Extensions

We carry out a significant number of extensions every month, installing either bottom driven steel cased or open hole augered piles. These piles are ideal solutions if either poor ground conditions are encountered, or existing drains are within the proposed footprint. Access conditions are also kept to a minimum as only a standard doorway's width would be needed for the piling equipment.

Typical single storey extensions measuring 6.0m by 3.0m can usually be completed within 2 to 3 days, dependent upon the pile depth. A 450mm wide by 300mm deep reinforced concrete ground beam would be installed 150mm below existing ground level.

For a two storey extension of the same measurements, additional piles would be required due to the increased loading, but we would still expect to complete the works within 4 to 5 days, again dependent upon the pile depth. Our reinforced concrete ground beam would again be installed to a depth of 150mm below existing ground level, but would be thickened to 450mm in depth.

If existing or proposed drainage is required to be placed through our R.C. works, it would be lined with rockwall or similar approved lining, subject to the building control officer's requirements.

In cases where the building contractor has already started the trenches with a 600mm wide bucket, we can either flood the excavations, or use our proprietary shuttering system if you prefer.
