How resin-bound works
Dried natural aggregate is mixed with a two-part polyurethane resin on site and trowelled to a smooth, even layer. Tiny voids between the stones let water drain straight through. Done properly, there is no loose gravel to scatter and no puddles on the surface.
Be wary of resin-bonded systems, where stone is scattered onto a layer of resin. They look similar on the first day but are not porous and can shed stones.
A base that lets water through
Because the whole point is drainage, the layer beneath must be permeable too. That normally means porous asphalt or a no-fines concrete over a compacted, open-graded stone sub-base. Overlaying an old impermeable concrete drive simply moves the puddle underneath, so we only overlay where the existing surface is sound and can drain.
Colours for York
Warm golds, buffs and bronze blends complement York's brick houses, while silvers and greys suit render and newer homes. A UV-stable resin stops pale blends discolouring. We often frame resin with a clay or granite sett border to give a crisp edge and a link with the house.
Laying and curing
Resin needs a dry day and a dry base. York weather doesn't always oblige, so dates can shift. Once cured, the drive is low maintenance: a sweep and the odd wash keep it looking smart.
