To help you succeed in your projects, here are some tips based on years of experience in the field.

What is the purpose of a retaining wall?

A retaining wall serves several important functions in landscaping. Here are its main uses:

  • Erosion control: Retaining walls help prevent soil erosion by holding back earth in sloped or unstable areas. They also protect adjacent land from the harmful effects of water or wind erosion.
  • Terrain stabilization: By creating a solid and stable structure, retaining walls stabilize sloped terrains or areas prone to landslides, reducing pressure exerted by soil and water.
  • Terracing: These walls can be used to create terraces or levels on sloped land, optimizing outdoor space for gardening, relaxation, or other uses.
  • Landscaping: In addition to their structural functionality, retaining walls add an aesthetic dimension by defining garden areas, creating decorative borders, and enhancing the appearance of your residence.
  • Infrastructure protection: In urban environments or along roads, retaining walls are often used to protect infrastructures such as roads, railways, or buildings from landslides or erosion.
