The core difference: mixed together vs scattered on top
A resin bound surface is made by mixing washed, kiln-dried aggregate with a clear resin in a forced-action mixer, then hand-trowelling the blend onto a solid base at a typical depth of 15 to 20 millimetres for a driveway. Every stone is coated in resin, which is why the finished surface is smooth, tightly packed and porous, with thousands of tiny voids between the stones that let rainwater drain straight through.
A resin bonded surface works the other way round. A layer of resin is spread onto the existing base like an adhesive, and loose dry aggregate is scattered over the top before it cures. Only the underside of each stone is stuck down, so the finish is rougher, more like traditional gravel in appearance, and the surface itself is not permeable because the resin layer beneath is solid.
How each one performs on a driveway
For most driveways around Shrewsbury we recommend resin bound. Because the whole depth is bonded together it copes well with cars turning on the spot, resists loose stone, and its permeability means puddles and winter ice patches are far less of a problem. On heavy clay ground, which is common across Shropshire, that drainage matters more than people expect.
Resin bonded has its place too. The coarser texture gives excellent grip, which is why it is often used on slopes, ramps and footpaths. The trade-off is that stones do work loose over time, particularly where tyres scrub, so on a driveway you should expect some shedding and occasional patch repairs.
- Resin bound: smooth finish, permeable, roughly 15 to 25 year lifespan when properly installed
- Resin bonded: textured gravel look, not permeable, typically 8 to 12 years on a driveway before it needs attention
- Resin bound needs a sound base such as open-textured tarmac or concrete; bonded can sometimes go over a wider range of existing surfaces
Planning permission and drainage rules
Since 2008, paving over a front garden with an impermeable surface larger than five square metres needs planning permission unless the water drains to a permeable area. A properly installed resin bound driveway over a permeable base is a SuDS-compliant surface, so it normally avoids the need for a planning application altogether.
Resin bonded does not qualify on its own because the resin layer seals the surface. That does not rule it out, but you would need to direct run-off to a lawn, border or soakaway, or apply for permission. It is worth checking this before accepting a quote, because retrofitting drainage adds cost.
What each option tends to cost
Prices vary with access, the condition of the existing base and the aggregate you choose, but as a rough guide resin bound driveways in the Shrewsbury area typically come in between 60 and 110 pounds per square metre installed. If the existing tarmac or concrete is sound, you are usually at the lower end; if a new base is needed, expect the higher end or above.
Resin bonded is usually cheaper, often 40 to 70 pounds per square metre, because it uses less material and is quicker to lay. Over the life of the surface that gap narrows, since a bonded driveway is likely to need repairs or replacement sooner. Any quote should state the depth of the resin bound layer and whether the base is included, as that is where cheap quotes usually cut corners.
Which one is right for your home?
Choose resin bound if you want a smooth, low-maintenance driveway that drains freely, stays tidy and avoids planning complications. Choose resin bonded if you mainly need grip on a path or slope, want the loose-gravel look without the raking, or are working to a tighter budget on a lightly used area.
If you are unsure what your existing surface can take, a quick site visit settles it. The condition of the base decides more about how long either system lasts than the resin itself does.
