Mini bottom-driven piles are efficient and suitable for most ground conditions. Spoil removal is not required – a particular advantage on brownfield sites. A closed-ended thin walled steel tube is driven in lengths of between 2 and 6m using an internal drop hammer on to a dry concrete plug. The tubes are joined by a full but non-structural fillet weld as the installation proceeds. The pile is driven to a predetermined set or design length criteria. Once the required depth is reached the tube is filled with high slump concrete or grout and a single bar or cage is inserted.
