The foundation is literally what the house is built on, what keeps the building where it was built, transferring the dead loads and the live loads into the ground. The source of the vast majority of foundation problems is water. Wet soil beneath a foundation can swell or lose strength. Apart from not being able to be used as living or production areas, humid or moist basement floors decrease the commercial life and value of buildings. Mineral waterproofing systems have the advantage of excellent bonding properties of the waterproofing material to mineral substrates, the bond between the individual waterproofing layers is excellent too. The longevity of such systems is ideally the lifetime of the building.
