Overview:

GSI’s polyurethane grouting provides a fast, non-disruptive solution for lifting and re-leveling buildings, concrete slabs, and pavements while stabilising weak or subsiding ground. By injecting an expanding resin beneath the surface, settled structures can be raised, voids filled, and soil strength increased – all without excavation or demolition.

Ideal for re-leveling slabs and footings, improving ground stability, and sealing water ingress, polyurethane grouting delivers precise, millimetre-accurate results with minimal downtime. The lightweight, high-strength resin reinforces soils without adding significant load and is water-resistant, durable, and designed for long-term performance across residential, commercial, and infrastructure projects.
