L-Bloc® pre-stressed L-shaped interlocking concrete retaining wall

The L-Bloc® is the only prestressed interlocking L shape retaining wall on the market offering an ideal solution for the storage of soils, aggregates, silage, grain and many other bulk materials.

Easy installation, with unique tongue and groove system All units are designed to accommodate loading from either side of the wall. No reverse heel. Lighter weight and nested delivery

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.

Poundfield Precast Ltd manufactured a set of 36 unique and irregular precast concrete panels for our project on the Grade I Listed Menai Suspension Bridge. Each of the panels were of excellent quality and manufactured to our tight tolerance of +/- 3mm. The team at Poundfield are easy to do business with and the communication throughout the project has been very collaborative.

As a US designer and supplier of Highway Safety Equipment its important to work with someone you trust when building and supplying product in an overseas market. Working with Poundfield and in particular Tim Evans and Michael Roddy gave us that. This was critical on the high profile project we worked on during the worst of covid when travel was limited, They were very transparent and easy to work with including correcting the problems that comes with every project.

After flash flooding in August 2020, we desperately needed drainage channels that could carry the water away and allow us to rebuild the road. Having been very pleased with our previous use of Poundfield products, we naturally turned to them, and they quickly offered us a perfect solution at a very fair price, which have worked brilliantly over this very wet winter.

The quality of the precast cantilever walls units delivered to site was second to none and consistent for the 355no units produced. The delivery time scale was really tight, however Poundfield actually delivered all 355 units ahead of schedule. Communication and the level of customer service afforded was also fantastic. I will personally recommend Pound field for your precast solutions.
