Waterproofing system with vacuum tightness control

Abstract

This utility model relates to construction, specifically to waterproofing systems for building structures with leak testing capabilities. The waterproofing system with vacuum leak testing comprises first and second layers of a polymer membrane, interconnected along the perimeter to form a sealed cavity. The second layer contains nozzles connected via control hoses to a vacuum pump and a vacuum gauge. The second layer is made of a textured membrane. The system creates negative pressure in the sealed cavity to test the tightness of the waterproofing section. The technical result is increased reliability of waterproofing leak testing and localization of damage within an individual section.
