Self-Adhesive Closed-Cell Polyethylene Expansion Joint Foam

Expansion foam joint a Zipped, low cost, closed-cell polyethylene joint filler mainly used as an expansion joint filler in concrete and brick work. It is Ideal for submerged and high foot traffic areas. t has an adhesive backing which makes it perfect for sticking to walls around the outside edges of a new concrete slab. This product has a variety of applications in filling an expansion joint gap in road, bridge and building construction, and wherever low load joint fillers are required in concrete and construction work. It can be used as a gap filler in any area where concrete expansion, ground or building movement would otherwise cause damage without the gap. This expansion joint filler foam will also act as a backup strip to support sealants in floor and wall joints and can be used as lagging to create space around pipes and vessels.

As a manufacturer of expansion joint foam strip, we have a glue application workshop and a mechanical cutting workshop to ensure that the adhesive properties and dimensions of our products meet the needs of our customers' use.
