This L shaped pre-stressed interlocking concrete panel offers an ideal solution for the storage of soils, aggregates, silage, grain and many other bulk materials.
Contact Fact SheetStandard 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.
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, levelled and ground fixed 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.

‘Thank you for the excellent way your sales team has co-ordinated with me, the buyer and proprietor of Jeff Townsend, on our recent orders.
Your quotes on your L-bloc and Alfablocs, which we regularly use on various contracts on recycling sites, are very competitive.
Once the delivery schedule had been agreed the deliveries were prompt and on time. We were constantly kept in touch by your delivery drivers and despatch office so that we all knew what was happening’.
Jeff Townsend, Proprietor - Jeff Townsend
I wanted to pass on my thanks and comments regarding your delivery and service over the last two days. Both of your operators that attended our site were extremely courteous and helpful in assisting with the offloading of the floor beams.
As you are aware, site access is tight but with their help the process ran smoothly.

Allows the concrete retaining wall system to be continuous and ‘gap’ free. The corner section is the perfect solution if you are trying to achieve a stand alone storage area where the corner units are placed at right angles. The concrete corner section is designed to fill the gap for both internal and external use (i.e. foot in, foot out).
To secure the corner sections in place a horizontal connecting strap can be attached to the corner unit to provide additional support against the load. The corner bracket will prevent movement and slippage of the corner section.
The ground fixing kit is available to provide an even more secure surface attachment. If you are looking to create a more permanent structure, either immediately or at a later point in time, the L-Bloc® is designed to allow for ground fixing. The kit comes with all required steel and bolts, together with a tube of resin. Resin applicator sold separately.
The lifting attachment allows for easy and safe lifting, with cast in anchor points to create an equilibrium thus enabling a level lift. Designed to specific requirements of the L-Bloc® design, the lifting attachment is the most efficient method of installing the units.
The tongue and groove design of the L-Bloc® allows for a seamless join to the units. However to achieve an effective seal we can provide sealant which can be applied between the units. A sealant applicator is also available, and is sold separately.
This product is professionally designed and the performance has been calculated by our structural engineers. All applications, and use of our products, must be in line with our guidance, based on the specific capabilities, which is advised by our trained sales team.

Our experienced sales team is always on hand to help and advise you on the features and benefits of all of our retaining wall products and would be more than happy to help you discuss the wide variety of options on offer.
