Resin Driveway in Merthyr Tydfil

While resin bound and resin bonded driveways have similar names, it might surprise you to know that they’re very different. Both paving systems use resin and aggregates (stones) to form a fixed surface, but there are plenty more differences than there are similarities.

Resin bound driveways are made from a resin and aggregate mix that is trowelled onto a bitmac or concrete base. It leaves a smooth, flat finish and you won’t find any loose gravel. It’s also a pourous surface, which means that rainwater can pass through into the ground, avoiding pools and flooding.

However, resin bonded driveways involve spreading resin across a base, then scattering aggregate into it. Most of the stones will stick to the resin, but some will stay loose. That means you’ll get the effect of loose gravel without so much to sweep and take care of. Because the stones are scattered onto a complete layer of resin, water can’t pass through it. That means you could end up with water pooling, and it also means that a resin bonded driveway isn’t frost resistant, meaning it could get slippery.

So which is better – a resin bound or resin bonded driveway? The answer depends on a few things. If you have a period property where a smooth, shiny surface might not complement the look of your home, you might want to go for resin bonded. If you need lots of grip, for example if you’re a wheelchair user, resin bonded may also be the way to go – even though resin bound surfaces still offer enough grip for sloped driveways and ramps. But if you want a low-maintenance, weed-free, permeable surface, resin bound driveways are the way to go.

Resin bound driveways are known to last a long time without the need for repairs, but sometimes accidents happen. You also need to make sure you regularly maintain your driveway by sweeping and power washing it to prevent damage. But if it does get damaged, how do you repair your resin bound driveway?

If you notice a crack in your resin bound driveway, it’s important to repair it as soon as possible. If you leave it to erode, you could end up with a difficult repair that will cost much more money.

To repair a crack, you’ll need to carefully chisel it open slightly so you can apply a primer then fill in the crack with a matching-coloured resin and aggregate mix. While there are variations in colour and size with all stone mixes, usually it’s easy to find a batch that matches almost perfectly. And once the crack has been repaired for a while, it will blend in seamlessly with the rest of your driveway.

To prevent cracking in your resin bound driveway, it’s best to tackle the issue at initial installation. Speak to your installer about whether it’s possible to add fibreglass mesh to the base. You should also ask your installer to add expansion trims as these will significantly reduce the risks of cracks.

So the best way to repair resin bound driveways is to prise open the crack and fill it in. It might seem simple, but getting the right colour match is something that should be left to the professionals, so get a few quotes to ensure you get the best finish.
