Block paving was once the go-to surface for homeowners across the UK, but resin bound has been gradually catching up. Easy to maintain, unlimited design options, more affordable, with all its benefits, it’s clear to why thousands are opting for it.
With those updating to this versatile material from block paving, one of the questions we get asked most is “can resin bound be laid over block paving?”. In this article, we answer that question conclusively.
Laying Resin Bound Over Block Paving
Although it’s possible to lay resin bound over block paving, it’s certainly not a good idea. Block paving isn’t a solid enough base, as over time, they shift and settle. They’re created by combining hundreds of different bricks and paving slabs, and if just one or two of them move (as they’re prone to doing over time), it’s bad news for your new resin bound driveway.
Sufficient movement is likely to lead to sinking or cracking, both of which will be expensive to repair. And once you repair it, it’s quite possible that the same issues will reoccur over time. If you’re going to resin bound your outside area, driveway, garden path, or patios, it’s best to do it right the first time, ripping up the block paving and putting down a suitable base in its place.
What Surfaces Can You Lay Resin Bound Over
You can lay resin bound over any existing concrete, tarmac, or asphalt surface, as long as they’re in good condition. Resin bound is just a thin layer, typically 15–18mm thick, so is simply laid over your existing surface. The only preparation needed (if your surface is in good condition) is making sure it’s clean, dry, and free from any loose material or debris before installation. Loose materials like gravel, sand, or damaged surfaces will impact the quality of finish, and risk issues occurring over time.
If your existing surface is damaged, uneven, or made from unsuitable materials, you’ll need to either get it repaired first or rip it up entirely and put down a proper sub-base instead.
Best Sub Bases for Resin Bound Surfaces
The most commonly used materials for sub bases of resin bound surfaces are concrete, tarmac, and asphalt. These all provide a solid base that resin bound surfaces need to last. Grid systems are also a great option, though requiring more resin, cost more.
Granular sub-bases made from gravel or sand may come to mind but aren’t suitable. This is down to damp that could come up from underneath over time, seeping into the resin, affecting the product.
Timing is important with sub bases. Whatever material you choose needs to be left to cure fully before the resin bound surface goes on top. For tarmac or asphalt bases, you’re looking at a minimum of two weeks to set properly. Concrete, however, can take up to a month to fully cure, which might make it less appealing if you’re eager to get your new surface down. Grid systems remove the need for curing, which may make it a more suitable option.

Final Thoughts
Laying resin over block paving has a lower initial cost than installing a new sub-base, but it’s less likely to last. Block paving is made up of hundreds of bricks and paving slabs that can shift and settle over time. Even a small amount of movement can damage the resin surface. Resin-bound paving can be (and should be) laid on solid surfaces like concrete and tarmac, as long as they are load-bearing and not likely to crack.
