Get in touch Fact sheet

The L-Bloc® retaining wall solution comes in 10 different sizes

Standard wall units are produced up to 3.65m in height, (weight 2.2 tonnes), but greater heights of up to 6m can be supplied depending on loading conditions and use. All units are designed to accommodate loading from either side of the wall if required.

Designed in accordance with BS8110 (Parts 1&2) ‘L’ blocs above 2.4m have a prestressed concrete stem. This offers the advantage of a much lighter unit than a conventionally reinforced ‘L’ shaped wall, with the added benefits of reduced transport and installation costs.

Experience has shown the units can withstand significant misuse by mechanical plant used to move retained material. However, as with any relatively thin walled concrete structure, they will suffer damage with persistent and negligent striking by mechanical plant.
