General notes
- Do not use in case of rain, direct sunlight or great heat.
- At low temperatures, it is recommended that the reverse side of the membrane be heated slightly to achieve a good bond.
- The membrane should be applied at least 15 cm above the water load level.
- It must be protected against damage due to earth backfilling in the excavation pit, for ex. with the drainage mat weber.sys 983 on the external side of basement walls.
- Protective boards are fixed with a Weber bitumen waterproofing thick-layer coating (PMBC – polymer-modified thick bitumen coatings), e.g. weber.tec Superflex 10.
- Protective screeds are to be carried out on separating membrane.
