Resin Driveway in Amersham

A resin bound driveway is made from resin and aggregates that are mixed together to create a smooth, flat surface. They’re often called ‘stone carpets’ because they offer a decorative finish that is durable and requires very little maintenance. It has lots of little gaps that allow water to drain into the ground, which means that you won’t get pooling or flooding around your property.

You can choose from lots of different colours and types of aggregate (stones) so that your resin bound driveway complements your property. Most contractors recommend choosing a darker aggregate because they are more resistant to the sun, but if you choose a good UV-resistant resin you should be able to have a lighter stone that doesn’t get too bleached by the sun.

To lay a resin bound driveway, resin and aggregates are mixed in a forced action mixer to create a mixture that a tradesperson will then pour and trowel onto a prepared base. It will become smooth once it’s cured, and the stones will all be contained, so you won’t have to spend time sweeping gravel back onto your driveway. The only maintenance that’s needed is to wash it with soapy water every now and again and sweep away any debris. Just make sure you don’t use chemicals or oils, as this might damage the coating.

1. Prepare the base If you want your resin bound driveway to last a long time, you need to ensure that you prepare the base properly. Remove any block paving, grass or soil and dig down until you hit solid ground. Lay a sub-base of asphalt for good permeability. If you’re laying over the top of your current driveway, make sure that all cracks are increased into a ‘v’ shape with a saw and ensure the surface is dry and weed-free.
2. Mix the resin You must follow the instructions on the materials you have to the letter if you want the curing process to work. Usually batches come in ‘Part A’ and ‘Part B’. Keep the resin container secure and on a protective surface to avoid splashing, then mix Part A for 10-20 seconds at a slow speed with a helical bladed mixer. Add Part B and mix thoroughly at a slow speed for about 2 minutes until it’s blended together.
3. Mix the dried aggregates and sand with the resin Place a quarter of the aggregates into a mixer, then add the pre-mixed resin and start a stopwatch. You should then add the rest of the aggregates before slowly adding the sand. When you’re happy with that mix, stop the stopwatch. That time is the time that you need to spend mixing any other resin and aggregates to avoid colour variation.
4. Lay the mix on the surface Transfer the mix to the work area then plan a laying route. When the mix is laid out, use a very clean trowel to spread the mix. Clean it regularly during the process to avoid dragging aggregates out of place. Once the aggregates stop moving in a fluid movement and become solid, stop trowelling. Then you can polish the surface to give it an attractive shine.

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.
