Types of waterproofing:
- Shallow bed waterproofing layer
- Waterproofing with membrane
- Waterproof concrete tanking
- Bituminous waterproofing coating or membrane tanking
Standard-compliant waterproofing as layer
Shallow bed waterproofing layers allow floor drains in damp and wet rooms to be sealed economically. A special spreadable and fillable sealing compound is applied to the screed; this compound remains flexible when cured, so that no cracks develop. The specifications concerning building waterproofing in accordance with DIN 18534 must be taken into consideration for waterproofing as layer.
Preparing a composite seal
1. Install the drain
Install the drain body (with additional membrane if necessary) and the shallow bed upper section so that the top of the upper section is flush with the screed and completely backfilled.
2. Bond the waterproofing membrane
Remove the temporary cover, clean the flange face, apply installation adhesive and work-in the enclosed waterproofing membrane.
3. Complete the floor construction
Screw on the grating over, including the mating flange. Lay the floor covering and allow it to cure, then grout the grating frame.
Compatibility of construction chemicals and adhesive
For drain technology, we offer drains and channels that include a waterproofing membrane. These must be attached to the drain or channel on site. We have therefore tested various adhesives and confirm that these meet the peeling force requirements of EN 1253; DIN 18534.

Working together with various construction chemical manufacturers, we have also prepared system sheets for composite seals in which it is confirmed that our waterproofing membranes harmonise with the sealing products of the construction chemical manufacturers.
