Product Type



A below-grade expansion joint system, BG System can be installed onto the exterior of free-standing foundation and tunnel walls, against the retaining wall (blind-side) on one-sided formed walls, and sub floor joints, prior to casting concrete against lagging or prepared sub floor base.

BG System features heavy-duty, extruded multiple-cell thermoplastic gland, with dual flanges for a secure tie-in to the waterproofing system. The flanges are sandwiched within, welded, or adhered to layers of the below-grade waterproofing membrane. The assembly is secured to the structure with mechanically-fastened termination bars.

The BG System is integrated into the waterproofing membrane using accessories offered by the waterproofing membrane manufacturer. It is heat-weldable, uniquely ensuring continuity of seal through factory-welded transitions and terminations.
