Steel driven cased piles offer a suitable alternative for a wide ranger of confitions when piling into sands, gravel, clays, and typically when driving through fill, overburden and into bedrock. The advantage of cased piles is minimal spoil is generated, good axial and sheer capacity, prevention of concrete/grout loss (thus ensuring the pile intergrity) and minimal site preparation.
Denver Drilling Services specialise in providing solutions to all types of foundation problems and offer a full design and installation package for all mini piling requirements. Our fleet of TD610 hydraulic mini piling/drilling rigs are designed to drill up to 500mm diametre augered piles, and can also be used for rotary percussive bottom driven steel tube piling. With a 100mm diametre hollow main shaft in the rotation head concrete can be pumped directly to the bottom of the pile for C.F.A work. This makes the TD610 the ideal mini piling rig to overcome any difficult operation conditions such as restricted access, difficult ground, limited headroom and environmental restrictions.
