Product Information

Full details

The Growtivation Siteworx Fibreboard Expansion Joint Filler is an essential material for professional contractors and serious DIYers looking to protect concrete structures from stress-related cracking. By providing a compressible barrier that accommodates thermal movement, this bitumen-impregnated board ensures long-term structural integrity in both commercial and residential settings. While it offers excellent moisture resistance and durability, users should ensure the joint dimensions match the 12mm thickness to guarantee a proper fit during installation.

FAQs

Can this product be used outdoors?

Yes, the bitumen impregnation is specifically designed to resist moisture and environmental exposure, making it ideal for outdoor driveways and walkways.

Does the board rot over time?

No, the bitumen-impregnated fibreboard is resistant to rotting and decay, even when buried within concrete.

How many strips come in a pack?

Each pack contains 10 strips, each measuring 2440mm in length.

Is this suitable for internal flooring?

Yes, it is suitable for both internal and external concrete slab construction.

Can I use this for vertical joints?

Yes, the material is versatile enough to be used in various concrete configurations where expansion space is required.

Troubleshooting

Board moving during concrete pour

Use temporary stakes or adhesive to hold the board firmly in place against the edge of the formwork.

Board is too long for the joint

The fibreboard can be easily cut to size using a standard hand saw or utility knife.

Pros and Cons

Pros

High resistance to moisture and environmental degradation
Easy to cut and fit into specific joint configurations
Provides reliable protection against slab cracking
Suitable for both residential and commercial infrastructure

Cons

Fixed 12mm thickness may not suit non-standard joint gaps
Requires proper sealing to ensure a completely watertight finish
Bulk size requires adequate storage space for unused strips

Setup, Compatibility & Care

Installation is straightforward but requires attention to alignment. Before pouring concrete, place the fibreboard strips along the planned joint lines. If the length of your project exceeds 2440mm, place the boards edge-to-edge with no gaps to maintain a continuous barrier.

For care and maintenance, ensure that the joint is properly sealed at the surface level with an appropriate joint sealant if the application requires a watertight finish. The boards themselves are designed to be permanent, so no specific removal or maintenance is required after the concrete has cured, provided they were installed flush with the desired surface level.
