Description

Injection grouting is a process of injecting a fluid material (such as cementitious, resin-based, or chemical grouts) into cracks, voids, or weak areas in concrete, masonry, or soil to enhance structural integrity, reduce water infiltration, and improve load-bearing capacity. Types of Injection Grouting: Cementitious Grouting – Uses cement-based materials to fill voids in concrete or soil. Chemical Grouting – Utilizes polyurethane, epoxy, or acrylic resins to seal cracks and control water leakage. Polyurethane Grouting – Expands upon injection to stop leaks and fill voids. Epoxy Grouting – High-strength grout used for structural repairs in concrete. Silicate Grouting – Used for soil stabilization and underground applications. Applications of Injection Grouting: Repairing cracks in concrete structures (bridges, tunnels, buildings). Waterproofing basements and underground structures. Soil stabilization to prevent erosion or settlement. Strengthening old masonry walls. Filling voids in deteriorated concrete.
