Laying a Gravel Path That Lasts for Years

Why Most Gravel Paths Fail Within a Season

Gravel is one of the most forgiving surfaces you can lay in a British garden. It suits cottage planting, takes the muck off muddy boots, and costs a fraction of stone paving. Yet most gravel paths that look scruffy after two winters failed for one of three reasons: the ground beneath was soft, the gravel was laid straight onto soil, or the edges were never contained. Get these three things right and a gravel path will quietly serve you for fifteen years or more with nothing more than an occasional rake.

The good news is that none of the work is difficult. It is mostly a matter of digging deeper than you think necessary and being patient with a compaction plate.

Building a Sub-Base That Won't Move

Gravel is only the visible layer. It is the sub-base underneath that carries your weight, the wheelbarrow's weight, and the slow heave of winter frost. Aim for a minimum of 100mm of compacted sub-base for a garden path, and 150mm if you will ever run a car over it.

Start by marking the path and stripping turf and topsoil to a depth of about 200mm — this gives you room for sub-base, membrane and gravel without the finished surface sitting proud of the lawn. Then work in stages:

Firm the exposed ground with a plate compactor, or a heavy rammer if you are working in short sections.
Lay Type 1 MOT crushed stone in two layers of 50mm rather than one thick layer. Each layer compacts far better than a single deep one.
Water each layer lightly, then compact it until the plate stops leaving marks and the surface rings slightly underfoot.
Check the fall as you go. A gradient of about 1 in 60 — roughly 25mm drop per metre — sheds water without being noticeable to walk on.

If the ground is heavy clay, dig out an extra 50mm and put down a layer of coarse grit or a geogrid before the Type 1. On very soft ground, a woven geotextile underneath the sub-base stops the stone disappearing into the mud.

Choosing the Right Membrane

A membrane has one job: to stop soil and gravel mixing. Without it, worms and rain will work the soil upward and the path will turn into a weed-covered, muddy mess. There are two sensible options.

Woven geotextile — strong, puncture-resistant and ideal under gravel. It lets water through but holds back fine soil.
Non-woven geotextile — softer and more permeable, better where drainage is marginal but less resistant to being torn by sharp stone.

Avoid cheap black polythene. It traps water, smothers drainage and tears within a season. Whichever membrane you choose, overlap the joins by at least 200mm, and turn the edges up the sides of the excavation so the gravel cannot slip underneath. Do not stretch it tight across dips — it should follow the contours of the compacted sub-base.

Edging: The Detail That Makes the Path Last

This is the step most people skip, and it is the one that decides whether your gravel stays put. Loose gravel migrates. Without a firm edge, it will creep into borders, spread across the lawn, and thin out in the middle of the path within a year.

You have several good options, and all of them should sit on a bed of concrete or well-compacted hardcore:

Treated timber — the cheapest option. Use 100mm x 50mm timber pegged every 600mm and set so the top sits 20mm above the finished gravel.
Clay pavers or bricks — set on a mortar bed and haunched on the outside with a stiff mix. Attractive and hard-wearing.
Granite setts or cobbles — the most traditional and longest-lasting, but you will need to haunch them properly with mortar.
Steel or aluminium edging — discreet, quick to install, and excellent for curved paths.

Whichever you pick, set the edging so it stands just proud of the gravel. That small lip holds the stone in place and gives the path a crisp, deliberate line against the planting.

Laying the Gravel Itself

For a garden path, choose a gravel of 10mm to 20mm — smaller sizes are uncomfortable underfoot and prone to being kicked about, while anything larger becomes difficult to walk on. A self-binding gravel, sometimes sold as hoggin or self-setting gravel, is a lovely choice for a firm, almost paved feel, though it needs a slightly deeper layer and careful grading.

Spread the gravel to a depth of 50mm over the membrane, rake it to an even finish, and then compact it lightly with a plate compactor fitted with a rubber pad so the stones don't shatter. Leave the surface slightly crowned or falling gently to one side for drainage. Resist the urge to overfill — gravel should sit just below the top of your edging.

Keeping It Looking Good for Years

Once laid, a gravel path asks very little. Rake it once or twice a year to redistribute stone and remove leaves, which otherwise rot down and feed weeds. Top up with fresh gravel every few years as the surface settles, and pull any stray seedlings while they are small — with a proper membrane below, they will be shallow-rooted and easy to lift.

Check your edging each spring. A loose paver or a timber peg lifting out of the ground is a five-minute fix now and a ruined path in three years' time. Do that much, and you will have a path that settles down beautifully, softens the garden, and outlasts half the paving in the street.
