Foundations (Below ground external) Waterproofing
Home > Systems > Foundations
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.
ALCHIMICA® provides below ground waterproofing solutions for basement external surfaces offering an excellent concrete protection in high performance applications. Our certified HYPERDESMO®-PB systems based on bitumen-extended polyurethane liquid membranes are the industry standard for almost 15 years and display exceptional properties which efficiently combine the traditional benefits of bitumen with ALCHIMICA’s polyurethane technology.
