Bored piles are a very effective, state-of-the-art construction element with many applications in foundation and civil engineering.
A temporary casing is installed and soil drilled out using specialised tools. If the hole requires support to remain open, additional casing or, occasionally, drilling fluid can be used. Full length reinforcing steel is lowered into the hole which is then filled with concrete. Bored piles can be drilled to depths in excess of 60m and typical diameters range up to 2.4m.
We use a variety of quality assurance methods for our products including top down and integrity testing, bottom bi-directional pile load tests, and digital recording and logging of the execution parameters.
