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 the improvement of weak soils by the installation of densely compacted columns made from gravel or similar material with a vibrator. The displacement process reinforces all soils in the treatment zone and densifies surrounding granular soils. It’s a technique first…
Minipiles are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.
Compaction grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes.
Single bore multiple anchor (SBMA) are ground anchors with multiple strands, each bonded to the soil/rock and carrying a load.
Soil nailing uses grouted steel nails to reinforce in situ soils and create a gravity retaining wall for permanent or temporary excavation support.
Driven precast piles are installed using impact or vibration hammers to a design depth or resistance.
This technique involves construction of concrete columns with a bottom-feed depth vibrator to transfer loads through weak strata to a firm underlying stratum.
