Pile Head Treatment System
What is a Pile Head/Cap?
A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the foundation of a building, typically a multi-storey building, structure or support base for heavy equipment. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a “raft”, which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence.
The Advantage of Pile Head/Cap Treatment:
The Pile Head Treatment is the final working step of a successful piling and foundation system. Every pile has to be protected against chloride and sulphate attacks on the reinforcement caused by the soil and groundwater. It also has to assure that there will be no passage of water from the ground to the substructure. A proper designed system shall includes : re-profiling, waterproofing and full encapsulation of the entire pile head to assure that each and every structure is based on a long lasting and safely built foundation.
