Basement and foundation waterproofing is the process of protecting the lower levels of a building against water intrusion. It involves the techniques of sealing cracks by applying membranes in retaining walls and horizontal surfaces and installing drainage systems to prevent water damage, mold growth, and structural issues. ALCHIMICA’s bitumen extended polyurethane technologies are the industry standards for this crucial stage of construction ensuring secure dry foundations and retaining walls, protecting in that way properties from moisture-related concerns.
