Paving for Paths and Driveways: Pavers, Stone, Concrete

The life of a garden path depends more on the base beneath it than on the top surface. Pavers, natural stone and concrete differ in load capacity, look and ease of repair.

If a paved path in the garden sinks after a few years, weeds grow between the stones and puddles linger after rain, the cause is rarely the visible surface. The quality of a path is determined by the layers beneath it. The material, in turn, should be chosen by type of use, style and future repair options: a footpath and a driveway carrying heavy cars need different solutions.

The base: invisible but decisive

Under any paving there are layers following much the same logic:

excavation: the soft topsoil is removed and the subgrade is compacted;
geotextile: keeps layers from mixing and spreads loads over weak soil;
a gravel or crushed-stone sub-base, laid in layers with each compacted by a plate compactor;
a bedding layer of sand or fine crushed stone so the surface sits level;
the surface layer.

Sub-base thickness depends on the load. A footpath needs a relatively thin base, while a driveway and parking area require a thicker, well-compacted base. On clay and damp soils, a drainage layer is especially important.

The surface is laid with a slight fall so water runs off. Water is directed toward a lawn, a channel drain or a rainwater inlet, not toward the foundations of the house. Edge restraints stop the paving spreading sideways; without them, pavers gradually drift apart.

Concrete pavers

Concrete block pavers are a common choice for garden paths. They come in many shapes, colours and textures, and since they consist of separate units, they can be lifted and relaid when access to underground services is needed. If settlement occurs, only that area is repaired.

For vehicle loads, thicker pavers and a suitable laying pattern are chosen: some patterns interlock the blocks better and resist movement under tyres. Joints are filled with sand, and special jointing sands are available to reduce weed growth.

Clay brick pavers are laid on the same principle and give a warmer-coloured, classic look.

Natural stone

Natural stones such as granite, basalt, limestone and travertine give a garden a rich, natural appearance and are very long-lasting when chosen correctly. When choosing, pay attention to the stone's density, water absorption and surface finish.

Polished stone becomes slippery outdoors when wet, so flamed, sandblasted, bush-hammered or natural cleft finishes are chosen for paths. Porous soft stones are more prone to staining and wear, and hard stones are preferred for driveways. Thin slabs can be bedded in adhesive mortar on a concrete base, while thick stones and setts can be laid on a sand-and-gravel bed.

Concrete surfaces

A cast concrete path can be a fast, strong solution. The surface is broom-finished, pattern-stamped or exposed-aggregate for a decorative look. On large areas, control joints are cut to accommodate thermal movement; otherwise the concrete cracks randomly.

Concrete's weakness is repair: when a pipe needs to go underneath, cutting it out and hiding the repair is difficult. Underground services should therefore be run in protective ducts before the concrete is poured.

Gravel and mixed solutions

Gravel is the simplest and most permeable surface, suited to garden paths and informal areas. But it is hard to push a wheelbarrow over, and it spreads to the edges and into the lawn. Cellular plastic or concrete grids hold gravel in place and can even create a "green parking" area with grass growing through.

Mixed solutions are common: two stone strips for car wheels with gravel or grass between them; a main path of pavers with stepping stones for garden paths.

Quick checklist for choosing

Will cars use the path? Set the base thickness accordingly.
Has the direction of water run-off been planned?
Is the surface slip-resistant when wet?
Does the material's colour suit the facade and terrace paving?
Have protective ducts been laid for cables and pipes that will run underneath?
Can the paving be lifted and reinstated if repairs or additions are needed later?
