FAQs
Which size should I choose?
Use a full or half roll for large installations. Smaller cut sheets suit patch repairs, localised projects, or DIY tasks like gravel paths or trench lining.
Can this membrane be used under a horse arena?
Yes, NW8 is commonly used as a filtration and separation layer in manèges and paddocks, especially beneath a tread layer or EcoGrid base.
Is it suitable for soakaways and French drains?
Yes, NW8 has high flow rates and optimal pore size, making it ideal for wrapping drainage systems and preventing clogging from fine soil.
Can I lay it directly on soil?
Yes, for most uses, it can be laid straight on compacted ground. Avoid driving on it before covering with a suitable fill layer.
How do I join pieces together?
Overlap sheets by 300–600mm and secure with fixing pegs. For best results in wet areas, use geotextile jointing tape.
