Dry soil mixing is a ground improvement technique that improves soft, high moisture clays, peats, and other weak soils, by mechanically mixing them with dry cementitious binder.
Jet Grouting uses high velocity fluid jets to construct cemented soil of varying geometries in the ground.
Ground anchors transfer tensile loads and consist of an anchor head, a free length and a bond length. The free length enables the anchor to be, a big advantage for excavation pits with very low 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.
Mass Soil Mixing (MSM), or mass stabilisation, is a ground improvement technique that improves soft or loose soils, by mechanically mixing them with either wet grout or dry cementitious binder.
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.
Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator. It’s a technique first developed by Keller in the 1930s that we’ve used on thousands of projects since.
This technique involves construction of loadbearing columns made from gravel or crushed stones with a vibrator to reinforce all soils in the treatment zone and densify surrounding granular soils. It’s a technique first developed by our company founder, Johann Keller, that we’ve used on thousands…
Dynamic compaction involves the controlled impact of a crane hoisted weight, of around 10-30 tonnes, falling in a pre-determined grid pattern to improve loose, granular soils and fills.
Rapid impact compaction densifies shallow, granular soils, using a hydraulic hammer, which repeatedly strikes an impact plate on the ground surface.
Rock grouting is normally done in fissured rock to reduce the flow of water along the joints and discontinuities in the rock.
Low mobility (compaction) grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes.
Bulk filling generally uses a cement/pulverised fuel ash (PFA) mix to suit site conditions with compressive strengths in the order of 1.0 N/mm2. The mixes may include Sand and Bentonite etc as required. Gravel is introduced to fill major voids and/or to form containment barriers.
Micropiles, also known as minipiles, pin piles, needle piles, and root piles, are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.
Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
This technique involves construction of concrete columns with a bottom-feed, down-hole vibratory probe to transfer loads through weak strata to a firm underlying stratum.
Dynamic replacement is a variation on dynamic compaction and uses the energy of a falling weight to drive large diameter granular columns into cohesionless soils and fills.
