Externally applied water management system, used to protect and drain the basement or structure.
A cold applied impermeable high density polyethylene profiled sheet incorporating a permeable geotextile filter fabric designed to prevent ground water reaching a structure and enhance the performance of the waterproof membranes.
The product can be used in conjunction with a primary waterproofing system or on its own to isolate the structure from the surrounding soil and relieve hydrostatic pressure by promoting the flow of ground water away from the face of the structure to land drainage. CE marked, the system can also be used to provide protection to a primary waterproofing system against backfilling and mechanical damage.
Features and benefits:
Fixing to vertical/ sloping surfaces:
Jointing:
70 mm overlaps, with geotextile fabric-patch bonded with bonding tape.
Deformation under long term loading:
25% maximum.
