A seamless alternative to conventional roof membranes

Our polyurea roofing membranes offer an alternative to systems such as Butynol, EPDM rubber, TPO, torch-on bitumen and reinforced liquid-applied membranes such as Chevaline Dexx. The appropriate system depends on the roof construction, substrate and project specification.

Polyurea is applied in place to form a seamless spray applied membrane across the prepared roof surface and detailed junctions. It does not rely on the overlapping sheet seams used in sheet membrane systems. Roof edges, penetrations, outlets and movement joints are detailed as part of the complete waterproofing system.

Polyurea membranes for internal gutters

LJ Solutions applies seamless polyurea membranes to internal gutters, forming a continuous waterproof lining along the gutter and around detailed junctions and outlets.

The spray applied membrane follows difficult shapes and unique detailing, including tight corners, changes in profile and complex junctions that can be challenging to waterproof with other membrane types.

We assess the gutter substrate, existing lining, falls, outlets and connections to the roof before specifying preparation and application. For existing gutters, the condition and compatibility of the lining determine whether it can be overcoated or needs removal and repair.

Planter boxes, warm roof systems and green roofs

Talk to LJ Solutions about polyurea waterproofing for planter boxes, warm roof systems and green roofs, also known as living roofs or roof gardens. We assess the membrane as part of the complete system, including insulation compatibility for warm roofs and drainage, membrane protection and root-barrier requirements for planted areas.
