The digout is the biggest cost
Gravel is a thin dressing on top of a deep build. A drive carrying cars needs the ground taken out to a depth that suits the weight, then a compacted stone sub-base built back up in layers. That excavation, the stone to refill it and the removal of the spoil are usually the largest part of the quote, and they are invisible once the drive is finished.
This is why a quote that seems cheap deserves a second look. A drive laid with a shallow digout and a thin base looks identical on day one and starts rutting within a year.
Size, shape and what is there now
The area is the obvious factor, but the starting point matters as much. Replacing an old gravel drive where the base is sound costs far less than converting a lawn, which needs full excavation. Breaking out an old concrete strip adds labour and waste. A long, narrow drive costs more per square metre than a square one because there is more edging per unit of area.
- Converting a lawn: full digout and spoil removal
- Replacing old gravel: often a top up if the base is sound
- Breaking out concrete or tarmac: extra labour and waste
- Awkward shapes: more edging and more cutting of the membrane
The stone itself
Gravel for a drive needs to be a hard, angular stone that locks together under tyres, at a sensible size: too fine and it travels, too large and it is uncomfortable underfoot. Decorative stones cost more per tonne than standard gravels, and the depth of the top layer affects the total tonnage. Ashley talks through the options on the visit, and the gravel and decorative stone page shows how loose stone is laid and edged.

- Full groundwork preparation
- Drainage considered from the start
- Clear, tidy finishing
Edging, membrane and drainage
Three smaller items decide how the drive lives. Edging keeps the stone on the drive and off the pavement and lawn, and a drive without firm edging spreads within months. A membrane under the stone stops it mixing into the soil below and slows weeds coming up. Drainage is usually simple with gravel because rain soaks through, but the ground still has to accept the water, and flat or heavy sites may need a channel or soakaway planned in.
Access and the working day
Loose stone arrives by the tonne and has to move from the delivery point to the drive. A frontage where a lorry can tip beside the work is quicker than one where every barrowload travels a distance. Parking for delivery vehicles, keeping the pavement clear and timing waste collection all shape the working day, and on terraced streets they are agreed before the job starts.
Gravel against the alternatives
Gravel is generally the quickest and most affordable surface to lay, and it drains naturally. Slabs cost more and take longer but give a firm, swept finish that suits short frontages and heavy daily use. Our comparison guide goes through the trade offs in detail, and the driveways page covers how both are built.
Getting a figure for your drive
Because the digout, the base and the access decide so much of the cost, a sensible figure only comes from looking at the site. Ashley visits, checks the ground and access, talks through the stone and edging choices, and prices the whole job including waste removal, so there are no surprises later.
