Get the access wrong and your pour gets cancelled, or worse — a truck gets stuck. Here's exactly what you need to prepare before the mixer arrives.
A standard ready-mix concrete truck is 2.5 m wide, up to 12 m long, and weighs up to 32 tonnes fully loaded — your access route must accommodate all three dimensions with a firm, load-bearing surface rated to at least 32 tonnes. Most pours are cancelled or delayed because the site hasn't been measured or cleared in advance.
Ready-mix concrete has a working life of roughly 90 minutes from batching. Once the truck leaves the plant, the clock is running. If access delays the delivery — an overhanging branch, a soft verge, a gate that's 10 cm too narrow — you risk losing the load entirely, and you'll still be billed for it. Preparation costs nothing; a wasted load costs £400–£1,200.
| Measurement | Typical Figure | Notes |
|---|---|---|
| Vehicle width | 2.5 m | Add 0.5 m each side for safe clearance = 3.5 m minimum gate/drive width |
| Vehicle length | 9–12 m | Articulated trucks need up to 14 m turning radius |
| Height (drum included) | 3.8–4.0 m | Check all overhead obstacles: trees, cables, canopies |
| Gross laden weight | 26–32 tonnes | Confirm ground-bearing capacity of drives and verges |
| Chute reach (standard) | 3–4.5 m | Extended chutes or pump hire needed beyond this |
| Pump truck width | 2.6–3.0 m | Pump lorry requires separate clear access and outrigger space |
Walk the full route from the highway to the pour point with a tape measure. Record the narrowest width (gates, posts, walls), the lowest overhead obstruction (trees, eaves, power lines), and the tightest turn radius. Compare every figure against the truck dimensions above.
A fully laden mixer exerts roughly 8–10 tonnes per axle. Block-paved driveways, clay subsoils, and recently filled ground can fail under this load. Lay temporary road plates (steel, typically 2.4 m × 1.2 m × 16 mm) over soft or vulnerable surfaces. Steel road plates are hireable for £15–£40 per plate per day.
Remove parked vehicles, bins, skips, scaffolding boards, and any loose materials from the access path. Trim or tie back overhanging branches to achieve 4.2 m of headroom — 200 mm above the truck's maximum drum height as a safe margin.
A minimum clear gate opening of 3.5 m is recommended for a standard mixer with safe working clearance. If your gate opening is 3.0 m or less, discuss a mini-mix truck (typically 1.8–2.0 m wide, carrying 1–3 m³) or a concrete pump with your supplier.
Mark exactly where the truck will park and where the chute will discharge. The chute reaches 3–4.5 m; anything beyond that needs a pump, a conveyor, or a skip-and-barrow relay. Confirm with your supplier which method suits your pour volume and access.
Designate one person (not the mixer operator) to guide the vehicle onto the site, communicate clearances, and watch for hazards. This is especially critical in tight residential drives or shared access routes.
For shared drives or narrow roads, inform adjacent households 48 hours in advance. Lay heavy-duty polythene sheeting (1,000–1,200 gauge) or timber boards over block paving, pattern-imprinted concrete, or soft landscaping adjacent to the chute zone.
Before booking, email or confirm in writing: gate width, lowest overhead obstacle, surface type, and whether a pump is required. Suppliers may adjust the mix design, truck size, or schedule based on your answers. This record protects you if there's a dispute on the day.

There is no single British Standard prescribing driveway load capacity for delivery vehicles, but BS 8500-1:2023 (the UK standard for specifying concrete) is relevant to the mix design for any base or hardstanding you're protecting or constructing. For temporary access over soft ground, the general engineering principle is that a minimum subbase of 150 mm compacted Type 1 MOT granular fill is required to spread axle loads before steel road plates are laid — this is consistent with guidance in BS 6031 (earthworks).
The number-one reason a residential pour is cancelled on the day isn't weather or mix problems — it's a gate, a branch, or a soft verge that nobody measured.
A standard ready-mix truck is 2.5 m wide; you need a minimum clear gate opening of 3.5 m to allow safe passage with working clearance on each side. If your gate is narrower than this, a mini-mix truck (1.8–2.0 m wide) or a concrete pump fed from the road may be the only viable options.
A fully loaded standard ready-mix truck weighs between 26 and 32 tonnes, with individual axle loads of roughly 8–10 tonnes each. Standard block-paved or tarmac residential driveways are typically not designed for this load, so steel road plates (hireable at £15–£40 per plate per day) should be laid over vulnerable surfaces.
A standard ready-mix chute reaches 3–4.5 m from the rear of the truck. If your pour point is further away, you'll need a pump truck (hose reach up to 150 m, hire cost £350–£600), a conveyor extension (6–12 m reach, £100–£250 hire), or a barrow-relay using dumpers or wheelbarrows.
Most residential driveways are not built to carry 26–32 tonne loads. A concrete truck should generally not be driven directly onto block paving, pattern-imprinted concrete, or soft/recently laid ground without steel road plates or temporary matting underneath. Always assess the subbase depth and surface condition before allowing a truck to access — and confirm with your supplier.
Ready-mix suppliers typically allow a free waiting window of 5–10 minutes; after that, most charge £2–£5 per minute. Concrete also has a working life of around 90 minutes from batching, so a delay of 20–30 minutes can seriously compromise the pour quality — and you'll still pay for the load.
A line pump (also called a trailer pump) typically costs £350–£600 to hire for a day in the UK, plus the standard cost of the concrete itself. A boom pump (for larger volumes or greater height) costs more, from £600–£1,200+. Pump hire is usually worthwhile when the pour point is more than 4.5 m from where the truck can park, or where the route is too narrow for the truck.
A mini-mix truck is a smaller ready-mix vehicle — typically 1.8–2.0 m wide and carrying 1–3 m³ of concrete — designed for restricted residential access. You'll need one when your gate or access route is under 3.5 m wide. Mini-mix concrete typically costs 15–30% more per cubic metre than standard truck delivery due to the smaller load size.
