Ground Remediation By Resin Injection:
Restek uses traditional testing methods and our unique deep Ground Penetrating Radar – GPR for Highways or Rail to create a value-engineered solution, bespoke for each project. Our ground stabilisation techniques are value engineered and involve driving small, specialist injection lances into mobile ground consisting of loose soil, gravels & voids.
After reviewing the GPR data, we create and agree the remediation schedule with the client, we use a continual systematic injection and reaction technique to carefully monitor the stabilisation process. We inject a combination of different resin types, at varying depths and volumes through each lance. This multi-level, multi-resin injection procedure, ensures the correct resin is efficiently injected, at each level and at exactly the right amount through each lance.
Once injected, Restek resins undergo a chemical reaction, changing from a low-viscosity liquid to a solid. This process begins with foaming to four times the injection volume, which helps to significantly reduce the volume and weight of the injection product. This compacts and stabilises the surrounding loose ground & voids beneath the ground.
