How to Lay a Gravel Driveway – DIY Guide
How to Lay a Gravel Driveway
Get a smart, low-maintenance driveway finish without the contractor costs.
Lay a gravel driveway by excavating 150mm of soil, compacting a MOT Type 1 sub-base, fitting edging, laying a weed-suppressing membrane, then spreading 50mm of angular gravel and raking level. The job takes a weekend and costs a fraction of tarmac or block paving.

Step-by-Step Guide
Mark Out and Excavate the Area
Use canes and string line to mark the driveway boundary, then excavate to a depth of 150–200mm to allow for sub-base, membrane and gravel layers. Remove all topsoil and organic material — if you leave soft ground underneath, the surface will sink and rut under vehicle weight. Dispose of spoil properly; many councils offer a bulky waste collection. If your driveway exceeds 5m² and drains onto the highway, check whether permitted development rules require a permeable surface — our Driveways & External Guide covers the planning rules in full.
Install Edging Restraints
Fix edging restraints around the full perimeter before any fill goes in — this stops gravel migrating onto the lawn, beds or road. Bed plastic or metal edging on a thin layer of compacted sharp sand, drive the fixing stakes into undisturbed ground at 500mm centres, and check the top edge is at your intended finished gravel level. Use a spirit level and rubber mallet to keep the edging straight and consistent. Poorly secured edging is the single biggest cause of gravel creep, so take time here.
Lay and Compact the Sub-Base
Tip MOT Type 1 crushed stone into the excavated area and spread it to a compacted depth of 100mm. Work in 50mm passes with a plate compactor — never try to compact the full depth in one go or you will get voids. Check for a firm, unyielding surface before moving on; any soft spots must be dug out and refilled. A solid sub-base is what gives a gravel driveway its load-bearing strength and prevents the gravel disappearing into the ground over time. If you are reusing an existing tarmac or concrete base in reasonable condition, you may be able to skip this step — see our guide to repairing a cracked driveway to assess its condition first.
Fit the Weed-Suppressing Membrane
Roll out a heavy-duty (minimum 100gsm) woven or non-woven membrane over the compacted sub-base, overlapping joins by at least 200mm. Peg the membrane down at 300–400mm intervals so it cannot shift when you tip gravel on top. Trim neatly against the edging with a Stanley knife. A quality membrane is essential — thin, cheap sheeting perforates within a season and weeds push straight through. Do not use standard polythene sheet; it holds water, causes the sub-base to shift, and degrades quickly.
Spread and Level the Gravel
Tip angular 10–20mm decorative gravel onto the membrane and rake it out evenly to a depth of 50mm. Angular gravel locks together far better than round pea shingle, reducing scatter and ruts under tyres. Work in sections, building from the back of the driveway towards the exit so you are not walking across finished areas. Avoid letting vehicles onto the gravel for at least 24 hours to allow the surface to settle. For areas prone to displacement, a plastic stabilisation mesh laid under the gravel significantly reduces gravel spreading on the driveway.
Check Drainage and Tidy Edges
Walk the finished surface and check that water runs away from the house — the driveway should have a natural fall of at least 1:60 towards a permeable border or a driveway drain, not towards the property. Rake any uneven patches and top up thin spots. Trim any membrane that is visible above the gravel line. If the drive adjoins the road, ensure no loose gravel is deposited onto the highway, as this is both a hazard and a highways liability. A tidy perimeter also dramatically improves the finished look — building a garden path alongside the drive using matching gravel ties the whole scheme together.
Frequently Asked Questions
Do I need planning permission to lay a gravel driveway?
In most cases, no — gravel driveways are permitted development in England because gravel is a permeable surface. However, if you are in a conservation area or the driveway fronts a classified road, you should check with your local planning authority first. Gov.uk guidance on hardstanding covers this in detail.
How deep should the gravel be on a driveway?
A minimum of 50mm of compacted gravel on top of the membrane is the working standard for a vehicle driveway. Too shallow and tyres displace the stone; too deep and it becomes difficult to walk on and harder to drive over.
What is the best gravel type for a driveway?
Angular crushed stone in a 10–20mm grade is the best choice — the irregular edges lock together under load and resist scatter. Avoid round pea shingle on driveways as it offers no interlock and migrates constantly under tyre pressure.
How do I stop weeds growing through my gravel driveway?
A heavy-duty woven membrane beneath the gravel is the most effective long-term solution. Top up the gravel layer annually to maintain the 50mm depth, as a thin layer lets light through and encourages weed germination at the membrane surface. You can also stop gravel spreading by using stabilisation mesh, which also helps suppress weeds.
How much gravel do I need for a driveway?
Calculate the area in square metres, multiply by 0.05 (for a 50mm depth), then multiply by the bulk density of your chosen gravel — typically 1.4–1.7 tonnes per cubic metre. A standard double driveway of around 40m² will need approximately 3–4 tonnes of decorative gravel.
Order your gravel in bulk 850kg dumpy bags rather than smaller bags — the per-tonne cost drops significantly and you avoid running short mid-job. Always order 10% extra to account for compaction, settlement and edge fill; returning excess is far easier than waiting for a second delivery when you are one barrow short of finishing.
