Concrete Reinforcements Accessories - Expansion Joint Foam- 75mm
The 75mm Adhesive Expansion Joint Foam is a high-performance closed-cell polyethylene foam designed to create reliable expansion voids in concrete movement joints. Featuring a strong adhesive backing, this joint filler easily adheres to walls, slab edges, columns, and other substrates, helping reduce installation time and minimising the need for mechanical fixings or fasteners.
Manufactured for durability and flexibility, the foam compresses under movement and recovers effectively, allowing concrete slabs to expand and contract without causing cracking or structural stress. The product is supplied with a convenient 10mm tear-off strip (“zipped” top section), enabling installers to remove the top portion after concrete placement and create a clean recess ready for joint sealants or silicones.
Ideal for commercial, industrial, and residential concrete applications, this lightweight expansion joint foam is easy to cut, shape, and install on-site.

Benefits of Adhesive Backed Expansion Joint Foam
Using adhesive-backed foam expansion jointing improves installation efficiency while providing long-term joint performance. The adhesive backing keeps the foam securely positioned during concrete pours, helping installers achieve accurate joint placement without additional fixings.
The closed-cell structure helps resist moisture absorption and assists in protecting joints from dirt infiltration. The removable 10mm top strip creates a professional finish by allowing space for flexible sealant application, improving joint longevity and appearance.

- Cut foam jointing to the required length.
- Peel off the adhesive backing liner.
- Position and press firmly against the wall, slab edge, or formwork.
