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“


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

Recognizing the

underground permeability

bindig not bindig

loamy/ claylike sandy/ rocky

K < 10-4

m/s K > 10-4

m/s

K - factor of permeability


Water proofing with bituminous

lengths

water proofing with KSK

water proofing with KMB:

– at least 3 mm thick layer

– 2 applications

Kinds of stresses

DIN 18 195 - 6 „water with pressure


proofing against temporarily

existing external water pressure or

constantly pressing waters

(groundwaters)

Underground

lengths

water proofing KMB:

– at least 4 mm thick layer

– 2 applications

– layer of reinforcement (fibreglass)

„constantly pressing waters“


lengths

nothing else allowed by the norm

industry (PCI) guarantees with

certain KMB products !

DIN 18 195 - 4 „ground waters“





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


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








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


– 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


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


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


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

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)
