Weed-Defenda 90gsm Woven Weed Control Membrane

Weed-Defenda 90gsm is a strong, economical woven weed control membrane designed to suppress weeds and rhizome growth while allowing water, air and nutrients to pass through to the soil. With a 90gsm woven construction, this permeable weed control fabric provides greater load capacity than lighter non-woven alternatives, making it a practical choice for domestic gardens, landscaping projects and areas covered with gravel, stone, bark or other decorative materials.

The woven weed membrane creates an effective physical barrier against unwanted weed growth without relying on chemical weed treatments. It is ideal for use beneath gravel driveways and paths, decorative stone, bark and mulch, artificial grass, patios, decking, raised beds and planting areas. The fabric is UV stabilised and easy to handle, simply unrolling across the prepared area and cutting to size with scissors for straightforward installation.

Weed-Defenda 90gsm provides a long-lasting solution for weed suppression and landscape maintenance. When exposed to UV light without mulch, it has a stated life of up to 7 years, while installation beneath mulch can extend its stated life to up to 40 years. Available in a range of widths and roll lengths, it is suitable for both smaller domestic gardening projects and larger landscaping applications.

Weed & Rhizome Control

Weed-Defenda 90gsm acts as a physical barrier between the soil and surface landscaping materials, helping suppress unwanted weed growth and rhizome spread.

Unlike chemical weed treatments, the membrane provides mechanical weed control while remaining permeable. Water, air and nutrients can pass through the woven structure to the underlying soil, making it suitable for use around landscaped and planted areas where maintaining soil conditions is important.

For best results, the membrane should be installed over suitably prepared ground and covered with the intended surface material where possible.

Permeable Weed Membrane

The woven construction allows water to pass through the fabric rather than creating an impermeable layer. This helps maintain drainage through gravel, bark, mulch and other permeable landscaping finishes.

The membrane can therefore be used beneath decorative aggregates, paths and other landscaped surfaces where weed suppression is required without unnecessarily restricting water movement through the ground.

Gravel, Bark & Decorative Landscaping

Weed-Defenda 90gsm is particularly useful beneath loose decorative landscaping materials such as gravel, stone chippings, bark, mulch, pebbles and decorative aggregates.

When installed beneath these materials, the membrane helps separate the surface covering from the underlying soil while suppressing weed growth. This can help keep landscaped areas looking cleaner and reduce the maintenance required to remove unwanted vegetation.

For gravel paths and driveways, the 90gsm woven construction also provides a stronger fabric option than lightweight weed control membranes.

Artificial Grass, Patios & Decking

The membrane can also be incorporated beneath artificial grass, domestic patios and decking as part of an appropriately prepared installation.

Under decking and artificial grass, Weed-Defenda 90gsm can help suppress weed growth from the underlying soil. It can also be used around patios and other hard landscaping areas where vegetation needs to be controlled around or beneath the finished surface.

Installation Guidance

Weed-Defenda 90gsm is straightforward to install:

1. Prepare the area by removing existing weeds, vegetation and unwanted debris.
2. Level and compact the ground where appropriate for the intended application.
3. Unroll the weed control membrane across the prepared area.
4. Cut the fabric to the required shape and size using scissors.
5. Overlap adjoining sections where required to provide continuous coverage.
6. Secure the membrane using suitable landscape fabric fixing pins or pegs.
7. Cover the membrane with the selected surface material, such as gravel, bark, mulch, stone or decorative aggregate.

Where the membrane is being used beneath artificial grass, patios, decking or other constructed surfaces, the overall installation should follow the requirements of the finished surface system.

Covering the membrane with mulch or another suitable landscaping material also helps protect it from prolonged UV exposure and can significantly extend its stated service life.
