Maximise your land with a quality low retaining wall. For low retaining walls under 1.2m in height, we have developed a strong standard design that is customised as required for your site. For heights over 1.2m, the retaining wall will be custom designed, due to the higher loads placed on it. A retaining wall has to be strong enough to hold the load of soil pressing against it – this is what determines the size of the poles and the thickness of the timber to be used. The footings or foundations however are what anchors the wall and is therefore the most important, because if they are weak the wall will fall.
