What is a pile collar used for?
A pile collar is used to provide a compressible void around a pile so clay heave can occur without pushing upward into the pile cap or ground beam.

Selection depends on the required void height and project specification. If you’re unsure, call Next Day Steel on 020 8079 7719 and we’ll help you match the correct option.
