Our retaining walls are the perfect solution for separating lawns, borders and paths. They can also be used as planters. Retaining walls create a strong structural impact in gardens and outdoor spaces.

Our retaining walls offer almost limitless possibilities for creating shape and form. We always have a variety of sizes, angles and curves in stock. The prefabricated, modular system makes it easy to invisibly join retaining wall elements together.

Aluminium is corrosion resistant and is available in several colours. It can be left outside all year round without damage, even in freezing temperatures, so you can enjoy this product for many years.

Once constructed, the aluminium retaining wall is given several finishing treatments. The metal is roughened to allow better adhesion of the powder coating. This powder coating is available in a variety of colours and is applied with a strong adhesive primer. Finally, the retaining wall is finished with a hard topcoat. This ensures that the retaining wall is scratch resistant.
