Ground Stabilisation


Our ground stabilisation techniques are based around a method of driving injection lances into soils in order to intersect the waterborne sands and gravels that constitute mobile ground.

 

Project specific resins are then injected through the injection lances in a continual, systematic, injection and retraction technique. On contact with water, the resin reacts to change from a low viscosity liquid, into a three dimensional, closed cell foam, that effectively fills the pores within the soils and closes off leak paths.

 

By careful injection under low pressure, the resin flows into the pores of the ground, reacts with moisture, and then expands to further permeate the soils. Whilst this reaction is taking place, the resin does not have any significant structural substance and will not move the ground, making it ideal for use in sensitive environments.

 

Once the resin has reached it's maximum expansion, the resin will continue to cure, eventually forming a mass of stabilised ground. This mass arrests the movement of water and fines within the soils, allowing for the excavation of underpins and foundations.

Advantages of resin injection in ground stabilisation

 

 

Injection lances can usually be driven in by hand tools up to a depth of two to three metres. Beyond this, a drilling rig is generally required. It is therefore advantageous in areas to be treated, to locally reduce the ground level to water table level.
