WATERPROOFING ACCORDING TO DIN 18534
DIN 18534 distinguishes between three diff erent types of
liquid waterproofing that may be used in a composite:
Polymer dispersions, crack-bridging mineral waterproof-
ing slurries and reactive resins. In addition, the standard
diff erentiates the application of liquid waterproofing
materials depending on water exposure classes and crack
classes.
In the following, the application in relation to the water
exposure classes is discussed. (The classification for crack
classes is set out in the standard).
Overview of the approved liquid sealants in relation to the
water exposure classes (in the private sector W0-I to W2-I)
and the application on walls and floor:
ATTENTION: The minimum dry film thickness
must be 0.5 millimeters for polymer sealants
and 2.0 millimeters for cementitious sealing
slurries. This must be ensured with a consump-
tion quantity control or a wet film thickness
control.
TIP: Since the manufacturer has to specify
the required application quantity per square
meter, the calculation via the consumption is
the simpler variant.
