Description

Pile collars are an effective solution to maintain ground heave protection around complex pile areas. Max Frank Ltd recommends the use of pile collars, together with Pecavoid and Claylite, to maintain a clear void and prevent the effects of clay heave. NHBC inspectors report that gaps can often be found where the square edges of the void former meet the circular pile. Unless this gap is properly filled with a void former, heave problems will occur. Pile collars of a suitable size, made from low density expanded polystyrene, can be provided to eliminate grout loss at pile positions.
