Construction technique & application
Driven piles are installed by dropping a hammer weight on a pre-formed pile. When the pile moves a predetermined distance for a given hammer drop height, the pile capacity has been achieved.
Central Piling offer a bottom driven steel cased system with additional sections of casing being welded on as required. Reinforcement and concrete is then placed in the casing to provide a connection to the overlying structure. On selected contracts we can also provide pre-cast concrete piles.
Driven piling is particularly appropriate where soft and alluvial soils overlay dense sands and gravels.
Plant & equipment
To carry out driven piling we utilise 25T crane mounted crawler rigs, 55T hydraulic rigs and where access is restricted a 2.5T mini rig. If necessary machines can be supplied to pre-bore through the upper material.
