Rotary piles have the ability to quickly change coring or digging tools and auger type. Bored rotary piles also have the advantage of having the reinforcement cage installed into the open bore and so can accommodate full-length reinforcement. Primarily used for large public, commercial and industrial developments as well as transport infrastructure projects. We have specialist expertise in delivering large, complex and technically challenging projects.
