Protection of basement waterproofing

Waterproofing products of building structures must do a lot. Watertightness, long-life expectancy, flexibility, and resistance to weather conditions – all these requirements must be fulfilled by these products. Waterproofing products on earth-contacting building structures must perform more – they must withstand the earth pressure. Not only the surface pressure, but also the impact pressure of sharp stones etc. Waterproofing layers must be protected against such loads, otherwise they will be hurt and be leaking. For the protection and drainage of waterproofed basement walls, combined drainage and/or protection panels can easily be bonded e.g. with weber.tec Superflex 10 (2-comp. lightweight bitumen waterproofing thick coating) after the waterproofing has dried. As alternative: we recommend the use of the drainage mat weber.sys 983. All protective layers (hard foam boards, drainage foils, protection foils) are first installed after full drying of the waterproofing layers.

Simple & safe to the goal

  1. 1. Glue the protection boards dotwise with a PMBC on their backside in case of ground damp/non-pressure water (W1.-E) or full-surface in case of pressure water (W2.1-E).

  2. 2. Lay the protection boards tightly butt to each other. In case of fleece-covered foils pay attention that the fleece sides are properly overlapped.

  3. 3. The protection of waterproofing is done all over the basement walls. Install the boards from the basement bottom upwards. They must lay firmly on the protected forepart of the concrete slab.

  4. 4. Cut the drainage mat weber.sys 983 according to the requested dimensions and install in vertical direction. The gliding part is placed face to the wall and the fleece-backside face to the earth. The metal profile metal rail weber.sys 983 A ensures a secure hold and a clean finish at the top.

  5. 5. Carefully let overlap the fleece sides. At the bottom place the foil over the concrete slab forepart to the extent that a professional connection with the horizontal drainage can be done.

  6. 6. Fix weber.sys 983 over the upper level of the waterproofing layer with the metal rail weber.sys 983 A. Afterwards, the excavation can be filled by careful backfilling of the soil in several layers and compacting.

  7. 7. Cross-section of the bottom part of the foundation and drawing of the connection with the circular drainage pipe.
