Below ground waterproofing is the first and a necessary step before developing a construction project. It is critical to tackle from the beginning threats as unequal static forces, water ingress, aggressive chemicals, gas penetration, external mechanical pressures, and temperature variations. Especially today, more and more building projects require the development of under-ground areas and basements that can be found in large building sites like modern hotels, residential buildings, in large car parks or stadiums.
