Basement waterproofing with cold-applied and self-bonding bitumen membranes
Cold-applied and self-bonding bitumen membranes fulfill the standards for waterproofing "ground damp" and "non- pressure water" (DIN 18195 - parts 4 and 5). They are mainly used for the waterproofing of basement walls and concrete slabs in new buildings.
Step by step
-
2. Horizontal and vertical inner angles must be rounded in groove form with the watertight mortar weber.tec 933.
-
3. Apply the solvent-based bitumen primer weber.tec 913 VE in a temperature range from -5°C up to +5°C. Above +5°C use the bitumen primer weber.tec 902.
-
4. Inner angles: cut a piece out from the cold-applied self-bonding bitumen membrane (delivered in rolls) weber.tec 913 (delivered in rolls) in the right size and glue it.
-
10. Movement joints: they are water-proofed with the sealing tape weber.tec Superflex B 240 E (with end T- piece) which is glued with the 2-comp. reactive water-proofing slurry weber.tec Superflex D 2 and covered with the same material on its both sides.
-
16. Use the drainage and protection foil weber.sys 983. Fix it with the metal rail weber sys 983 A at the membrane upper part.
