Can I Use These Membrane Products Outside the Van?

Q: What can be used outdoors?

The most relevant products for exterior work are the Groundtex woven weed membrane and its matching plastic fixing pegs . The membrane is a woven polypropylene sheet that covers 20m², which suits small patios and retreat areas beside a campervan. The pegs are UV-stabilised, weather-resistant, and designed with a barbed spike to grip soil or compacted sub-base. Use beneath patios, pathways and resin bound surfaces Suitable for soil, compacted sub-base and aggregate bases Not intended as a visible surface layer or permanent finish

Heavy-duty geotextile membranes and plastic fixing pegs are suitable for outdoor use beneath patios, pathways, and retreat areas attached to a campervan. The woven polypropylene membrane helps stabilise the ground and reduce weed growth, while UV-stabilised pegs hold it securely in soil or compacted sub-base. This combination provides a firm, even foundation before adding a resin bound surface, aggregate, or paving layer. Both products are intended for ground-level preparation rather than exposed finished surfaces.

Can I Use These Membrane Products Outside the Van?

If a campervan patio or external retreat area is part of your build, you don’t need a separate indoor-only membrane system. The same geotextile fabric used inside a conversion can work outside, provided it is covered by a surface layer and fixed well.

Laying the membrane outside a campervan

Clear the area of loose debris and level the ground as much as possible. Roll the Groundtex Woven Weed Membrane 2m x 10m over the prepared surface, then secure it at intervals with fixing pegs before adding your surface layer. A 10-peg pack is usually the more economical choice for a full sheet, while single pegs can be useful for small areas or edge repairs.

When this matters

Outdoor ground next to a campervan is exposed to more weather, foot traffic and drainage pressure than an internal floor. A heavy-duty geotextile helps maintain a stable base and reduces the chance of weed growth disturbing the area. If the retreat area will be walked on regularly, anchoring the membrane with UV-stabilised pegs is a more practical option than leaving it loose.
