Ground improvement techniques are used to prepare the ground for new construction projects and to reduce the risk of liquefaction in areas of seismic activity.
Specialty grouting
Specialty grouting strengthens target areas in the ground and controls ground water flow through rocks and soils by
reducing their permeability.
Piling
Piling involves the installation of structural elements to transfer foundation loads through weak soils to stronger underlying ground.
Post-tension cable systems
Post-tensioning is used to reinforce concrete foundations and structural spans, enhancing their load-bearing capacity by applying a compressive force to the concrete, once set.
Structural restoration
Social housing refurbishment,
together with water and car park related concrete repair services.
