Barbed Ground Pegs for Soil and Compacted Sub-Base

How the barbed profile increases grip

The grip comes from the small ridges or barbs moulded along the spike. As the peg is pressed or tapped into the ground, the barbs push against the surrounding soil or compacted sub-base. Once in place, they resist upward movement, helping the peg stay seated while the geotextile is pulled flat.

This is a temporary mechanical fix rather than a structural anchor. In resin bound driveway work, the peg is there to hold the membrane in position before the main surface is poured, not to carry load afterwards.

Where barbed pegs are most useful

Barbed ground pegs are most useful in firm ground conditions, such as compacted MOT type sub-bases, hard ground, or dense soil. They are designed to work with woven and non-woven geotextile membranes used beneath resin bound driveways.

When selecting pegs, look for weather-resistant material if the fixing will be left in place outdoors. The Weed Membrane Fixing Peg, for example, is sold as a single peg or a multi-peg pack, making it easier to buy enough for a larger area without over-ordering.

Simple installation tips

Secure the membrane before pouring so it cannot lift or fold. A straightforward method is:

• Lay the geotextile flat over the prepared ground, leaving enough overlap at edges and joints.
• Push or lightly tap the peg through the membrane into the soil or compacted sub-base.
• Space pegs at regular intervals, adding extra near overlaps and corners.
• Check the membrane remains taut and re-fix any areas that have lifted.

If the ground is particularly hard, pre-punching a small pilot hole can help avoid bending the peg, though this may not be necessary where the barbed profile can still bite.
