisation of upper surfaces for road constructions“ (RstO) etc.).

Filling the trench sidesThe stone-free infill material (which must meet DIN 18196) must be compactable and able to absorb percolated water. The coefficient of permeability of the infill ma-terial must at least match the calculated kf-value.Side infilling is to be carried out according to DIN EN 1610, in layers no deeper than

≤ 30 cm each time, up to the upper edge of the trench.

Compact the fill material with a light-weight compactor to a Proctor value of approx. 97%. Avoid any direct contact between the compactor and the plastic components. The insertion of the infill material must not create any problematic distortion, damage or inappropriate loa-ding of the trench system. Care must be taken when infilling and compacting that the overlaps of the geotextile are not dis-turbed and pulled apart, and that the ACO Stormbrixx system is not damaged!

1) Ground cover consisting of cover and upper surface as per RStO regulations2) Please take account of local conditions when defining the frost-free installation depth 3) Variations in cover depths for special cases should be agreed with ACO Tiefbau

Application Technology

CoveringAfter completing the infilling around the sides, a compacted covering of 10 cm of stone-free filler material and a 35 cm thick load-bearing layer of e.g. road metal are placed over the infiltration system to crea-te a flat base for the subsequent struc-ture. Covering the ACO Stormbrixx system must be done in layers, tipping materials from the edge. For this e.g. a light-weight backhoe or wheel loader can be used with a maximum total weight of 15 tonne (4 double wheels). This equipment may only be driven over the site once it is covered by a sufficiently compacted layer with a thickness of ≥ 45 cm, while taking care not to create tracks. For surfaces which will carry traffic the current road construc-tion regulations apply (RStO). During and after the construction phase care must be taken to ensure that no dirt enters the infiltration system.

Please note!Compaction using heavy vibrating rollers is not permitted! Driving construction vehicles directly over the ACO Stormbrixx system is not permitted! Driving heavy construction vehicles directly over the ACO Stormbrixx system is only permitted when there is a compacted covering at least 100 cm thick.

Example: Creating a double block. Two ba-sic elements are placed together so that four pillars with male or female connec-tors are in the middle of the configuration. Two basic elements are turned over and pressed onto the lower basic elements in the opposite direction (1-4).

Installing the Basic Elements

Please note!The company contracted for the installa-tion is responsible for this being carried out correctly. The basic elements must be inspected for damage before installation. Components can be damaged during transport to or around the construction site at low temperatures (below 5 °C). Damaged basic elements, side walls, co-vers, connectors, pipe adaptors and shaft covers must not be installed!

Basic Elements A basic element consists of eight pillars, four equipped with male and four with female connections to lock the two basic elements together. The basic elements are to be set out on the geotextile as shown in the planning/installation dia-gram. Before installing the basic elements we recommend inserting batter boards with the correct dimensions in the trench (to define and fix the outside edges). When installing them, we recommend

putting them in place already connected, as this improves the stability of the entire trench block. They need to be aligned so that there is an inspection space between the pillars. We recommend that each layer of the ACO Stormbrixx system (a layer consists of two basic elements) is organised into a connected layer following the diagram showing the ACO Stormbrixx installation principles.

System Configuration Depending on the requirements of the construction and installation there are a multitude of different configurations of the blocks and sizes of system which can be created.

In its simplest form, it can be a single block of 1,200 × 600 × 610 mm made up of two basic elements one on top of the other. A single ACO Stormbrixx basic element is made up of eight pillars: four with male and four with female connec-tors. To create a complete block, a se-cond basic element is turned upside down and placed on top of the first element. The male and female connectors are lined up, then the two elements are pushed together until all the columns have locked into place. Both elements are designed to remain permanently connected, and cannot be separated without them being damaged.

Linking blocks ACO Stormbrixx makes use of the advan-tages of a linked block structure. Thanks to this feature it is possible to create a layer in a single piece from basic ele-ments which are locked together.

Two basic elements on top of each other make

up one layer (= two tiers) Within a layer the basic elements are placed

head to head.

When constructing the first layer take care

to ensure that four male and four female

connectors are always placed together.

Installing the Lower and Middle Shaft Sections

The lower and middle shaft sections are integrated into the overall system, provide access in up to four directions through the infiltration system and are used for in-spection and maintenance. For multi-layer infiltration systems, the shaft bases are cut out of the intermediate elements and the lower and middle shaft sections are simply stacked on top of each other.(1) All the side surfaces of the lower and middle shaft sections facing the trench system need to be opened up to nominal size

ND/OD 400 using a saw (2). The inner diameter of the shaft lining in the lower and middle shaft sections is 400 mm. If needed, a pipe connection point of SD/OD 110, 160, 200, 250, 315 or 400 can be cut out using a jigsaw along the cutting/sawing marks provided. The lower shaft section is to be placed on the geotextile and fixed to prevent movement in the up-per area of the shaft section (connector).

The outsides of the infiltration system must be covered with the help of the side walls, which are inserted into the ope-nings provided in the basic elements and click into place. The side walls create a perimeter for the entire system offering a clean base surface for the geotextile wrapper. If needed, a pipe connection point of SD/OD 110, 160, 200, 250, 300 or 315 can be cut out along the cutting/sawing marks in the locations provided. The side walls have a predefined saw ma-trix for the connection of plastic pipes of SD/OD 110 to 315, which can be cut out using a jigsaw.

To ensure the geotextile wrapped around the system fits snugly, covers may only be inserted in the top layer of the infiltra-tion block.They prevent the fleece being forced into the necks of the pillars.

Please note!Covers are only built into the top layer of the basic elements, before the fleece is wrapped around them!

Creating the Openings

Tools required/permittedA jigsaw with extra long blades is needed to cut out the openings for the pipe ducts in the side walls, on the top of the basic elements and in the lower and middle shaft sections. Use a drill to get the saw blade inserted when creating the openings in the lower shaft section.

Installing the Connectors/Pipe Adaptors

Cutting out the pipe connection adaptor opening in the side wall

Before installing the basic elements the openings for ventilation in both directions, and for inspection access must be cut out of each basic element.

A permanent marker is used to draw

the openings on the geotextile. Then

the opening is cut out using a Stanley

knife.

16


Inserting the Pipe Connection AdaptorThe pipe adaptors must be used for direct pipe connections to the lower and middle shaft sections, the side walls and to basic elements. After cutting out the openings with a saw and positioning the fleece around the trench, the holes for the adaptors are created in the fleece. The pipe adaptor is held against the fleece and its inside diameter is marked on the

fleece (1). Within the marked circle (2), a cross is cut and the pipe adaptor is pushed together with the fleece into the component until the pipe adaptor‘s flange is lying flush against the component (= sand-proof) (3,4). The pipe connection ad-aptors can be used to connect KG pipes of nominal diameters SD/OD 110, 160, 200, 250, 315 and 400.

Installing the Upper Sections

The upper sections with and without sockets for the inspection and rinsing elements can be rotated around the pipe axis and can be adjusted using their push-fit connection to suit the local gradients in all directions, and their height can be telescoped (+/- 30 mm) and they are watertight to 0.5 bar. The pipe adaptor without a socket is held against the fleece and its inside diameter is marked on the fleece. Within the circle marked, a cross is cut and the upper section (without a socket) is pushed together with the fleece into the opening, creating a sand-proof connection. Before inserting the upper sections, remove the protective film from

the seal and clean the seal. The seals must be coated with a suitable lubricant. The upper section must be inserted to at least the minimum insertion depth!

In the intermediate/upper sections with or without sockets, load spreading and height adjustment of individual compo-nents is ensured using the telescoping principle which applies between the components. Any subsidence in the filled area can be coped with by the tolerance window provided by the telescoping. Load transmission for the shaft cover is achieved by setting the grating in a wet concrete bed.

Access to the Infiltration System The ACO Stormbrixx infiltration system can be accessed from two different points. Through the ACO Stormbrixx upper sections (internal diameter = 339 mm) together with the lower and intermediate shaft sections (internal diameter = 400 mm), which allow passage of the camera and also pressure rinsing. Through the vertical SD/OD 160 access which only supports inspection of the infiltration system.

Ventilation The bi-directional ventilation system is installed after placing the fleece in the trench, and after installing the pipe ad-aptor on the box. After installation of the bi-directional ventilation system the other upper sections are installed. In the upper sections load spreading is ensured thanks to the telescoping which is activated bet-ween the components. Any subsidence in the filled area can be coped with by the tolerance window provided by the tele-scoping.

Vertical Inspection and Rinsing Vent ND/OD 160After laying the fleece and installing the SD/OD 160 pipe connection adaptor on the box, an SD/OD 160 KG pipe made from PP is sat on top of this, up to 7.0 cm below the planned ground surface level. The upper end of the KG pipe is

closed off with a temporary cap until the permanent cover is installed. Thanks to the separation in the construction of the upper section and the KG pipe, the shaft cover transfers the load from passing traffic in full to the neighbouring base courses.

The temporary cover/formwork must protect

the opening throughout the whole of the const-

ruction phase

Shaft cover SA 400 with/out air vents

The cover and frame are made from cast iron. The shaft cover has a maintenance-free, screw-free and traffic-safe catch made from highly wear-resistant plastic (conforms to DIN EN 124 / DIN EN 1229, is stable at extreme temperatures, repels dirt, is self-locking and vandal-proof). Once the cover has been put in place, it can be locked into place by stepping on it vertically on the area sitting over the frame. A concrete seating surrounding the upper section provides the load trans-mission for the shaft cover. A concrete seating C12/15 approx. 20 cm wide is

created all the way around, as defined by DIN EN 206-1, and raised by 2 cm to the highest drain upper section. Use the inser-ted temporary cover/formwork to smooth off the inserted concrete flush. Then remove the temporary cover/formwork, press the frame into the wet cement base to a depth of approx. 2 cm until it is com-pletely seated on the upper shaft section or as required for the final height.

After inserting the frame the dirt bucket compliant with DIN 4052-B low profile needs to be hung in place.

Retention

If retention is required, then the ACO Stormbrixx modular infiltration system must be wrapped in a watertight com-bination of protective fleece/sealing membrane/protective fleece, and welded. The sealing membrane must be protected inside and out against mechanical damage by a protective fleece. The pipe adaptor and the shaft neck must be welded to the sealing membrane. The welding of the

sealing membrane must be carried out by qualified welders and the welded seams must be inspected as per the DVS (Ger-man Welding Association) guidelines. The water-tightness of the seams must be pro-ven and inspection reports to this effect must be presented to the customer. This work must be carried out by a specialist company with certified plastic welding equipment.

The ACO drainage channel collects the surface water and channels it via the outlet shaft into the ACO sedimentation shaft where the solids are separated from the rainwater. Via the outflow gulley the rainwater is first collected in the ACO Stormbrixx infiltration system and then gradually released into the ground.

Practical example of the ACO Tiefbau System Chain

The ACO yard drain collects the surface water and feeds it directly into the ACO Stormbrixx infiltration system where it gradually seeps out.

Quality Assurance during and after Construction Work

The suitability of the construction materi-als to be supplied by the contractor must be demonstrated to the customer.

Goods receipt inspection of the mate-rials used e.g. construction materials (ACO system, fleece, infill material ...) for

labelling damage completeness

Measured load-bearing ability and even-ness of the supporting surface (proof to be supplied)

Fleece on supports (no folds, correct overlaps) visual inspection and measu-rements

Layout plan followed, visual confirma-tion

Fleece wrapping/accessory parts (inter-mediate acceptance prior to infilling), visual inspection

Insertion of infill material (proof of com-paction), measurements

Final acceptance (documentation of the processes, infiltration and retention, to be kept separate, for mass retention the water-tightness must be checked, and the inspection records for the seams)

Possibly, control inspection by the customer. Visual inspection by means of TV passage (with record) through the installation

For retention please also see Page 18

Operation of the system The infiltration system may only be made functional after acceptance of the con-struction. Penetration by roots into the infiltration system must be avoided by following a suitable planting plan. We re-commend that where trees either already exist or are to be planted, that a minimum distance of half the potential crown dia-meter be maintained (in addition to using root protection foils).

Please note!For each application site you need to take into account the load represented by the soil and traffic. If necessary, the ACO Tiefbau application technology can advise what is required, based on the details of the proposed construction. Unusual construction conditions will require individual inspection and this should be arranged with ACO Tiefbau application technology. The approval of these unusual construction conditions must be given by the construction company and/or the building supervisor/planner.
