Resin Driveway in Gwynedd

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.

Whether you think resin bound driveways are expensive or not will depend on your perception. While resin bound driveways are the most expensive up front, they should last much longer than other types of driveway. You should expect a resin bound driveway to last at least 25 years, if not longer, while a concrete or asphalt driveway may last between 15-20 years. A pattern imprinted driveway may last even less time due to the maintenance required to keep them looking pristine.

It’s also worth considering that resin bound driveways are good permeable surfaces, so will drain well and keep water from pooling around your property. This will keep your property maintenance costs down, since pooling water or flooding around your home could cause damp in your walls which is a very expensive problem to fix.

Resin bound driveways are by far the most attractive type of driveway to have. There are no loose stones to sweep up, no weeds to pull out from the gaps, and there’s no extensive power washing required to keep them looking good. If you want a driveway that gives your home true kerb appeal and you value your time, resin bound driveways don’t seem that expensive.

The other factor that can make resin bonded driveways less expensive is that sometimes you can lay them on top of the existing surface. For example, if you already have a concrete or asphalt driveway that is in good condition with no large cracks, a driveway contractor may be able to lay the resin and aggregate mix straight over the top, which will cost much less money than if you have to dig up the existing driveway and start from scratch.

The best way to clean resin bound driveways is to sweep it regularly with a stiff broom. This will remove any debris and prevent moss from growing. It's a good idea to jet wash it after sweeping, because this will get rid of any smaller parts that a broom might not collect.

When you jet wash or power wash your resin bound driveway, make sure the pressure isn’t too high. It’s recommended to keep the pressure less than 150bar, as anything too strong could damage the surface. Make sure the water is cool, but not cold – both hot and cold water can damage the resin. Make sure the jet wash nozzle is at least 20cm from the surface. Any closer and this could damage your driveway. Use a sweeping back and forth motion to clean.

If you treat the area before you have your resin bound driveway installed, you shouldn’t get any weed growth. But if you get any moss or algae appear, you can apply a moss and algae killer that should remove and prevent any regrowth. If you have ingrained algae, you can remove it with a strong bleach solution; make sure you follow the manufacturer’s instructions. This should also help restore the driveway’s original colour. Make sure you rinse your driveway thoroughly with clean water after using bleach on it to prevent any harm to wildlife or plants.

If you get chewing gum on your resin bound driveway and you can’t get it off with a pressure washer, try using a freezing spray on it first. Then use a wall scraper to gently remove it – never dig under the chewing gum as this could damage the resin on your driveway.
