Resin Bonded or Resin Bound Driveways: Key Differences

Resin Driveways Explained

Many people assume that resin driveways are all made in the same way. For many homeowners across the Thames Valley, resin surfacing might seem somewhat standard. The reality is very different.

Resin drive surfacing is a type of fixed surfacing which combines a mixture of both resin and aggregates. You may have heard the terms ‘resin bound driveway’ and ‘resin bonded driveway’ thrown around. Despite the names of these surface materials sounding very similar, they are substantially different. 

This blog will outline the fundamental differences between resin bound and resin bonded systems. To help you make the right choice for your property, and to give you some clarity on the two surface types, it’s essential to understand what primarily separates a bonded system from a bound system.

What is a Resin Bound Driveway?

Installing resin bound driveways involves laying a hard-wearing course of mixed resin onto an existing or fresh base. The dried aggregates are mixed with the resin and subsequently trowelled onto the base, creating a smooth finish.

What is a Resin Bonded Driveway?

Resin bonded driveways are systems where the aggregates are loosely scattered across the resin after it’s spread across the base. The majority of the time, the aggregates adhere to the resin, but there does lie a possibility that some will be loose. 

In terms of how the driveway systems are installed, there are some other differences between these two surfaces. One of the most common questions asked is whether one is better than the other. Hopefully, if you are currently deciding on new driveway options for your property, the below will help you understand. 

Differences between Resin Bonded and Resin Bound Driveways


Perhaps the most significant difference is that resin bound driveways are completely permeable and SUDS (Sustainable Urban Drainage System) compliant. The increased risk of flooding caused by urbanisation means that all new driveway designs have to comply with SUDS regulations. Therefore any resin bound system does not require any planning permission, as long as the sub-base is porous, or that there is a suitable soakaway.

Resin bonded driveways, unfortunately, are not porous, nor are they SUDS compliant. This is because aggregates are scattered onto a complete layer of resin (rather than mixed directly), meaning that water cannot adequately pass through. However, resin bonded pathways are still cost-effective ways to create beautiful spaces, as they are still attractive, non-slip, visually stunning solutions.


Typically speaking, a resin bound path is installed in thicknesses ranging from 15-25mm. With bonded systems, the thin layer of resin stands approximately 5mm thick. Depending on the aggregate size, it won’t likely achieve the same thickness as a resin bound driveway.


Resin bound drives often use a combination of at least 2 classes of aggregates, in different sizes. For example, it can include a mixture of both 2-5mm and 1-3mm sizes. Whereas a resin bonded driveway typically uses one size aggregate grade, usually 1-3mm. 


As far as resin bound driveways pros and cons are concerned, one of their most significant benefits is the fact that they are resistant to almost anything. When installed correctly, they are resistant to weeds, frost and slipping. Luckily, resin bonded stone driveways are much the same, but due to their application method, they are not impervious to frost. 

Both driveways will succumb to damage if heavy vehicles or sharp edges stay on the surface for too long. However, they can be maintained relatively easily.

Colour retention

There are numerous resin driveway colours and designs to choose from, meaning that you can usually find a colour mixture that will suit your style and property. It’s fair to say that resin driveways will retain their colour for a considerable time. Of course, regular maintenance and upkeep will undoubtedly improve their longevity and durability.

Which Driveway is Best for Me?

If you’re a homeowner in the Surrey or Berkshire area and are looking for a porous surface, that is aesthetically-pleasing, easy to take care of and will stand the test of time, you may want to consider a resin bound driveway.
