Resin bound is now one of the most asked-about driveway finishes around St Austell, and the first question is almost always the price. The honest answer is that it depends heavily on what is underneath your existing drive, how much digging is needed and how big the area is. This guide sets out realistic figures for the St Austell area and explains what pushes a quote up or down.
For a straightforward job in the St Austell area, most homeowners should expect to pay somewhere between £65 and £110 per square metre for resin bound laid onto a suitable new base. That figure covers the base build, the resin and aggregate, edging and labour. A typical two-car drive of around 40 to 50 square metres therefore tends to land between £3,500 and £6,000, with larger or more awkward drives going higher.
If you already have a sound tarmac or concrete surface in good condition, the resin can sometimes be overlaid directly. That brings the cost down to roughly £45 to £70 per square metre because the groundwork is minimal. Very few older drives in St Austell qualify, though. Many were laid on thin or patchy bases years ago, and resin only lasts as long as what sits beneath it.
The biggest cost variable is groundwork. Removing an old block paved or concrete drive, digging out to the right depth and installing a compacted sub-base and permeable tarmac or concrete binder course is where most of the money goes. Around St Austell the ground can be heavy clay or sit over old mine workings and china clay waste, so a decent contractor will want to see what is below before pricing.
Access and waste matter too. Narrow lanes in villages such as Charlestown, Mevagissey or St Blazey can rule out large tippers and grab lorries, which means more hand digging and smaller loads. Drainage is another factor: if the drive falls towards the house or the road, you may need a linear channel or soakaway, which can add several hundred pounds.
Finally, the resin system itself. UV stable resin costs more than standard but will not yellow in the sun, which is worth paying for on a south facing drive. Decorative aggregate blends, borders in a contrasting colour and curved edges all add labour and material cost.
Resin bound is permeable when laid on a proper open graded base, which is why it suits Cornish properties well. Under the national permitted development rules, a new or replacement front drive over five square metres must either be permeable or drain to a lawn or border within your own boundary. A true resin bound system on a permeable sub-base normally satisfies this without needing planning permission from Cornwall Council.
Be careful with cheaper quotes that describe the job as resin bonded rather than resin bound. Bonded is a thin scatter of stone over resin and is not permeable, so it can trigger the planning requirement and tends to shed stone within a few years. Ask which system is being quoted and what the base build up is.
If your home is in a conservation area, for example parts of Charlestown or the older streets around Holy Trinity in St Austell, it is still worth a quick check with the council before you start, particularly if you are altering a front wall or dropped kerb.
Three quotes for the same drive in St Austell can easily differ by a couple of thousand pounds, and the cheapest is rarely the best value. The difference is almost always in the base. A drive priced on 150mm of compacted sub-base with a tarmac binder course will cost more than one laid directly onto compacted stone, but it will not crack, sink or lift when a delivery van turns on it.
Ask each contractor to break the quote down into excavation, sub-base, binder course, resin layer, edging and drainage. Check the resin thickness, which should be 15mm to 18mm for a driveway rather than the 12mm used on paths. Ask what guarantee is offered on the groundwork as well as the surface, because a surface warranty is worthless if the base fails underneath it.
A groundworks firm that also handles drainage, kerbs and dropped crossings can often save you money by doing the whole job in one visit rather than bringing in separate trades. It also means one point of responsibility if anything needs attention later.
On a like for like base the finished price is usually similar, with resin often slightly dearer per square metre but quicker to lay and easier to keep weed free. Block paving tends to be cheaper only when the groundwork is minimal.
Most residential drives around St Austell take three to five working days, with the resin itself going down in a single day once the base has cured. Wet weather can delay the resin layer because it needs a dry surface.
Sometimes, if the concrete is sound, well drained and free of major cracks or movement. A contractor should inspect it first, and if it is breaking up or sits on a poor base, a full dig out will give a far longer lasting result.
