Concrete for Driveways in Birmingham
The right driveway mix is air-entrained — built to shrug off frost instead of flaking apart in it. We batch it fresh on your street, meter what's poured, and give you the straight story on kerbs and drainage while we're at it.
Driveway Concrete Is Air-Entrained — Here's Why
The mix for a domestic driveway is an air-entrained C25/30 at S2 consistence — what builders call PAV1. We batch an equivalent designed mix to the strength and durability requirements of BS 8500 / BS EN 206.
The part that matters is the air. Air entrainment is mandatory in PAV mixes — a minimum of 4.5% air at 20mm aggregate — and it isn't froth for its own sake. The entrained air is millions of microscopic bubbles that give freezing water room to expand inside the concrete. Without them, water in the surface freezes, expands, and pops the top layer off a flake at a time. That's the scaling you see on tired drives every spring.
Which is exactly what happens to plain C20 driveways: they scale and spall in frost. A driveway is outside, wet and frozen for a chunk of every Birmingham winter — it needs the paving mix, not the cheapest slab mix. The strength grade underneath it is C25/30; see our C30 concrete page for what that grade does elsewhere.
Air-entrained concrete must not be power-floated. Pass it on to whoever's finishing the slab before pour day, not after.
Heavier duty than a family drive — a salted commercial forecourt or a yard taking real traffic — steps up to a PAV2-equivalent air-entrained C32/40. If that's you, say so when you call.
How Thick, and How Much?
Guidance for driveways is a depth of around 150mm on a properly compacted sub-base. The maths is length × width × 0.15:
- A typical 5m × 3m drive: 5 × 3 × 0.15 = 2.25m³ — order around 2.5m³ with contingency.
- The council-minimum 4.75m × 3m hardstanding (more on that below): 4.75 × 3 × 0.15 = 2.14m³ — order 2.25–2.5m³.
Odd shapes, wider frontages, an extra parking bay? Run it through our concrete calculator — it handles the contingency and rounding for you. And because we batch on site and meter the pour, the contingency you don't use is contingency you don't pay for.
Dropped Kerbs in Birmingham: Do It Once, Do It Legally
Here's the bit most driveway pages skip. Birmingham City Council has received over 1,400 reports of illegal dropped kerbs — drives built first, kerbs dropped informally, questions asked later. It's not a grey area the council ignores.
The legal route, per council guidance: a proper dropped kerb typically runs around £1,500–£3,000, plus roughly £300 in application fees. And the order of operations matters — the council requires the driveway itself, at least 4.75m deep, to be in place before the kerb application, with permeable hardstanding or drainage to a soakaway within your property.
So the honest sequence is: sort the drainage design, pour the right driveway to the right depth, then apply for the kerb. Do it once, do it legally — a proper drive with a legal kerb is an asset; a drive you can't lawfully cross the footway to reach is an expensive slab. The application itself is between you and the council — check their current requirements, because we supply concrete, not legal advice. What we'll guarantee is our half: the right air-entrained mix, batched on your street, on the day your contractor wants it.
Permeable Options — an Honest Note
Porous concrete exists, and it's one way to meet the permeable-hardstanding requirement; the other is a conventional slab draining to a soakaway within your property. Which suits your drive depends on falls, ground and layout — and that's drainage design, which is your contractor's domain, not something a concrete supplier should sketch over the phone.
What we bring: once your contractor has decided the approach, we batch what the design calls for and you pay for the metered volume. Ask us about porous mixes when you call and we'll tell you straight what we can and can't do.
Driveway Concrete Prices
| Mix | Use | Guide price per m³ |
|---|---|---|
| Air-entrained C25/30 (PAV1-equivalent), S2 | Driveways, domestic parking, external paving without de-icing salts | from £115 (C30 strength — air-entrained spec confirmed when you book) |
| Air-entrained C32/40 (PAV2-equivalent), S3 | Heavy-duty or salted paving | from £128 (C40 strength) |
All prices per m³, +VAT (add 20%), guide prices — confirmed when you book. The 2.25m³ drive above is therefore roughly £260–£290 +VAT of concrete, metered as it pours. The full picture — every grade, small loads, pumping, weekend surcharges — is in our ready mix concrete prices guide. Pouring a garage floor at the same time? See concrete for shed and garage bases — we can batch both mixes from one visit.
Driveway Concrete FAQs
What is the best concrete mix for a driveway?
An air-entrained C25/30 — the mix builders call PAV1. Air entrainment is mandatory in PAV mixes: a minimum of 4.5% air at 20mm aggregate, as microscopic bubbles that give freezing water room to expand. That's what stops the surface scaling off in frost. We batch an equivalent designed mix at S2 consistence.
How thick should a concrete driveway be?
Around 150mm is the guidance for driveways and garage floors, on a properly compacted sub-base. At 150mm, a typical 5m × 3m drive needs 2.25m³ — order around 2.5m³ with contingency, or check your own dimensions with our concrete calculator.
When can I park on a new concrete driveway?
Light foot traffic after 24–48 hours; cars after about a week to be safe; heavy vehicles should stay off for 28 days, when concrete reaches its design strength. Keep it covered and damp for the first few days — curing is what develops the surface durability a driveway lives or dies by.
Do I need a dropped kerb for my driveway in Birmingham?
If you'll be driving over the footway to reach it, yes — and with over 1,400 illegal dropped kerbs reported to Birmingham City Council, it's enforced. A legal one typically runs around £1,500–£3,000 plus roughly £300 in application fees, and the council requires the driveway — at least 4.75m deep — in place before the application. Check the council's current requirements; we supply the concrete, not legal advice.
Does my driveway need to be permeable?
Birmingham's dropped-kerb rules require permeable hardstanding — porous concrete — or drainage to a soakaway within your property. Porous concrete exists and we're happy to talk it through, but drainage design is your contractor's domain, not something a concrete supplier should be designing over the phone.
Why not just use a cheaper C20 mix for a driveway?
Frost. Plain C20 driveways scale and spall in freeze-thaw weather: water gets into the surface, freezes, expands, and flakes the top off a little more each winter. The air-entrained mix costs a little more per cubic metre and lasts the difference many times over.
