Resin driveway vs block paving
Most comparisons of these two surfaces are written by someone who installs one of them. That is worth knowing before you read. MacColl & Stokes has been fitting both resin bound and block paved driveways for over 40 years, and we have no preference between them. The right surface depends on the property, and this post gives you an honest read on both.
The short version: resin bound is the better choice for a modern, weed-free, low-maintenance finish. Block paving is the better choice where repairability and pattern flexibility matter. On cost, the two are closer than most installers will tell you. Which one lasts longer depends almost entirely on how well the base is built, not which surface sits on top.
The short answer
Neither surface wins outright. The right call depends on your property, how much maintenance you are prepared to do, and what matters most to you long term.
Here is how they compare:
Cost per m² installed: resin bound, £70 to £130; block paving, £60 to £120. The ranges overlap considerably, and the base specification drives price variation far more than the surface material.
Lifespan: resin bound, 15 to 25 years when the base is correct; block paving, 20 to 30 years with the option to relay individual sections indefinitely.
Maintenance: resin bound needs almost none after installation. Block paving needs periodic resanding and annual weed control.
Repairability: block paving wins. Individual blocks can be lifted and relaid without visible evidence. Resin repairs are always visible.
Drainage: resin bound is permeable by design. Standard block paving is not, though permeable block specifications exist.
Best suited to: resin for modern properties, large unbroken areas, and low-maintenance priorities; block paving for period properties, irregular shapes, and anyone expecting groundwork under the drive in the next decade.
The sections below explain the reasoning behind each point.
What resin bound actually is
Resin bound surfacing is a mix of aggregate and resin combined on site, then trowelled over a prepared sub-base as a single continuous layer. The critical distinction is that the aggregate is fully coated within the resin, not scattered on top of it. This makes the surface permeable: water passes down through the voids between particles rather than running off to the edges.
This is not the same thing as resin bonded, which is a different product and a different result. Resin bonded surfaces have stones pressed into a resin coat already spread on the base. They can shed stones over time, and they are not permeable. A noticeably cheap quote for a resin driveway is often for a resin bonded product. If you are comparing quotes, ask directly which type is being priced.
Since the finish of any resin surface depends almost entirely on what is built beneath it, it is worth understanding why resin driveways look so different from one property to the next before you start comparing quotes or specifications.
What block paving actually is
Block paving uses individual precast concrete or natural stone units, bedded onto a layer of sharp sand over a compacted sub-base. Once the blocks are laid, kiln-dried sand is brushed into the joints, and edge restraints on all sides hold the surface stable under vehicle loading.
Pattern choice affects durability as much as appearance. Herringbone is the standard for vehicle areas because the interlocking geometry resists creep and rocking under repeated loading. Straight-bond or stack-bond patterns are more prone to movement over time. Most professional installers specify herringbone on driveways as a matter of course.
Material quality varies considerably. Standard concrete blocks are serviceable, but cheaper units use a thin surface colour layer that wears away over five to ten years. Matching them later for repairs becomes difficult once shades are discontinued. Natural granite setts cost more but are exceptionally long-lived and almost impossible to wear out.

Cost, and where the cheap quotes go wrong
Installed costs for resin bound in Central Scotland run from £70 to £130 per square metre, depending on aggregate choice, base conditions, drainage requirements, and access. Block paving sits between £60 and £120 per square metre for a professionally installed job.
Both surfaces are broadly comparable on price. What varies far more dramatically is the quality of the sub-base, and this is where low quotes create expensive problems.
A standard driveway sub-base requires a minimum of 150mm of compacted MOT Type 1 granular fill, laid and consolidated in 75mm layers. On soft ground or clay-heavy sites, 200mm is more appropriate. The difference in material and labour between those two specifications can be £10 to £15 per square metre. When two quotes for nominally the same job diverge by that margin, the base depth is almost always the explanation. A thinner base is quicker and cheaper to build. It is also the leading cause of driveway failure within three to five years of installation.
Ask every contractor the same question: what depth is your sub-base, and is it compacted in layers with a mechanical plate? A competent installer answers that without hesitation.

Which one lasts
A driveway built to the correct specification will serve for two decades or more, whichever surface you choose. The failure modes are different, and understanding them is more useful than a headline lifespan figure.
What are the pitfalls of resin driveways?
The most common cause of resin failure is the sub-base, not the resin itself. Resin bound is a thin surface layer, typically 15 to 18mm. Any movement in the ground beneath transfers directly to the surface. A correctly built MOT base, compacted in layers and given time to cure before the surface is applied, gives resin a working life of 20 to 25 years. That is the honest answer on life expectancy: 20 years minimum when installed properly, considerably less when the base is underspecified.
UV-sensitive polyurethane resin yellows and becomes brittle within a few years in direct sunlight. Reputable installers specify aliphatic resin, which is UV-stable. It costs more, and cheaper quotes often substitute the inferior product without telling you.
Edge finishing is the third failure point. Where resin meets a channel, kerb, or adjacent surface, the bond has to be clean and fully adhered. Edges that lift by year two or three are almost never a product failure. They are an installation one.
What ends a block paved driveway?
Block paving fails gradually rather than suddenly. The first sign is usually sand loss from the joints: once kiln-dried sand washes out, blocks begin to rock slightly under vehicle loading and unevenness follows. Periodic resanding, typically every three to five years on a well-used drive, resets this and extends the surface life considerably.
Settlement near drainage points and manholes tends to come next, since these areas often have a weaker sub-base. Weed growth in the joints is an aesthetic problem more than a structural one, but it signals that the jointing sand has broken down and the joints need refreshing.
The practical advantage of block paving is that any section can be lifted and relaid. Drainage works, service repairs, or localised settlement can all be addressed without leaving a visible mark.
Maintenance, honestly
This is where resin bound and block paving diverge most clearly, and the gap is significant.
A resin bound surface installed to specification needs almost no maintenance. Leaves and debris wash off in rain or blow clear. Moss can develop on shaded north-facing areas but sits on the surface rather than in it, and a light jet wash removes it. There is no resanding, no weed treatment, and no periodic sealing required.
Do weeds come through resin driveways?
No. A properly installed resin bound surface does not allow weed growth through it. The only scenario where vegetation appears is when debris accumulates in a low point and seeds germinate on top of the surface rather than through it. This is a surface maintenance issue, not a structural one, and it clears easily.
Block paving is a different story. Weed growth in the joints is normal from year two or three onwards, regardless of how well the driveway was installed. This is not a workmanship problem; it is how kiln-dried sand behaves over time when exposed to weather and organic matter. Annual weed treatment and top-up resanding are routine parts of owning a block paved driveway.
Can I jet wash a resin driveway?
Yes, at the right pressure. A domestic pressure washer running at 1,200 to 1,500 PSI with a wide fan nozzle is appropriate. Keep the lance moving and hold it at least 30 centimetres from the surface. Very high pressure, a pencil jet, or a nozzle held stationary close to the surface will strip aggregate from the resin over time. The aim is to shift surface-level moss and debris, not to blast into the material.
Scottish weather
Freeze-thaw cycles are the main stress test for any driveway surface. Water expands by around 9% when it freezes. If water has worked into the sub-base through a compromised surface or degraded joints, that expansion moves the base material. The thaw does not return it to exactly the same position. Over several winters, this produces cracking, block rocking, and surface lift.
Both surfaces handle Scottish conditions well when built correctly. Resin bound has a natural advantage: its permeability means water drains through rather than pooling on the surface and working into joints. Standard block paving allows water to collect at joint level, and once the jointing sand has degraded, that water reaches the base.
North-facing driveways under tree canopy are the hardest case. Surface drying time is longer, moss establishes faster, and freeze-thaw cycling is more frequent on surfaces that stay damp. MacColl & Stokes completed a resin bound installation on a particularly shaded north-facing property as part of the Bearsden garden project, and the specification approach taken there was designed specifically around these conditions.
Drainage and planning
Any new driveway that is not permeable requires planning permission in Scotland and England. The regulation has been in place since 2008 and exists to limit surface water runoff into local drainage systems. It catches a lot of homeowners by surprise.
Resin bound is permeable by design and satisfies this requirement without any additional measures. Standard block paving is not permeable, though permeable block specifications are available where open joints and a permeable sub-base are designed in from the start. Alternatively, a drainage channel directing surface water to a planted border or soakaway can satisfy the requirement for a conventional block paved surface.
Both approaches are available through MacColl & Stokes, and the driveways service page covers what the team installs across Central Scotland.
So which should you choose?
A direct answer rather than a list of considerations.
Choose resin bound if you want a low-maintenance, contemporary finish on a large, unbroken driveway area. It suits modern properties where the continuous, flat surface works with the architecture, and it is the right choice for anyone who does not want to think about driveway upkeep from year to year. For large areas in particular, the absence of joints means no progressive sand loss, no weed pressure, and no section-by-section movement to manage.
Choose block paving if your property is period or traditional in character, if the shape involves tight curves, planted borders, or irregular edges, or if there is any likelihood of drainage or services work under the driveway in the coming years. The ability to lift and relay without a visible patch is a genuine practical advantage. Block paving also suits driveways where a pattern or texture is important to the overall design of the front of the property.
On cost, the two surfaces are close enough that it is rarely the deciding factor.
Whatever surface you choose, the most valuable conversation you can have with an installer is about the base. Ask what depth of sub-base is being specified, whether the ground has been assessed, and how the base will be compacted. A contractor who cannot answer that precisely is the real risk, not the surface material.
MacColl & Stokes installs both surfaces across Central Scotland and offers a site visit before any specification is committed to. Most decisions become clear once someone has looked at the ground conditions, the gradient, and the front of the house. If you want to start that conversation, get in touch to arrange a visit.
