Underpinning describes the process of improving or increasing the capacity of an existing structures foundation. This can be achieved by the introduction of grout or more commonly by extending the foundation in depth, typically by the introduction of piles so a structure is supported on a more supportive stratum.
Underpinning of a structure maybe required […]
Soil nailing is an efficient, effective and economical method of earth reinforcement, which allows a controlled improvement of the natural stability of the soil. Soil nails provide friction, shear and tension strength in loose materials, so that when a site is completed it transforms from many independent objects by joining and combining the site […]
Cement Grouting
Pressure Cement Grouting, is a grouting process that fills pores in granular soil or voids in rock or soil, with grout injected as a flowable medium. Depending on the application, cement grout is injected under pressure at strategic locations via a single or multiple ports. It is essential that the particle size of […]
Grout retaining walls are created from grouted soil columns utilising high pressure grout techniques, mini jet and jet grouting. These grout columns combine to produce panels which are typically installed to a design specification to create a gravity retaing wall. Grout walls can be created in all geotechnical conditions however they are specifically suited […]
Soldier piles and lagging walls is an earth retention technique used primarily for temporary excavation support. These shoring walls are typically constructed by installing steel beams vertically (soldier piles), which are either driven or drilled at regular intervals around the planned excavation prior to excavation beginning.

Reticulated micropiles are typically utilised as components of a reinforced soil mass, which is used for stabilization and support, as examples unstable slopes or in areas where additional capacity needs […]
