ESSRBOND GS 500 — Polyurethane Injection Grout for Crack Sealing and Concrete Leakage Control (5 kg)

Concrete structures develop cracks and leakage points through a combination of settlement, thermal movement, shrinkage, and sustained load — and the longer these entry points remain unaddressed, the deeper the deterioration they allow into the structure. Surface treatments manage symptoms at the surface level. Injection grouting addresses the problem at its source — delivering a sealing material directly into the crack or void where water is entering, and forming a permanent barrier at the exact point of ingress.

ESSRBOND GS 500 from Essrbond is a polyurethane injection grout engineered for crack sealing and leakage control in concrete structures. Injected through ports installed along the crack length, GS 500 penetrates the full depth of the crack under controlled pressure — filling the crack geometry completely and curing in place to form a reliable, watertight seal that stops water ingress at the source rather than redirecting or masking it.

The polyurethane formulation delivers a flexible cured seal that accommodates the natural movement of the concrete structure — thermal expansion and contraction, minor settlement and load-induced deflection — without cracking or losing its watertight bond over time. This flexibility ensures the repair remains effective throughout the service life of the structure rather than failing under the same movement conditions that contributed to the original crack.

For waterproofing and structural repair work on basements, underground structures, water retaining walls, tunnels and below-grade concrete elements where crack sealing and leakage control are the primary requirements — ESSRBOND GS 500 delivers the polyurethane injection performance that reliable, durable concrete waterproofing demands.

A construction chemical injection solution from Essrbond for crack sealing and concrete leakage control — GS 500 is the PU injection grout specification for waterproofing applications where the seal needs to reach the source, not just the surface.
