How deep should a gravel driveway be?

The decorative stone itself should sit 40–50mm deep — any deeper and tyres plough through it. What matters more is what is underneath: a compacted MOT Type 1 sub-base of 100–200mm depending on ground conditions and vehicle weight.

Will the gravel stay in place?

With angular stone, a properly haunched edge and a level base, yes. On sloping drives or where cars turn on the spot we fit a cellular gravel grid, which holds the stone in individual cells and effectively stops migration.

Do I need planning permission for a gravel driveway?

Gravel is a permeable surface, so front driveways in England generally do not require planning permission provided water drains within your own boundary rather than onto the highway. We design the falls with that in mind.

How much does a gravel driveway cost in Farnham?

Gravel is typically the most affordable full driveway installation, though the final figure depends on excavation depth, disposal, edging and whether a retention grid is used. We survey the site and give you a written quote with the build-up specified.

Can you lay gravel over my existing driveway?

Sometimes. If an old tarmac or concrete base is sound and drains, it can make an excellent foundation for gravel with an edge added. If it is cracked, sunken or holding water, laying over the top only hides the problem.

How do I stop weeds in a gravel drive?

A quality membrane directly under the stone stops weeds growing up from below. Most weeds in an established gravel drive actually germinate in leaf litter on top, so an autumn clear-out does more good than anything else.

Gravel is one of the most misunderstood driveway surfaces we install around Farnham. Laid straight onto soil it turns to mud within two winters; laid on a compacted sub-base with proper edging and retention it is one of the longest-lived, lowest-cost surfaces you can buy.

Is gravel right for your property?

Gravel works best on longer approach drives, level or gently sloping frontages, and properties where a soft, traditional look matters more than a perfectly smooth surface. It is the natural fit for the rural plots around Frensham, Tilford and Elstead, and for period houses where resin or tarmac would look wrong against the brickwork.

It is less suited to steep gradients, where stone migrates downhill, and to homes where wheelchair access, pushchairs or bicycle use matter. On steeper sites we usually recommend either a bound gravel system or a block-paved wheel track through the gravel.

The build-up underneath

Every gravel driveway we install around Farnham is excavated to between 150mm and 250mm depending on ground conditions and whether vehicles will be heavier than a family car. Soft spots are dug out rather than bridged over.

A geotextile separation membrane goes down on the formation to stop the sub-base punching into the subsoil. MOT Type 1 is then laid and whacker-compacted in layers, and a second weed membrane sits above it, directly beneath the decorative stone. That second layer is what keeps weeds down and stops the gravel disappearing into the base.

Where a drive gets daily turning traffic we fit a cellular gravel grid on top of the sub-base and fill the cells with stone. It costs more up front, but it stops rutting and keeps the surface level for a decade or more.

Choosing the gravel

Angular 10–20mm stone knits together and stays put. Rounded pea shingle looks pretty in a photograph and then rolls under your tyres — we rarely recommend it for a driveway. Colour is worth choosing on site against your brickwork rather than from a brochure.

Cotswold buff — warm and traditional, flatters greensand stone and red brick
Silver or Scottish granite — cool grey, sharp against modern render
Flint and Breedon-style self-binding gravel — compacts to a firmer surface
Golden quartz — bright, holds its colour when wet

Edging, retention and drainage

Gravel needs something to push against. We fit either a concrete-haunched block or kerb edge, timber or steel edging on informal drives, or a brick soldier course where the drive meets the house. Without it, the stone ends up on your lawn and in the road.

Because gravel drains through its own surface, most drives need no additional drainage. Where a drive falls towards the house or garage we still install a channel drain across the threshold, and where the sub-base sits on Farnham's heavier clay we build in a soakaway so water has somewhere to go in February.

Maintenance and the honest downsides

Gravel needs raking level once or twice a year, and a top-up of stone every five to eight years where it thins at the turning points. Leaves need clearing in autumn or organic matter builds up and gives weeds somewhere to root.

The genuine drawbacks: stone travels into the house on shoes, snow clearance is awkward, and it is not the surface for you if you want something you never think about. If those matter, resin bound gives you a similar permeability with none of the movement.

How we build it

The installation process, step by step.

01
Survey and levels
We check gradients, existing drainage and where water currently goes before quoting anything.
02
Excavation
Dig out to 150–250mm, remove soft spots and cart away all arisings.
03
Membrane and sub-base
Separation membrane, then MOT Type 1 compacted in layers to a firm, even formation.
04
Edging
Concrete-haunched kerb, block or steel edge set to line so the gravel is contained.
05
Grid or weed membrane
Cellular grid where traffic demands it, otherwise a heavy weed membrane over the base.
06
Gravel and clean-down
Stone spread to an even 40–50mm depth, raked true and the site left swept and clear.
