In short
- Resin-bound stone is mixed with resin and trowelled, giving a smooth, porous finish. Resin-bonded stone is scattered onto a resin layer, giving a textured finish that is generally not permeable.
- A resin surface is only as good as the base under it. Most early failures trace back to a weak base, damp or cold laying conditions, too little resin or poor edges.
- UV-stable aliphatic resins are designed to resist yellowing. Aromatic resins can darken in sunlight, which shows most on pale stone.
- Resin-bound is commonly quoted as lasting 15 to 25 years when installed correctly, but that depends on the base, the traffic and how it is looked after.
- Block paving, tarmac and gravel all have strengths, particularly for heavy vehicles, steep slopes, easy repairs and rural or heritage settings.
Resin-bound and resin-bonded: two different surfaces
The two names sound almost the same, and some adverts use them loosely, but they describe different ways of building a surface. It is worth knowing which one a quote describes before you compare prices, because they look, drain and wear differently.
| Resin-bound | Resin-bonded | |
|---|---|---|
| How it is made | Dried stone is mixed with resin in a forced-action mixer, then spread and hand-trowelled to a set depth over a prepared base. | A thin coat of resin is spread over a solid base and loose stone is scattered onto it while it is wet. The excess is swept off once it has cured. |
| Finish | Smooth and even, with every stone fully coated. No loose stones once cured. | Rough and textured, like a fixed gravel. Each stone is only partly held in the resin. |
| Water | Porous. Water passes through gaps between the stones, so it can be permeable if the base below is permeable too. | The resin forms a continuous skin, so water generally runs off rather than soaking through. |
| Typical uses | Driveways, patios, paths, tree pits and communal areas where a smooth, step-free surface is wanted. | Slopes, ramps, steps and paths where grip matters, and rural drives where a gravel look fits in. |
| Wear | Wears slowly if the mix and base are right. Worn or damaged areas are cut out and relaid. | Some stone comes loose at first. Bald patches can usually be recoated with fresh resin and stone. |
In practice, most enquiries for a new resin driveway in Kent are for resin-bound, because it is porous and can help a front garden drive stay within the permitted development rules for permeable surfacing. Resin-bonded still has a place, especially where grip on a slope matters more than drainage, and it can be a sensible way to give a sound tarmac drive a fresh, gravel-like look.
Five driveway surfaces side by side
The table below compares the five surfaces most Kent homeowners consider. Cost bands are relative only, because the groundwork, the size and shape of the drive, access and drainage often move the price more than the choice of surface. The cost guide on this site sets out published price ranges.
| Resin-bound | Resin-bonded | Block paving | Tarmac | Gravel | |
|---|---|---|---|---|---|
| Look | Smooth, seamless stone finish in many blends | Textured, gravel-like finish | Individual blocks in many colours and patterns | Plain black or coloured asphalt | Loose stone, traditional and informal |
| Permeability and SuDS | Porous, and permeable when laid on a permeable base | Generally impermeable, so run-off must go to a permeable area or drain | Standard blocks shed most water; permeable block systems exist | Standard tarmac is impermeable; porous asphalt exists | Free-draining on an open sub-base |
| Base needed | A sound bound base: new open-graded sub-base and porous binder course, or sound existing tarmac or concrete | A sound bound base such as tarmac or concrete | Compacted sub-base and a sand or grit laying course | Compacted sub-base and a base or binder course | Compacted sub-base, often with a membrane or stabilising grid |
| Weed resistance | Good, as there are no joints, though seeds can root in dirt on top | Good while the resin layer is intact | Weeds and moss can grow in the joints | Good while sound, but weeds find cracks and edges | Weeds grow through without a membrane and upkeep |
| Maintenance | Regular sweeping and occasional careful washing | Sweeping up loose stone, and recoating when worn | Weeding, cleaning and re-sanding joints | Sweeping, and patching or sealing as it ages | Raking, topping up and weeding |
| Repairability | Patches are possible but colour matching is hard | Worn areas can be recoated | Individual blocks can be lifted and relaid | Patches are common but usually visible | Easy to rake level and top up |
| UV stability | Depends on the resin; aliphatic types resist yellowing | Less of an issue, as stone hides most of the resin | Colours can fade over time | Black tarmac fades to grey | Not an issue |
| Typical lifespan | Often quoted as 15 to 25 years when installed correctly | Varies; the surface may need recoating sooner | Long-lasting on a sound base, though no single figure is published | Long-lasting, with major repairs often needed after 15 to 20 years | Indefinite, with regular topping up |
| Heavy vehicles | Cars and vans on a properly designed base; not designed for regular heavy traffic | Depends on the base underneath | Good on a deep enough base | Good, and widely used for heavier traffic | Can rut under heavy or turning wheels |
| Slopes | Moderate slopes; steeper ones need care and an anti-slip finish | Good grip on slopes | Good with firm edging | Good | Stone migrates downhill |
| Relative cost | Mid to higher | Lower to mid | Mid to higher | Lower to mid | Lower |
The resin-bound lifespan figure comes from manufacturers' expectations reported by MyJobQuote and in an article in Build It, and the tarmac figure from a Rated People cost guide. Treat all lifespans as hedged: a drive on a weak base can fail in a few years whatever the surface, while a well-built one in a quiet cul-de-sac may last much longer.
Aliphatic or aromatic resin, and why some drives turn yellow
Most resin-bound driveway systems use a polyurethane resin, and polyurethanes come in two broad chemical families. Which one your installer uses decides how the surface looks after a few summers.
- Aliphatic resins are described as UV-stable. They are designed to stay clear in sunlight, so the stone underneath keeps its colour. They cost more per kilogram than standard resin.
- Aromatic resins are not UV-stable. Sunlight can make them darken and turn yellow or amber over time, and manufacturers say exposure can affect other properties such as flexibility too.
- The effect is most obvious on pale stone blends, such as silver, white or light buff mixes, and on south-facing drives with little shade.
- On a resin-bonded surface the resin sits under the stone, so sunlight reaches very little of it. Some suppliers say aromatic resin can be acceptable there, but check with your installer.
A small amount of colour change in any outdoor surface is normal as stone weathers. The concern with aromatic resin on resin-bound is a distinct yellowing film across the whole surface, which can't be cleaned off. Because the resin is mixed through the whole layer, the only real fix is to resurface.
Why resin driveways fail: base, weather, resin content and edges
Resin-bound is a thin wearing layer, so it can't hide problems underneath it. Most failures that homeowners see in the first few years come down to one of four causes.
- A thin or weak baseIf the sub-base is too shallow, poorly compacted or laid on soft ground, the drive moves under car wheels. The resin follows that movement, so cracks, dips and ruts appear. Laying over old tarmac or concrete that is already cracked or sinking has the same effect.
- Laying in wet or cold weatherPolyurethane resins react with moisture. Damp stone, a wet base, rain during laying or heavy dew can leave a cloudy or milky surface and a weaker bond. Cold slows curing and makes the mix stiff and hard to trowel.
- Too little resinEach system has a set resin content for its stone. Skimping on resin, or using damp stone that stops it coating properly, leaves a surface that sheds stones and crumbles, often first where cars turn.
- A poor edge restraintResin-bound needs a firm edge to trowel against and to stop the edges breaking away. Without kerbs, metal or timber edging, or a solid wall line, the edges of the drive can crumble under tyres.
Other causes include too thin a resin layer for vehicles, badly blended joints between batches, and laying over a dirty base or fresh tarmac that hasn't cured. None of these is obvious on the day the drive is finished, which is why the questions you ask before you sign matter.
Slopes, heavy vehicles and turning circles
Most domestic resin-bound systems are designed for cars, vans and occasional delivery vehicles, laid on a base built for those loads. An article in Build It quotes a manufacturer saying that standard installations aren't designed for regular traffic over 10 tonnes, such as agricultural equipment or lorries, and that sites with heavy turning traffic need a suitability survey. If you have a motorhome, horsebox, tractor or frequent heavy deliveries, tell installers at the start.
- Turning wheels wear a surface far more than straight driving, so tight turning areas at the top of a drive or in front of garages need a strong base and a well-mixed surface.
- On slopes, resin-bound can be laid on moderate gradients, but the mix can slump on steep ones and grip can be an issue in frost. Installers may suggest an anti-slip additive, resin-bonded, or a different surface for very steep sections.
- Gravel is a poor choice on slopes because the stone migrates downhill, and block paving or tarmac can be more forgiving where vehicles are heavy.
- If the drive will cross a public footway, the highway authority also needs to know about vehicles over 3.5 tonnes when you apply for a dropped kerb.
Matching the surface to Kent house types
Kent's housing is varied, and different surfaces suit different streets. These are common patterns, not rules. An installer who visits will be able to say what works on your plot.
| Setting | Surfaces that often suit | Things to watch |
|---|---|---|
| Victorian and Edwardian terraced front gardens, for example in Chatham, Gillingham, Gravesend, Margate or Ramsgate | Resin-bound for a small, tidy permeable forecourt or path; sometimes a resin path with planting rather than parking | Many front gardens are too shallow to park in without overhanging the pavement, which affects dropped kerb approval. Conservation areas, original tiled paths and boundary walls may need to be kept. |
| 1930s and post-war semis and detached houses | Resin-bound or permeable block paving for a full-width drive | Old concrete or tarmac drives may look sound but hide cracks, so ask whether they can be overlaid or need digging out. |
| New-build estates, for example around Kingsnorth, Ebbsfleet, Hawkinge or the edges of Maidstone and Medway | Resin-bound over an existing sound base, or matching the estate's block paving | Check the title deeds and planning conditions for restrictions on front gardens, and whether the road and footway have been adopted by the highway authority yet. |
| Rural drives in the Weald, the Kent Downs and the marsh villages | Gravel, resin-bonded or tar and chip for long runs; resin-bound near the house | Long drives make every square metre count, and soft verges, farm vehicles and run-off onto lanes need thought. A loose or bonded gravel look may fit the setting better. |
| Coastal homes in Thanet, Folkestone and Hythe, and Dover and Deal | Resin-bound or block paving | Wind-blown sand and salt spray add to cleaning, and exposed sites leave little weather window for laying. |
In listed buildings and some conservation areas, a smooth resin finish may look out of place in front of historic houses, and the council may prefer gravel or traditional materials. Speak to the council's conservation officer before committing, particularly in places such as Rochester, Faversham, Sandwich, Tenterden or Tunbridge Wells.
Choosing a surface: questions to settle first
Before you ask for quotes, it helps to settle a few questions. Your answers narrow the options and make quotes easier to compare.
- Is the area a front garden that drains to the road? If so, a permeable surface, or one that drains to a lawn or border, usually avoids the need for planning permission.
- What is there now, and is it sound? A cracked or sinking surface usually means digging out, which changes the comparison between surfaces.
- Which vehicles will use it, and do they turn on it? Heavy or frequent turning traffic favours a stronger build.
- Is it sloped? Steep drives may need an anti-slip finish, resin-bonded, or a different surface for part of the run.
- How much maintenance are you happy to do? Gravel needs raking and topping up, block paving needs weeding, and resin needs regular sweeping.
- Do you need a new dropped kerb? If so, check the highway authority's criteria before you design the drive.
