Resin Bound Driveways Questions

Most failures trace back to an inadequate sub-base. If the base moves, settles, or holds water, the resin layer above will crack or delaminate. UV-stable resin grades resist surface yellowing; non-UV-stable products discolour over time. Poor mixing ratios or laying in cold, wet conditions also cause premature failure.

An unsuitable base will cause the resin surface to crack, sink, or separate within months. The resin layer itself cannot compensate for movement below it. Remedying this after installation means breaking out the surface and starting again, which costs significantly more than addressing the base correctly at the outset.

Ask for the quote to itemise excavation, sub-base depth and specification, drainage provision, resin and aggregate type, surface depth in mm, and edging. A quote that bundles everything into one line makes it hard to compare. Our partners provide a full quote covering all of those elements after a site survey.

The main cost drivers are driveway size, depth of excavation needed, sub-base condition, drainage requirements, and aggregate choice. Decorative or larger-stone aggregates cost more than standard blends. Access constraints that slow installation also add to labour time. Most resin bound driveways in Cambridge come in at around £6,800, depending on these factors.

It depends on what is already there. A sound, well-drained concrete or tarmac base may need only minor preparation. A failing base, soft ground, or poor drainage will require excavation and a new MOT Type 3 or porous asphalt sub-base, which adds to the overall cost. A site survey confirms this before you commit.

Yes, in many cases resin bound can be laid directly over an existing surface, provided it is structurally sound and level. Cracked, sunken, or unstable surfaces need remedial work first. A site survey will confirm whether your existing drive is a suitable base or needs attention before installation.

Yes. Resin bound is a fully permeable surface, so rainwater drains through the material itself rather than running off the edges. This makes it suitable for most residential properties and means it meets SUDS requirements without needing additional drainage in most cases. See Permeable Driveways for more detail.

Yes. A correctly installed resin bound surface on a sound sub-base handles daily car traffic without issue. It resists tyre scuffing and point loads from standard vehicles. Heavy vehicles such as vans or skips can cause indentation if the base is not specified to handle that load.

Resin bound produces a flat, smooth, tightly bound surface with a consistent finish. Aggregate stones are fully encapsulated in resin, so there are no loose pieces. The finished depth is typically 15-18 mm, giving a clean, low-profile edge that sits neatly against kerbs and borders.

Clay ground moves with moisture changes, which can stress any surface above it. A correctly specified sub-base, typically 150 mm or more of compacted MOT Type 3, isolates the resin layer from clay movement. Without adequate sub-base depth, clay shrinkage and frost heave in a Cambridgeshire winter will cause cracking.

No, they are different products. Resin bound mixes aggregate and resin together before laying, creating a permeable, smooth, stone-encapsulated surface. Resin bonded applies resin to the base first, then scatters loose stone on top, leaving a rougher texture and a non-permeable finish that can shed stones over time.

Tarmac is a solid, impermeable black surface that sheds water to the edges. Resin bound is permeable, available in a wide range of aggregate colours, and produces a decorative finish. Tarmac is generally lower cost; resin bound costs more upfront but requires less maintenance and meets SUDS drainage rules. See Tarmac Driveways for a direct comparison.

Loose gravel shifts underfoot, scatters onto lawns, and needs regular raking. Resin bound uses the same stone types but binds them in resin, so the surface stays fixed, smooth, and weed-resistant. Both are permeable, but resin bound needs far less ongoing maintenance. See Gravel Driveways for more.

Repair makes sense for isolated damage on an otherwise sound surface. If cracking, sinking, or drainage problems are widespread, resurfacing with resin bound is usually more cost-effective long term. A site survey will identify whether the base is salvageable or needs full replacement before a decision is made.

Yes. Water passes through the resin bound surface and into the sub-base below rather than running off into drains or neighbouring land. This reduces surface pooling and lowers the load on local drainage systems. It is one reason resin bound meets SUDS requirements without additional drainage in most standard installations. See Driveway Drainage & Channel Drains if your site has specific drainage challenges.

Not always. If your existing surface is solid, well-drained, and level, resin bound can go straight over it. If it is cracked, lifting, or poorly drained, excavation and a new sub-base will be needed. A survey before work starts will confirm which approach applies to your drive.

Maintenance is minimal. An occasional jet wash removes dirt and algae, and a weed killer applied once or twice a year prevents growth in the joints. Unlike block paving, there is no sand to re-point and no individual units to lift and relay. Most surfaces stay presentable with one thorough clean per year.

A pressure washer on a medium setting removes most dirt, moss, and algae effectively. For oil stains, a degreaser applied before washing gives better results. Avoid high-pressure lances held close to the surface, as sustained pressure can dislodge aggregate from the edges of any worn areas.

Most resin bound surfaces are ready for foot traffic within a few hours of laying. Light vehicle use is typically possible after 24 hours, and full cure for regular parking is usually reached within 72 hours. Cold or damp weather slows curing, so your installer will confirm the exact wait time on the day.

Sometimes, but only if the existing base is sound, level, and draining correctly. A cracked or moving base needs repair or replacement first. The site survey confirms which applies before any material is ordered or priced.

A base that is already cracking or moving will worsen over winter. Laying any new surface over it without repair means the cracks reappear quickly, often within one season, and the full job needs redoing at greater cost.

Less than most surfaces. Occasional brushing or jet washing removes moss, algae, and surface dirt. Because the mix is dense and flush, weeds have little opportunity to establish compared with open-jointed or loose surfaces.

The most common causes are a weak or contaminated base, inadequate drainage, or ground movement that was not identified before laying. A thorough base condition survey before installation is the single most effective way to avoid these failures.

Generally no. Because resin bound is a permeable surface, it falls within permitted development rules for front gardens in England and does not require planning permission. If your property is listed or in a designated conservation area, you should check with your local planning authority before work begins.

Resin bound requires correct mixing ratios, temperature-controlled laying conditions, and a properly prepared sub-base. Errors in any of these cause surface failure. An experienced installer with a track record of resin bound work is essential; a general handyman without that specific background carries a high risk of a poor result.

The sub-base should be compacted, level, and free of standing water before any resin is mixed. You should be able to see the base layer before laying begins. A local contractor arranged through us will survey the site first and advise on preparation requirements before quoting, so nothing is hidden in the process.
