Bound Gravel is a high-performance SUDS compliant, porous aggregate bound system.
Available in a range of colours and blends, the gravel surface is extremely hard wearing and provides visually stunning finishes. Unlike block paving, bound gravel is slip-resistant, weed resistant, and does not sink under extended use. This makes it the ideal, low-maintenance surface for driveways, pathways and walkways.
Resin Bound Gravel is applied using your choice of coloured gravel aggregate. It is bound together with resin to form a smoother natural appearance when compared to loose gravel. Coloured gravel can be used to incorporate graphics and designs or to match exterior masonry. After months of testing the BBA have endorsed the system for its high strength, SUDS compliance, and its excellent track record.

HOW WE LAY BOUND GRAVEL
Bound gravel can be installed onto min 50mm AC14 open texture binder course.
Step 1Whilst on site we mix 1-3mm or 2-5mm aggregate with a resin binder. |
Step 2The mixture of aggregate and resin is levelled to the required thickness. A screed or hand trowel is used to smooth and lightly compact the gravel to gain an even, level finish. |
Step 3The surface will be ready to use the following day. |

FREQUENTLY ASKED QUESTIONS Q. Resin bound and resin bonded – What is the difference? A. Bound: Aggregate is mixed with resin in a mixer and then hand-trowelled into place to produce a surface that is smooth and porous. Porous resin bound surfaces perform better than non-porous resin bonded ones, allowing drainage of surface water and better environmental compliance. Bonded: A layer of resin is screeded onto a surface and then a fine aggregate is scattered over the top and rolled in. This produces a rough surface that is not porous. Q. Will the surface always be porous? A. As with all new surfacing, maintenance is key. Resin drives should be swept regularly of leaves to avoid a build-up of debris. Q. What can resin bound surfacing be laid on? A. Resin bound surfacing can be installed onto min 50mm AC14 open texture binder course. Q. Is resin bound surfacing strong enough to take vehicles? A. Yes, the stone and resin used is extremely hard-wearing, so it can be used by vehicles. Q. What size aggregate is used for the resin bound surfacing? A. Normally a 1-3 / 2-5mm sized aggregate would be used for a driveway, terrace or path. This ensures that the internal makeup of the surfacing is a tight, well-bound mixture, with the right amount of cavitation for permeability. This would be laid at min 20mm depth for a driveway, and min 16mm for a path or terrace. For tree pits, we would recommend a 5-8mm or 10mm sized aggregate to achieve optimum strength and porosity. Q. What will happen to resin bound surfacing during times of extreme heat or freezing? A. As the resin bound surfacing has cavitation within the mixture, water will run through the surface and back into the ground. This stops water from pooling on the surface, so causing a freezing problem. During times of extreme heat the resin bound surface will remain cooler than asphalt or concrete, due to the cavitation allowing air to circulate through it. |
