The waterproofing membrane must be able to withstand cleaning before the concrete is poured, which is an important factor in the selection process. Zemseal® has been extensively tested for cleaning behaviour.
Contamination by soil, cement, leaves, ice, etc. will cause bonding problems with all fresh concrete membranes and should therefore be avoided. However, in many cases this is not possible in the construction process. Only when the contamination has been removed, can the reliability of the entire system and thus permanent water impermeability be guaranteed.
With Zemseal® sub-structure waterproofing system, the types of soiling and cleaning described above do not damage the composite layer, so that backflow safety is still ensured without restriction.
