Walls That Never Fall

Who Makes It Matters!

Trading in the A.C.T. for years has taught us a thing or two about the right materials & suppliers to entrust our reputation with. We guarantee product consistency and reliability with every wall we build and only source our materials from providers that practice ethical and sustainable methods of production & supply.

Concrete Confidence

When it comes to concrete sleeper walls, we don't miss a trick! We have 17 years experience constructing retaining walls from both concrete and timber, and have discovered every single trick of the trade along the way, and it shows in our completed projects. No sagging, tipping or twisting for the life of the selected product, guaranteed!

1000 Meters Means...

Installing 1000's of meters of concrete and timber sleeper walls gives us the edge when it comes to perfect installation of your chosen retaining wall material. See what people are saying about SONMAS concrete & timber sleeper walls below!
