Product Information

Full details

The SITEWORX Polyethylene Foam Expansion Joint Filler is an essential material for professional contractors and DIY enthusiasts looking to manage structural movement in masonry. It provides a durable, compressible seal for expansion joints in brickwork and blockwork, effectively preventing moisture ingress and ensuring structural integrity. While it is highly efficient and easy to install, users should note that the 10mm thickness is fixed, making it critical to measure joint widths accurately before application.

Extended Product Information

FAQs

Can this filler be used outdoors?

Yes, its low moisture absorption makes it highly suitable for external brickwork and blockwork.

Is this product fire-resistant?

The material is polyethylene-based and is not intended for use as a fire-stopping material.

Can I paint over this filler?

The filler itself is not intended to be painted, but it is typically covered by a sealant which can often be color-matched or painted.

How long is the roll?

Each roll provides 10 meters of filler.

Is it suitable for concrete floor joints?

While intended for brick and blockwork, it can be used for light-duty gaps, but always consult structural specifications for heavy-duty load-bearing floor expansion joints.

Troubleshooting

Foam does not stay in the joint during installation

Apply a small amount of non-solvent adhesive or mechanical fixing to hold the strip in place until the final sealant is applied.

The foam is too thick for the joint gap

Use a sharp blade to carefully shave the thickness of the foam until it fits snugly into the gap without forcing the masonry apart.

Pros and Cons

Pros

  • Resistant to moisture and rot
  • Highly compressible for easy installation
  • Lightweight and easy to transport
  • Excellent for both trade and DIY use

Cons

  • Thickness is limited to 10mm
  • Not suitable for high-temperature applications
  • Requires proper sealing if exposed to direct UV

Setup, Compatibility & Care

To install, simply measure the height of the intended joint and cut the foam strip to the necessary length using a sharp utility knife. Ensure the joint is dry and clean before pressing the filler into place. This product is compatible with most standard neutral-cure masonry sealants. To maintain the integrity of the filler over time, it is recommended to finish the joint with a high-quality joint sealant to protect the foam from direct sunlight and environmental debris. Keep the roll stored in a cool, dry place away from direct sunlight when not in use to prevent the polyethylene material from becoming brittle.
