What are the differences between a decorative wall and a retaining wall?

Decorative walls are purely aesthetic. While they serve a purpose and are functional, they remain primarily ornamental in your landscaping. A retaining wall, as its name suggests, must support and contain the earth in front of which it is built. It must therefore be able to withstand the weight and pressure of the earth, especially during severe weather. This type of structure requires a proper foundation and excellent drainage to prevent cracking and subsidence under water pressure. Installing a geotextile membrane and a perforated drain, using suitable crushed stone, and ensuring proper compaction are all elements that will guarantee the longevity of your project.
