Complete Waterproofing Protection — from Rooftops to Below-Grade Structures.

The JSMS Cementitious Epoxy 4L is a compact, highly effective waterproofing and surface protection solution designed for both residential and commercial applications. Unlike conventional waterproofing membranes that sit on top of a surface and eventually delaminate, JSMS Cementitious Epoxy bonds monolithically — penetrating and integrating with the substrate to create an impermeable barrier that becomes part of the structure itself.

Its vapor-permeable formulation prevents hydrostatic delamination — one of the leading failure modes of conventional waterproofing systems — while its epoxy-cementitious chemistry provides structural reinforcement alongside moisture protection. The 4L jericane format is ideal for detailed application areas and projects where precise quantity management is essential.
