From excavation to weed membrane to the gravel layer – the low-maintenance path through your garden
A cleanly built gravel path structures the garden, keeps feet clean in the rain and is much easier to build than a paved path. The difference between a path that sinks into the lawn after a year and one that lasts lies in the build-up: excavate, weed membrane, compacted base layer, clean edging – and only then the decorative gravel. We show the proven build-up for walkable garden paths.
Tools
- Spade and shovel
- Wheelbarrow
- Hand tamper or plate compactor (rental)
- Rake
- Mason’s string and stakes
- Spirit level
Materials
- Crushed stone or mineral mix 0/32 for the base layer
- Weed membrane (water-permeable, min. 100 g/m²)
- Decorative gravel or grit 8/16 or 16/32
- Edging: lawn edging stones, metal edging or timber
- Lean concrete for the edging if needed
Step by Step
Plan and stake out the route
Lay out the route with a garden hose or string – gentle curves look more natural than dead-straight lines. Proven widths are 80–100 cm for main paths and 40–60 cm for secondary paths. Stake out the route on both sides with string and pegs.
Excavate
Dig out the path 20–25 cm deep, removing all roots. The excavated soil can often be reused directly in the garden for beds or ground modelling. Check with the spirit level that the base runs evenly – a slight cross-fall of 2 % lets rainwater drain off to the side.
Set the edging
The edging keeps gravel and base layer permanently in shape. Set lawn edging stones in a bed of earth-moist lean concrete and align them to the string; metal or timber edging is anchored as instructed by the manufacturer. Without edging, the gravel migrates into beds and lawn within a season.
Lay the weed membrane
Line the base with water-permeable weed membrane, overlap strips by 10 cm and run them up at the edges. The membrane separates soil and path build-up: it prevents weeds growing through from below and stops crushed stone and gravel being pressed into the ground over time.
Install and compact the base layer
Fill in 10–15 cm of crushed stone or mineral mix 0/32, level the layer and compact it with a hand tamper or – much more comfortably – a rented plate compactor. The compacted base layer makes the path firm underfoot and prevents ruts and puddles.
Spread the decorative gravel
Finally, spread 4–6 cm of decorative gravel or grit and distribute it evenly with the rake. No thicker: walking in deep gravel feels like walking on a beach. Grit (crushed grain) interlocks and is firmer underfoot than round gravel – the latter looks softer and more natural in return.
At a Glance
Safety First
- When excavating, watch for buried lines (irrigation, power cables for outdoor lighting, drainage) – clarify their location beforehand.
- Plate compactors are heavy and vibrate strongly: wear safety boots and get an introduction from the rental company.
- Work back-friendly when shovelling and barrowing – lift from the legs, split loads.
Mistakes You Should Avoid
Pouring gravel straight onto the soil
Without excavation, membrane and base layer, the gravel presses into the ground and weeds grow through unhindered – after a year little remains of the path. The sub-base is not an optional step; it is the actual path.
Skipping the edging
Without a firm edge, the gravel spreads into lawn and beds – the lawn mower will find it reliably. Edging costs little and keeps the path in shape permanently.
Too thick a gravel layer
More than 6 cm of loose gravel makes the path tiring to walk on. Better a solid, compacted base layer with a thin top layer – it walks almost like solid ground.
Common Questions
How much gravel do I need for my garden path?
Calculate area times layer thickness: for 10 m² of path with 5 cm of decorative gravel that is 0.5 m³ – at a bulk density of around 1.5 t/m³ about 750 kg. Add the base layer: at 12 cm thickness around 1.2 m³ or just under 2 t of crushed stone for the same area.
Which gravel is best for garden paths?
For the top layer, grit in 8/16 mm has proven itself: the crushed grain interlocks and gives a firm path. Round gravel looks softer and more natural but is slightly more tiring to walk on. Light limestone varieties visually brighten shady garden areas.
Does weed membrane really help against weeds?
Against weeds growing through from below: yes, reliably. However, wind-blown seeds can settle in the gravel itself – this surface weed growth is easily removed by occasional raking as long as the gravel layer stays cleanly separated from the soil.
What does a gravel path cost compared to a paved path?
DIY, a gravel path costs about €10–25/m² in materials; a paved path €30–80/m² depending on the stone, plus considerably more working time and expertise. In return, paving is more comfortable to walk on, snow-clearable and virtually maintenance-free.
Can I build a gravel path for vehicles?
For occasional wheelbarrow use, the build-up described is sufficient. For cars you need a considerably stronger build-up (30–40 cm compacted base layer) and ideally gravel grids that fix the gravel in place – professional planning is recommended here.
When is a professional worth it?
If the path should carry vehicles, lies on a slope or is to be embedded in a larger design with paved areas, steps and lighting, we are your partner. We build paths of all kinds – water-bound surfaces, natural stone paving, concrete block or stepping stones in gravel – including mechanical earthworks, drainage and a professional layer build-up. On request, we combine your new path with beds, walls and outdoor lighting into a coherent overall picture.
