How to Build a Retaining Wall

Retaining walls are a fantastic solution to unlevel gardens. Our Gardening guru Charlie Albone shows you how! 

Retaining walls not only practical, the look great too. They’re a good way to create different, usable spaces on a difficult block.

You can split your garden into zones like entertaining areas, garden beds and lawn.

There are a number of materials you can use

- Treated pine sleepers are great for that rustic feel but brick is better for a more traditional home.
- Specialist companies can match new bricks with your original house bricks for a more seamless look.

Building a wall may seem like an afternoons work but it’s vital to get it right and its a good idea to bring in a professional. Depending on the size of the wall you may even need to consult a structural engineer.

STEP 1 - Excavate the area and dig a trench.This is for the reinforced concrete footing which will give your wall a nice solid foundation.

STEP 2 -  Then you can get to work with the brick laying. The key to the success of a retaining wall is drainage.
if you don’t get this right the water backs up behind the wall and eventually pushes it over.
Installing a sub surface drain behind the wall directs the water away, stopping any build up.

STEP 3 - Replace any soil you removed during the excavation back behind wall. Then pave or turf the flattened areas depending on how you’ve zoned your garden.

Now remember, any retaining wall over 600mm high is going to need council approval, but it's well worth the effort and could add value to your home.
