You do not necessarily have to create a substructure for your garden path, some paths can do quite well without it. However, a solid substructure can sometimes significantly increase the lifespan of a gravel path or a paved path.

The base layer is important for longevity and safety

A solid base layer also ensures your safety, because it prevents or delays the sinking and freezing up of individual paving slabs or paving stones in winter and thus the occurrence of tripping hazards. Your path will also be easier to maintain, because weeds have a hard time settling on your path. If it does happen, it's easier to remove.

Sense and purpose of a substructure:

  • prevents the path from sinking
  • Path cannot freeze up in winter
  • Lifespan of the path is extended
  • Prevent weeds from growing

How do I create the right substructure?

The thickness of the base layer depends on various things, such as the type and permeability of the soil, the stress on the path and the weather or climate at your place of residence. In severe frost, a path with a thin substructure threatens to freeze up, but in a mild maritime climate this risk is low.

Dig the ground as deep as you want the path and substructure to be high. When considering the width, also take the curbs and joints into account. Before you lay the base layer, place the curbs, ideally in a concrete foundation. Then bring in the frost protection layer of gravel. It should be approx. 10 cm high and well compacted.

It is best to use crushed stone for the leveling layer. Then there is a bed of sand about 4 cm high. You can then lay the paving stones or paving slabs, tap them firmly and grout.

Does a wooden path also need a substructure?

A garden path made of wood usually does not require a classic base layer. For a stable construction, use joist hangers or drive-in sleeves to anchor the path in the ground. Cross and longitudinal beams are used to fasten the floorboards.

tips

Always give a paved path a solid substructure, otherwise in a few years you will be annoyed by lowered stones and tripping edges on the path.
