Ground anchors transfer tensile loads and consist of an anchor head, a free length and a bond length. Anchors can offer an advantage for basements and large excavations by minimising horizontal deflections.
Wet soil mixing, also known as the deep mixing method, improves the characteristics of weak soils by mechanically mixing them with cementitious binder slurry.
King post walls are a cost-effective system of temporary or permanent retention using beams and precast concrete panels.
Slurry walls are constructed using a cement-bentonite slurry to produce a below ground low permeability barrier.
Permeation grouting, also known as cement grouting or pressure grouting, fills cracks or voids in soil and rock and permeates coarse, granular soils with flowable particulate grouts to create a cemented mass.
Dynamic compaction involves the controlled impact of a crane hoisted weight, of around 10-12 tonnes, falling in a pre-determined grid pattern to improve loose, granular and mixed soils and fills.
This technique involves construction of concrete columns with a bottom-feed depth vibrator to transfer loads through weak strata to a firm underlying stratum.
