The Siteworx Fibreboard Expansion Joint Filler is an essential solution for professional contractors and DIY enthusiasts looking to protect concrete surfaces from cracking due to thermal movement. By providing a compressible, bitumen-impregnated barrier, this product ensures structural integrity in both commercial and residential projects. While it is highly durable and moisture-resistant, users should note that the rigid nature of the boards requires careful planning during installation to ensure they fit correctly within tight or irregular joint spaces.

Yes, the bitumen-impregnated fibreboard is specifically designed to resist moisture and environmental exposure, making it ideal for exterior use.
The bitumen impregnation provides high resistance to moisture and decay, preventing the fibreboard from rotting under normal conditions.
Each pack contains 20 strips of the Siteworx Fibreboard Expansion Joint Filler.
A standard heavy-duty utility knife or a fine-tooth hand saw is sufficient for trimming the boards to your required size.
Yes, it is highly effective for indoor or outdoor concrete slab joints where thermal expansion needs to be managed.
Use a sharp utility knife to trim the edges carefully or consider a thinner alternative if the gap is narrower than 12mm.
Use small wooden stakes or adhesive tape to keep the filler strip in place until the concrete is poured around it.
To install, measure your concrete joint length accurately before cutting the fibreboard with a sharp utility knife or hand saw. Place the strips into the desired position, ensuring they are held securely before the concrete pour. For deep joints, you may need to stack strips, though they are specifically gauged at 12mm for standard applications.
Regarding care, the bitumen impregnation provides inherent protection against the elements, meaning no additional sealants or coatings are required before the initial installation. Store the product in a dry, flat area to prevent the boards from warping or becoming damp before use.
