Resin Driveway in Portland

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.

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.

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.
