With walls, differences in height in the garden can be compensated for wonderfully and at the same time secured against slipping. Various materials are available for this purpose, so that the retaining wall can also be perfectly matched to the garden design. What you need to consider when building a garden wall on a slope and how to do it, you will find out in this guide article.

Dry stone walls are very popular for intercepting low slopes

Which materials are suitable?

Embankments can with:

  • dry stone walls,
  • concrete walls,
  • gabions,
  • plant stones,
  • Wooden or concrete palisades

to be attached. Skilfully planned planting provides additional support and gives the hillside garden its typical flair.

How should a retaining wall be constructed?

If the garden wall is to protect an embankment from erosion or gravity, it must be extremely stable. Therefore, it is advisable to seek professional advice but a height of one hundred centimeters.

From a height of two meters, it is even required by law to call in a structural engineer. You should also inquire before planting the hillside garden whether you need to obtain a building permit.

Stabilization of the slope

If the gradient of the embankment is less than seven degrees, it is sufficient to secure the slope by planting deep-rooted plants such as summer lilac or broom.

If there are larger height differences, you need a professional concrete foundation, as the garden wall has to absorb enormous pressure. A so-called gravity wall is often necessary, which should be installed by an expert.

This garden wall must remain stable even in heavy rainfall with a lot of seepage water. This necessitates backfilling with gravel and, depending on the soil conditions, good drainage. It is therefore essential that you get advice from a specialist.

Plant rings for slope attachment

Planting stones are open at the top and bottom, made of concrete and have an indentation to stabilize the slope. This variant of the garden wall fights a bit against the dusty image. However, it is the case that smaller embankments can be easily stabilized with this self-erected garden wall.

Method:

After the foundation has been laid, the stones are stacked slightly backwards from row to row. This gives them the stability they need. The front part of the stones remains open and is filled with soil. The wall is then planted with cushion perennials or herbs.

tips

If you only have to secure a small embankment, a natural stone wall is a good choice. This not only underlines the natural flair of the garden, it is also a habitat for many beneficial insects such as bumblebees, wild bees and lizards.
