Resin bound vs resin bonded, what's the difference?

Question

We've had three quotes for the front drive and the cheapest turns out to be resin bonded rather than resin bound, it's around 50 square metres, does it really matter which we go with?

Resin bonded wouldnt last as long as resin bound , resin bound allows water to escape better , where as resin bonded lets water sit on top of surface and runs off if that makes sense  and can get patches over time , personally I’d go for  resin bound , its more expensive but probably worth it in the long run , hope this helps

Resin bound: The stone and resin are mixed together before being laid onto a prepared base. This creates a smooth, even finish with small gaps that let water drain through, provided the base is permeable too.
Resin bonded: A layer of resin is applied to the base and loose stone is scattered over it. This gives a rougher, more textured finish. The surface is generally impermeable, so water needs to drain away across it.
For a driveway used regularly by cars, I would generally recommend resin bound. The stones are held together throughout the mix, so there’s less risk of loose stone over time, and the smooth surface is easier to sweep and maintain. Its permeability can also help reduce puddles and surface runoff when it’s installed over a suitable base.
The lower price of resin bonded may be appealing, but it’s worth comparing what each quote includes, especially the base preparation, drainage, finish and guarantee. The right choice for your 50m² driveway will depend on the existing surface and how each contractor plans to prepare it.

Yes, it does matter. Although the names sound similar, resin bound and resin bonded are very different surfaces.
Resin bound is the premium option and is what most people mean when they ask for a resin driveway. The aggregate is mixed with the resin before being laid, creating a smooth, permeable surface that is durable, low maintenance and suitable for vehicles.
Resin bonded involves the resin being applied to the surface first and loose aggregate scattered on top. It gives the appearance of loose gravel but can shed stones over time, is not generally permeable, and is typically used for pathways or decorative areas rather than driveways.
For a 50m² front drive, we would usually recommend resin bound. While the initial cost is higher, it tends to provide a better finish, longer lifespan and lower maintenance requirements.
Before making a decision, it’s worth checking exactly what base preparation each quote includes, as this can have a significant impact on both performance and longevity.

Yes, it matters a lot, as their technical properties are different.
Resin Bound,the aggregate is fully mixed with the resin .
Resin Bonded: Resin is spread over the surface,the surface is impermeable.
Resin Bound is the superior long-term option, even if it is more expensive

Drew · Answer

Resin bound the Stones get mixed together so all stones are coated resin bonded the stones get coated on after a cheaper option but not as long lasting

Andrew · Answer

I personally dont think theres to much differerance ,there both fine if its preped & layed correctly

Michael · Answer

Yes, there’s quite a difference. Resin bound is generally the better option for a driveway – the stone and resin are mixed together and laid as one surface, so it’s smoother, more durable and porous when installed correctly. Resin bonded is basically resin spread onto the base with aggregate scattered over it, so it can loosen over time and isn’t permeable. The cheaper quote may be cheaper for a reason, so make sure you’re comparing like for like.
