Product Description

Expandafill is a closed-cell, polyethylene joint filler for use as an expansion joint filler in concrete, brickwork and blockwork. Being low density it is also useful for forming isolation joints for machine bases or similar locations. The low compressive strength prevents the transfer of load across joint interfaces and makes it ideal for forming soft compression joints and expansion joints in brickwork facades, as recommended by BS5628: Part 3: 1985- Use of Masonry, Clause 20.4.
