Are there any problems with Resin Bound Driveways?

Resin bound driveways are a popular choice for their aesthetic appeal, durability, and low maintenance. However, like any surface material, they can present certain challenges. Here's a breakdown of the common problems with resin bound driveways and how they can be addressed or prevented:

Poor Resin Bound Installation problems

Improper installation, such as incorrect mixing ratios or uneven application, can lead to weak spots, cracking, or a shorter lifespan. Therefore, it's crucial to hire experienced professionals with a proven track record in installing resin-bound surfaces. The installer must follow manufacturer guidelines for mixing and applying the resin and aggregate. Here are some problems that can occur if the resin bound gravel is incorrectly prepared or installed -

Water Pooling or Drainage Issues

Problem: If the driveway isn’t laid on a suitable permeable base or doesn’t comply with SUDS (Sustainable Urban Drainage Systems) regulations, water can pool.
Solution: Ensure that proper measures are taken during the preparation. For example, there are drainage channels under the surface so that the resin bound system is SUDS compliant, allowing the water to drain efficiently.

 Proper sub-base preparation is critical

Surface Cracking

Problem: Cracking can occur due to an unstable or poorly prepared sub-base or the use of low-quality resin.
Solution: Proper sub-base preparation is critical. The sub-base should be stable, level, and free of movement. Use high-grade resin for added flexibility and strength.

Loose Stones or Erosion

Loose Stones or Erosion

Problem: Over time, stones may come loose if the resin is applied too thinly or if poor-quality aggregates are used.
Solution: Use high-quality aggregates and ensure the resin is applied at the correct depth to fully encapsulate the stones.

Slippery Surface

Slippery Surface

Problem: A resin bound surface should not become slippery in icy or wet conditions.
Solution: Add anti-slip aggregates and ensure that crushed glass is applied to the surface during the installation process to enhance grip and safety.

Problems caused by using unsuitable materials

As well as problems with resin-bound driveways from poor installation, unsuitable materials are another source of problems. For example -

UV Discolouration

UV Discolouration

Problem: Some resins can discolour or yellow over time when exposed to UV rays. This is more common with non-UV-stable resins.
Solution: Use UV-stable resins that resist discolouration and maintain the surface's original appearance. Most high-quality installers offer this as standard.

Damage from Heavy Loads

Damage from Heavy Loads

Problem: Resin-bound surfaces may not withstand frequent heavy loads, leading to indentations or cracking.
Solution: Choose a driveway thickness and aggregate size suitable for the anticipated traffic. Crucially, we use a superior 20mm thickness of resin bound gravel for enhanced longevity and performance. For areas with frequent heavy vehicle use, consider additional reinforcement measures.

Inadequate maintenance

Whilst there's not much maintenance to do on resin bound driveways, it is worth mentioning some basic maintenance tips which will keep your resin bound gravel surface looking clean and pristine.

Weeds Growth

Weeds Growth

Problem: Weeds can grow on top of the surface but will not grow from underneath the surface if correctly prepared.
Solution: Maintain the surface by regularly cleaning it and, if needed, applying a weed killer to keep it in excellent condition.

Maintenance Tips

Maintenance Tips

Problem: Debris, dirt, and moss can build up, affecting the driveway’s appearance over time.
Solution: Regular maintenance, including sweeping and occasional power washing, will keep the surface looking clean and pristine. Avoid using harsh chemicals that could damage the resin.

Get peace of mind it's being done right

Most problems with resin-bound driveways stem from poor installation, unsuitable materials, or inadequate maintenance. Consequently, a quick check that the resin bound mix is UV stable in the sun and allows rainwater to drain away i.e. is SUDS compliant, is a good start. Remember, the substrate and drainage below the resin bound surface is of paramount importance and careful preparation, as in all landscape work, will determine a successful outcome. Crucially, checking out reviews and previous work ensures you are using an established and reputable installer that should readily provide quibble-free guarantees.

By working with experienced installers and following proper care practices, you can avoid these issues and enjoy a durable, visually stunning driveway for many years.
