Expandafoam 2.4m x 1.2m x 15mm Fosroc

Expandafoam is a closed-cell polyethylene joint filler for use
as an expansion joint filler in brick and blockwork, isolation
joints and hinge joints where a readily compressible low load
transfer joint filler is required.
Expandafoam is also used as back-up strips for elastomeric
sealants placed in joints of concrete floors subject to foot traffic
and light wheel loads.
