Cross to space

The Cross to Space iFLEX 150 WR 3M is a polyethylene membrane with a bitumen coating designed to work in zones highly exposed to groundwater and hydrostatic pressure. The bitumen layer actively blocks water ingress, creating a continuous sealing line at the planned section weakening so that the construction joint and the controlled crack zone remain watertight throughout the structure’s service life. The standard 3 m length makes it easy to match the element to typical pour widths, while the possibility of overlapping joints allows fast creation of a continuous seal along long wall, slab and retaining wall sections. The cross is equipped with a protective film that is removed immediately before concreting, providing a clean, active bitumen surface and maximum adhesion to concrete. Using iFLEX 150 WR 3M enables controlled crack induction in walls and foundation slabs, reducing the risk of uncontrolled cracking and leakage in retaining walls, foundation walls, underground garages, tanks and wastewater treatment plants, wherever reliable sealing of joints or expansion gaps and vertical sealing of structures is required.
