Resin-bound stone is naturally permeable — water drains through the surface to the substrate instead of pooling or running into the street. SuDS-compliant, meltwater won't freeze on the surface, and there's no need for drains or grading adjustments.
The key difference between resin-bound stone and a solid surface like concrete or asphalt is the gap between aggregate particles. In a resin-bound system, every stone is coated in resin but the spaces between them remain open — water passes through to the base layer and soaks into the ground below.
This matters most where municipalities charge for stormwater run-off, where driveway pooling creates ice hazards in winter, and anywhere you want to keep water on your property instead of sending it to the street. Resin-bound permeable paving eliminates the need for drains, catch basins, or grading adjustments on most sites.
Same path, same grade — the difference is a permeable surface that lets water pass through instead of pooling on top.
Meets Sustainable Drainage Systems standards for permeable paving — reduce or eliminate municipal drainage charges.
Meltwater drains through instead of pooling and freezing. No black ice, no salt rings, no slip hazard.
Because the surface drains itself, there's no need for trench drains, catch basins, or grading adjustments on most sites.
Common questions
Yes. A correctly installed resin-bound surface drains at over 1,000 litres per minute per square metre — well in excess of what even peak Toronto storms can deliver. The bottleneck is the substrate, which we always verify on-site before quoting.
Some Ontario municipalities (and condo corporations) offer drainage credits or rebates for permeable surfaces. Programmes change frequently — we can supply install documentation so you can apply for whatever is current in your area.
Routine sweeping and a hose rinse a couple of times a year keeps the surface clear. If heavy silt accumulates, a reverse rinse with a garden hose restores the original permeability.
Usually not. Because the surface drains through itself, most jobs don't need trench drains, catch basins, or extensive grading. We always confirm substrate drainage during the on-site quote.
No — permeable drainage is what prevents that. Water drains through to the substrate instead of pooling on the surface where it could freeze and heave the finish. Freeze-thaw rated for Canadian climate.
