Black Plastic (4m wide)

Our heavy-duty black plastic (builders film) is commonly used for:

• Weed suppression under paths and landscaping
• Moisture barriers beneath concrete slabs
• Ground cover on construction sites
• Protecting soil beneath gravel or pavers
• Erosion and dust control

Our black plastic is a 200UM polythene builders film. It is compliant with Australian Standards AS2870 and AS2904, as well as the National Construction Code (NCC), making it suitable for both residential and commercial projects.

A 200UM rating is classified as a heavy-duty (medium impact) builders film. In Australia, 200UM plastic is the minimum legal requirement for use as a vapour barrier beneath concrete slabs and within wall framing.

This thickness is also ideal for landscaping applications, including weed suppression and as a separation barrier between different materials.3. How do you install black plastic correctly?

To install black plastic, first clear the area of debris, rocks, and any sharp objects that could puncture the plastic. Before cutting the plastic, measure and plan your coverage. To help create a waterproof barrier, we recommend allowing a 200mm overlap between adjoining sheets.

Finally, cut the black plastic to size and lay it in position. Use builders' tape to seal the overlapping joins and edges, creating a continuous waterproof barrier.

Yes, black plastic is waterproof, but its effectiveness depends on how well the joins and edges are sealed. This is why it is important to allow extra material for overlapping, ensuring you can create a continuous waterproof barrier.

Black plastic is also highly effective at blocking sunlight, making it an excellent weed suppressant. For the best results, we recommend covering it with mulch, gravel, or decorative stone.
