The Siteworx Fibreboard Expansion Joint Strip is designed for contractors and DIY enthusiasts who need a reliable solution for managing movement and preventing cracking in concrete structures. By offering superior moisture resistance through its bitumen-impregnated fibreboard composition, it ensures structural longevity in expansion joints, though it requires careful handling during installation to prevent edge damage before the concrete is poured.

Yes, the fibreboard is suitable for both horizontal slab joints and vertical expansion gaps.
For optimal results in areas prone to heavy rain or chemicals, applying a flexible joint sealant over the top of the fibreboard is recommended.
The bitumen impregnation provides high resistance to rot and moisture, making it durable for long-term ground contact.
Yes, it is highly effective for indoor applications such as warehouse or garage floors to accommodate movement.
While exact shipping weight varies, the boards are lightweight enough to be handled by a single person on site.
Use a standard wood saw to cut the fibreboard to the precise length required for your specific joint run.
Secure the board using temporary stakes or nails to ensure it stays perfectly vertical against the joint face.
To install, ensure the ground is level and the joint area is clean of heavy debris. Use a standard hand saw or utility knife to trim the 2440mm strips to your desired length. When placing the strips, stake them securely against the formwork or adjacent slab to prevent movement during the concrete pour. Care should be taken not to soak the boards in water before installation, as although they are moisture-resistant, they perform best when kept dry until the concrete cure-time begins. Store unused strips in a cool, dry place away from direct sunlight to maintain the integrity of the bitumen impregnation.
