The reinforcement design in our L shape retaining walls, are ideally suited for projects where the retained material is on the toe side.

Depending on the application & site ground conditions, the units do not require fixing to a reinforced concrete foundation and can be installed directly onto a Type1 sub-base & sand/cement blinding layer.

If you are installing onto an existing foundation, or cannot backfill in front of the unit as shown below, a resin anchor system can be used to prevent sliding.

For situations where you will require to retain material on the back of the wall or for double load scenarios, (retaining on both faces), please refer to our DLF10GS product.

Our C60/75 self compacting concrete mix provides the precast elements with an excellent class A finish to all visible faces.

In addition to this we are able to offer some bespoke features to further enhance the appearance of the L shape precast retaining wall units:

Sloped Top – A maximum sloping top to any one precast element of 500mm per 2m, (or 1 : 4 gradient) can be achieved. This finish is particularly popular when constructing staircases or ramps & for varying levels on site.

Stone Box – The hybrid gabion retaining wall system, combines the speed & cost benefits of a precast retaining wall and the aesthetics of a gaboin basket.
