This technique involves construction of concrete columns with a bottom-feed depth vibrator to transfer loads through weak strata to a firm underlying stratum.
Minipiles are a deep foundation element constructed using high-strength, small-diameter steel casing and/or threaded bars.
Driven precast piles are installed using impact or vibration hammers to a design depth or resistance.
When aquifers underlay made ground a stone column is sometimes perceived as potential path for contamination. In reality, vibro treatment reduces the mass permeability and so this is rarely an issue. However, in some cases it is necessary to seal the base of the columns. This is where Keller’s…
Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
