SWINDON, 8 September 2026 – The heavy clay beneath much of Swindon could be playing a bigger role in damaged driveways than many homeowners realise. Local installer RPS Resin Driveways says the town’s changing ground conditions can contribute to cracked concrete, sinking block paving and deteriorating tarmac. The company has released free homeowner guides explaining how Swindon’s soil affects driveways, how much replacement work can cost and which local planning requirements need to be considered.
The timing is deliberate. Autumn is when the clay beneath the town begins absorbing moisture again following the summer’s drier conditions, making existing cracks, movement and dips particularly noticeable.
“People assume a cracked driveway means someone did a bad job,” said James, who runs RPS Resin Driveways. “Sometimes that’s true. But in Swindon the ground itself is the problem. The clay under Stratton, Walcot, Toothill, Freshbrook and most of the newer estates swells when it’s wet and shrinks when it’s dry, and it does that every single year. A rigid slab of concrete has no way to cope with that.”
Clay shrinkage is the most common cause of subsidence claims in the UK. Houses are built on foundations designed to deal with it. Driveways are not. They sit a few inches into the ground, right in the layer that moves.
What a driveway on clay actually needs
According to the company, the material chosen for the visible driveway is only part of the equation. Its guidance on resin bound driveways in Swindon recommends between 100 and 150mm of compacted, permeable stone beneath the finished surface. This allows rainwater to drain away instead of remaining against the clay and contributing to further movement.
“The quote that’s a thousand pounds cheaper is nearly always cheaper because the sub-base is thinner or missing,” James said. “You won’t see the difference on the day it’s finished. You’ll see it two winters later. Any installer quoting in this town should be able to tell you exactly how deep they’re digging and what they’re putting back in. If they can’t, walk away.”
The firm has completed more than 800 resin installations throughout Swindon and surrounding Wiltshire towns. It offers a 10-year workmanship guarantee and a separate 15-year guarantee covering the resin system.
Three rules that catch Swindon homeowners out
The company’s guides also explain the permissions homeowners may need before work begins. James says paperwork can cause more delays than the weather.
Since October 2008, homeowners who pave more than five square metres of front garden with an impermeable surface have needed planning permission. Permeable options, including resin bound stone installed over a free-draining base, are exempt. Homes within Swindon’s conservation areas, including parts of Old Town and the Railway Village, may still require consent.
Changing the kerb is a separate matter and requires its own application. Swindon Borough Council charges £203 for a residential vehicle crossing licence. The fee is not refunded if an application is refused. The driveway must also measure at least five metres from the rear of the pavement to the property and 2.5 metres in width before the council will consider the application. Kerbs on the public highway can only be altered by an appropriately licensed contractor.
Resin bound surfacing also has weather limitations. It cannot be installed during rain or when the ground is close to freezing. Homeowners wanting their driveway completed before Christmas therefore need to arrange the work by around mid-autumn.
What it costs
The company’s published guide prices put resin bound surfacing at approximately £100 to £300 per square metre. For most Swindon properties, total costs generally fall between £2,500 and £12,000 once preparation and groundwork are included.
The existing driveway can make a significant difference to the final bill. A solid concrete base may sometimes provide a suitable foundation for an overlay, whereas a failed block paved driveway sitting on wet clay can require complete excavation and reconstruction. The company’s resin driveway cost guide provides further figures based on driveway dimensions and existing surfaces.
“Honestly, I’d rather someone read the guides and got a fair job from a competitor than paid us without understanding what they were buying,” James said. “The town has enough driveways that failed inside five years. We’d like fewer of them.”
