Grouting
Grouting techniques can be used to provide a cost-effective solution to both temporary and permanent geotechnical problems such as voids, soft ground, settlement and water in-flow. Since we were founded in 1910, we have played a leading role in the development of grouting solutions, and we draw on this wealth of experience and resources to provide an effective grouting solution tailored to our client's needs.
Bulk In-fill Grouting/Ground Stabilisation
In order to provide economic foundation solutions, ground stabilisation has become widely used for turning weak soils into useful founding strata. This technique is often used in areas which have been heavily mined and involves in-filling voids with pressurised grout.
Permeation Grouting
This technique is used in basement construction. Shaft sinking, dam cut-offs and tunnel excavations all need ground water control. It relies upon the liquid grout flowing through the soil, displacing water and gases by forcing them out as the grout steadily advances.
Compensation Grouting
The excavation of tunnels produces settlement which can cause damage to structures which lie on or near their path. Compensation grouting reduces, or even prevents, settlement by injecting relatively small quantities of grout between the source of the settlement and the foundations of the structures that require protection.
Compaction Grouting
Stiff sand and cement mortar grout is injected into granular materials at relatively close centres to provide compaction of the soil.
Jet Grouting
Cementitious grout columns are formed in granular material by combining the granular material with the grout under pressure.
Chemical Grouting
Chemically based grouts can be injected into various fine-grained strata to stabilise the material.
