Garden retaining walls are retaining walls built and explicitly designed for gardens or small landscape projects within the house. They are typically constructed from stones or bricks and designed to help manage soil erosion or uneven landscapes.
While retaining walls are highly functional, they can also elevate the entire look of your garden, giving it a unique aesthetic.
If you plan to get one, we’ve put together a detailed list of the best garden retaining wall based on popular demand.
Steel Retaining Walls
Steel retaining walls are a durable and versatile option for modern gardens. They provide a unique look that blends with the garden scenery and gives it a contemporary look. Steel sleepers are the best in the market right now.
They provide the beauty of regular brick walls, contrast beautifully with the flowers and leaves in the garden, and are super durable. The great thing is that steel sleepers can be installed by even the most novice DIYers, and they are sustainable.
Gabion Retaining Walls
If you’re into building with eco-friendly materials, Gabion garden retaining walls may be just what you’re looking for. This wall can be customized to fit your unique preferences, and because they are built with wire cages, Gabion walls usually offer a good drainage setup.
A lot of people fill up their Gabio retaining walls with stones and pebbles; it all adds to the beauty and overall functionality of the wall. They are almost similar to steel sleepers in terms of the finished look—edgy, unique, and beautiful at first sight.
- Gabion retaining walls are even more beautiful when you combine different sizes of stones and add pieces of glass to give it a pop of color.
Mosaic Garden Retaining Walls
Mosiac garden retaining wall designs have been in existence for centuries. If you want a less edgy but fun look for your garden, this may be a great choice. They’ll also add a splash of color that blends excellently with the greenery from your garden.
These gardening retaining walls are mostly designed with traditional retaining wall structures and finished with decorative ceramic tiles, glass pieces, or recycled materials.
How Deep Should a Garden Retaining Wall Be?
Whether you’re building a steel sleeper retaining wall or a gabion, knowledge of how deep your foundations should be is essential. There are some major things to consider before we conclude;
- Soil type
- Wall height
- The material to be used for the retaining wall
- Drainage
Considering these factors, the standard depth for small garden retaining walls is 6 to 12 inches. For medium walls, it is 1 to 2 feet, and for tall walls (more than 4 feet high), it usually goes above 2 feet, so professional advice is encouraged.
