Grouting

Permeation Grouting Services

Permeation Grouting consists of injecting grout under controlled, low pressure in order to permeate the strata without causing fracturing. It can be applied in both soil and rock. Cement grouts are typically used to treat the bedrock beneath dams. Fractures and joints in the rock can be easily sealed; reducing the overall permeability of the rock formation. This mitigates potential seepage related issues and increases the dam’s overall longevity.

Jet Grouting Services

Jet Grouting creates in-situ columns of grouted soil using very high pressure grout injection. Grouting is performed by pumping high velocity jets of grout (or sometimes grout and air or grout, water and air) through the side of a grout monitor, attached at the end of the drill string. The jets erode and mix the soil as the drill string and the monitor are being rotated and withdrawn.
