How to Choose the Right Retaining Wall Material

You can choose the right retaining wall material by considering the following:

Desired Style

The style you choose for your retaining wall will make it easier for you to choose the appropriate material to use. For example, brick retaining walls will look good in traditional yards while concrete sleepers are ideal for modern homes.

Think About Water Drainage

Proper drainage systems in place are important to ensure your retaining walls will last for a long time. However, excess moisture can’t be fully avoided when it comes to these structures. It’s best to select a material that doesn’t break down due to the presence of water.

Retaining Wall Height

Finally, the height of your retaining wall has a huge impact on choosing the right material for it. Make sure you consult an expert retaining wall builder if you plan to install a wall that’s more than 1 metre above the ground.
