Specially formulated and designed specifically for use in resin bound gravel surfacing, PermaPave’s standard aromatic UV stable polyurethane resin is perfect for mixing with decorative kiln-dried aggregates to create a continuous, permeable and attractive stone carpet surface.
SuDS compliant, resin bound gravel allows water to pass through the upper surface, and when installed over a permeable paving grid, water can drain freely into the ground, reducing the risk of surface water build up or flooding.
Typically combined with around 100kg of washed and dried gravel, and in some cases sand, this two-part polyurethane resin will form a sticky mix which can be mixed in a forced action mixer, ensuring that the components are mixed consistently and evenly.
We recommend that the 6.5kg resin binder should be combined with the following materials:
3x 25kg 2-5mm washed and kiln-dried aggregate
1x 12.5kg 1-3mm washed and kiln-dried aggregate
1x 6.25kg C52 sand
