DAMP COURSE

What It Is
Damp Course 300mm is a high-quality, flexible polyethylene membrane designed to prevent rising damp in masonry construction. Installed between brickwork or blockwork layers, this 300mm-wide barrier stops moisture from penetrating walls and compromising structural integrity. It's an essential component for long-lasting, moisture-resistant builds.

Key Features

• 300mm Width: Ideal for standard and wide wall construction, offering broad coverage.
• Moisture Barrier: Effectively prevents rising damp from reaching above-ground structures.
• Durable Polyethylene: Strong, tear-resistant material built to withstand the rigours of construction.
• Flexible & Lightweight: Easy to handle, cut, and install on-site.
• Code-Compliant: Meets Australian standards for damp-proofing in residential and commercial builds.

Benefits

• Protects Building Integrity: Blocks moisture that can lead to efflorescence, mould, and decay.
• Essential for Compliance: Required in most masonry builds under local building codes.
• Low Maintenance: Once installed, provides long-term protection with no upkeep needed.
• Versatile Use: Suitable for cavity walls, solid brickwork, and block walls.
• DIY or Trade Ready: Simple to cut and install with minimal tools or training.

Landscape Ideas

• Garden Walls: Use between footings and blockwork to prevent moisture wicking.
• Planter Boxes: Protect exterior brickwork from damp soil contact.
• Retaining Walls: Include in your wall system to shield against groundwater rise.
• Outdoor Kitchens or Bar Areas: Keep masonry bases moisture-free and structurally sound.
• Boundary Fences: Extend the life of rendered block or brick fence walls.

How to Use It

1. Cut the Damp Course to the required length using scissors or a utility knife.
2. Lay the membrane flat between courses of bricks or blocks, ensuring full coverage of the wall width.
3. Overlap joins by at least 100mm for full protection.
4. Ensure the damp course sits above ground level and is continuous across the structure.
5. Continue with the next course of masonry on top of the membrane.

Coverage Example
Sold by roll or metre—check the product length to match your wall project.
At 300mm width, it suits most double-brick or wider wall constructions.
As a guide:

• For a 10m wall, you’ll need 10 linear metres of Damp Course at 300mm wide.
