Internal basement waterproofing

The basement is waterproofed from the inside without excavating the soil around the building. This means that the basement is permanently waterproofed without the necessity to do any sort of earthwork. This type of waterproofing can be done even when the
wall has active leakages. The waterproofing against pressurised water is achieved with a special coating system. Furthermore a diffusion-open restoration plaster is applied after successful waterproofing.
