norms
DIN 18 195
– water proofing of structures
– edition august 2000
– stresses ruled in pt 4-6
Kinds of stresses
DIN 18 195 - 4 „ground humidity“
DIN 18 195 - 6 „water with pressure“
DIN 18 195 - 5 „horizontal parts“
DIN 18 195 - 4 „ground humidity“
How to calculate and realize water
proofing against the stress of water
existing in sandy/ rocky grounds or
water passing the structure without
chance to build up pressure
Underground not
binding, very good
permeability
Underground
binding, little
premeability
Draining layer
Draining tube

underground permeability

bindig not bindig
loamy/ claylike sandy/ rocky
K < 10-4

m/s
K - factor of permeability
DIN 18 195 - 4 „ground humidity“
Water proofing with bituminous
lengths
water proofing with KSK
water proofing with KMB:
– at least 3 mm thick layer
– 2 applications
Kinds of stresses
Vorschriften
DIN 18 195 - 4 „ground humidity“
DIN 18 195 - 6 „water with pressure“
DIN 18 195 - 5 „horizontal parts“
DIN 18 195 - 6 „water with pressure
How to calculate and realize water
proofing against temporarily
existing external water pressure or
constantly pressing waters
(groundwaters)
Underground
binding, little
permeability, no
draining system
3 m maximal
depth of the
constructional pit
Relevant water-level
DIN 18 195 - 6
„temporarily pressing waters“
Water proofing with bituminous
lengths
water proofing KMB:
– at least 4 mm thick layer
– 2 applications
– layer of reinforcement (fibreglass)
DIN 18 195 - 6
„constantly pressing waters“
Water proofing with bituminous
lengths
nothing else allowed by the norm
industry (PCI) guarantees with
certain KMB products !

Vorschriften
DIN 18 195 - 4 „ground waters“
DIN 18 195 - 6 „water with pressure“
DIN 18 195 - 5 „horizontal parts“
DIN 18 195 - 5 „horizontal parts“
How to calculate and realize water
proofing underground roof-
constructions and horizontal parts
in bathrooms and other rooms,
exposed to waters without pressure
will be dealt with tomorrow!
Material
KMB
– polymer-modified bituminous coating
after filming
– water proof
– long lasting
– able to cover tears of the underground
Material
Bituminous emulsion
– small parts of bitumina in water
– emulgator
– additives (polymers, polystyrol-balls etc.)
1- component KMB
Have to dry out
easy to deal with
no mixing
got advantages with pumping
slow filming
Where to use:
outside
water proofing basement walls
water without pressure/ with pressure
Produkteigenschaften:
water proof, long lasting
flexible
good adhesion at undergrounds
Technische Daten:
polymer-bitumina-emulsion,
with polysytrol- balls
filming by drying
1 - 5 mm thick layers
2- component KMB
Filming by chemical process
has to be mixed
„Ankerrührer“ as mixing device
accelerated filming
faster progress in work
Anwendungsbereiche:
outside
water proofing basements
water with/ without pressure
Produkteigenschaften:
water proof, long lasting
flexible
good adhesion to undergrounds
Technische Daten:
KMB with polystyrol- balls, cementitious 2nd
component
2 components
resistent against rain in about 4 1/2 h*
* bei 23°C / 50% Luftfeuchtigkeit
Water proofing of structures
Surroundigs / statistics
kinds of stresses, norms
preparation of the surface
application of bituminous products
protecting and testing
alternative measurements (KSK)
Preparation of the surface
No anti- adhesives
not wet, just humid
even, max. 5 mm tolerance
no sharp edges/ corners
No anti- adhesives
Anti- adhesives are e.g.
– dust, dirt
– seperating oils, tar coatings
– layers of poor adhesive stength
have to be blasted away
Even underground
Max. tolerance 5 mm
– corners have to be broken
– burrs habe to be hit off
– holes have to be filled
– perhaps a thin plastering makes sense
– rounding out inner corners

testing
Thickness of the layer
filming state
documentation
testing
Thickness of the layer
– use notched trowel for application
– check thickness 20 times each 100 m²
– check thickness in fresh applied material
and „repair“ the „check-hole“
– never applie more the twice the minimal
amount
filming state
documentation
testing
Thickness of the layer
filming state
– wedge- shaped material appliance
– thickness ca. 3 - 10 mm
– put it to the place worst for filming
– check the filming state
documentation
testing
Thickness of the layer
filming state
documentation
– duty with 18195 - 6, good anyway
– control of layer-thickness with date, place
and result
– filming state with date, weather and result
protecting
Protection against physical damage
has to be made sure
gliding down with settlement of the
material filled into the construction
pit must be possible
Where to use:
outside walls
basements
protection and draining-system for
PCI- Pecimor
Produkteigenschaften:
resistent to ground pressure to 3 m depth
easy to deal with (special corner element)
effective protection for the KMB
Technical information:
polystyrolfoam with 2 fleeces
stick to the underground with 2 comp- KMB
filling the construction pit in 1-2 days*
* with sticking with several points

alternative measurements (KSK)
Alternative measurements KSK
KSK - length, selfsticking without
local heating
alternative for fast advance
(filling the pit immediately after water
proofing)
alternative for low temperature
(down to -5 °C)
