​Bored piling is an efficient method of construction which utilizes reinforced concrete piles to support high buildings for vertical bearing and also for constructing retaining walls that require resistance in the horizontal direction. It is a method that involves boring a circular hole into the ground, installing steel reinforcement and filling the bore hole with concrete to form a pile. McMillan Civil have extensive experience in cast-in-place bored piling and can handle any project size. Our technologically advanced fleet of Casagrande rigs can achieve piles with high bearing capacities in most soil types.
