Concrete Retaining Walls

With options to suit everything from heavy-duty civil engineering to residential and commercial developments, our precast concrete retaining walls are designed to manage ground pressure, reduce waste, improve flood defences and streamline installation processes.

What are concrete retaining walls?

A concrete retaining wall is a structural system designed to hold back soil, manage slopes, and stabilise ground levels across built environments. These walls are commonly used in areas with uneven terrain or where elevation changes are required, helping to prevent erosion, control surface water runoff and support safe, functional land use.

What are concrete retaining walls used for?

Concrete block retaining walls are used in a wide range of settings:

Supporting roads, railways and embankments
Creating level ground in sloped landscapes
Forming storage bays and containment areas
Flood protection and vehicle security
Enhancing garden and public space designs

They’re often chosen for their strength, speed of installation and ability to accommodate varying wall heights with minimal foundation work.
