PILING WORKS
CAISSON PILE
Caisson piling works involve the manual excavation of soil to a pre-determined depth. As the manual excavation takes place, the walls of the excavated shaft are supported by casting a ready-mix concrete lining. Following which, a steel reinforcement cage is inserted into the shaft, and ready-mix concrete is poured into the shaft and left to set.
BORED PILE
Bored piling works are performed by excavating soil using rotary boring rigs to form a shaft at a pre-determined depth, along with inserting a temporary steel casing to prevent the surrounding soil, rock and other materials from collapsing into the excavated area. Once the excavation process is completed, unwanted debris is cleared and a steel reinforcement cage is inserted into the shaft before ready-mix concrete is poured into the shaft and left to set
MICRO PILE
Micropiling works are performed by using drilling machines to carry out the same excavation process as bored piles. Once the excavation process is completed and unwanted debris is cleared, steel reinforcement bars or steel pipes are inserted into the shaft before cement grout is poured into the shaft and left to set. Micropiles are smaller in size and generally have a diameter of less than 300 millimetres.
BARRETTE PILE
Barrette piles are piles with rectangular cross-section. The excavation process of barrette piles is similar to bored piles, but using hydraulic grab machines. Once the excavation process is completed and unwanted debris is cleared, a steel reinforcement cage is inserted into the shaft before ready-mix concrete is poured into the shaft and left to set.
