Retaining Wall – L-Bloc®

The Poundfield Product L-Bloc®, which was launched in 2003, is the only pre-stressed interlocking L shape concrete panel on the market and it has many advantages over normal precast L shape Walls.

Prestressed ‘L’ blocs offer an ideal design solution for the retention/storage of soils, aggregates, silage, grain and many other bulk materials. Standard wall units are produced up to 3.65m in height. Greater heights can be supplied depending on loading conditions and use.

All units are designed to accommodate loading from either side of the wall. 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.

Manufactured from high strength C60 concrete with minimum 30mm cover to Steel, the units provide excellent durability against most exposure conditions (up to very severe conditions in accordance with BS 8110). The units require a suitable concrete foundation that has been designed by a qualified Engineer to ensure ground bearing and stability requirements are met.

Units are then lined and levelled and bolted down through the preformed holes in the base using resin anchors. A unique tongue and groove joint down each side prevents misalignment of the walls either during installation or due to uneven loading. It also provides an ideal joint detail which can be sealed if required.

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.
