FAQs
How do I install this membrane?
Prepare your subbase, ensure it’s level, then roll out the membrane with minimal overlap. Secure using fixing pegs or weighted cover materials.
Is this suitable for wrapping soakaway crates?
Yes, this 100gsm non-woven membrane is ideal for crate wrapping in both residential and commercial systems.
Can it be used under gravel or paving?
Absolutely – it separates sub-base layers and prevents gravel from mixing into the soil.
Does it stop weeds?
It acts as a barrier to suppress weeds coming from below. Note: seed drop from above may still result in surface weeds.
Is the fabric biodegradable?
No. It is made from polypropylene, designed for long-term ground use without breaking down.
