Resin bonded and resin bound surfaces are both types of resin driveways, but they differ in their application, finish and uses. In general, resin bound surfaces are a better choice for where good drainage is required and for those who want a smooth, modern appearance. Resin bonded surfaces are a good choice for areas where a rougher gravel texture is needed or desired.
The differences…
What is a resin bonded driveway?
With resin bonded driveways, a layer of resin is applied to an existing surface such as tarmac or concrete, and then loose gravel/ aggregate is scattered over it. This gives it a rough textured, anti-slip surface.
Installation costs are generally cheaper due to the lower level of groundworks required, but the surface requires more maintenance over time dealing with gravel that comes loose. And unlike resin bound surfaces, a resin bonded driveway is not permeable so drainage may be an issue.
So what does resin bound mean?
On the other hand, resin bound systems involve mixing the resin with the aggregate before application. The resin completely binds the gravel for a smooth finish, and the permeable nature of a resin bound surface ensures good drainage. Because of this, you are less likely to need planning permission as they are SUDs compliant.
Most people find resin bound driveways more aesthetically pleasing, and they require less maintenance than their resin bonded cousins. However, they are more expensive than a resin bonded driveway due to the more extensive groundworks, and also less suitable for steeper slopes and drives. Even with the application of an anti-slip top coat to a resin bound surface, the looser, rougher gravel finish of a resin bonded surface will afford better grip.
So which should I choose? Resin bound or resin bonded?
| Feature | Resin Bonded | Resin Bound |
|---|---|---|
| Appearance | Rougher texture | Smooth texture |
| Permeability | Not permeable | Permeable |
| Grip | Good grip | Less grip |
| Durability | Highly durable | Durable |
| Maintenance | More maintenance | Less maintenance |
| Cost | More affordable | More expensive |
There are pros and cons, but we would almost always recommend a resin bound gravel surface over a resin bonded one. They look nicer, they’re less maintenance, and you don’t need to worry about drainage. But there are occasions where a resin bonded surface, or another finish like tarmac might be more suitable, for example on sites which experience heavy traffic, or have heavy vehicles parked in the same spot for long periods, and for sloping sites that need good grip.
