Reinforced Block Retaining Walls

We specialise in the design and installation of reinforced block retaining walls. These are the most economical solution for many applications.

The wall construction is very fast when comparing with traditional construction. The wall is reinforced using bars that thread through the blocks into the foundation. The foundation and the wall act together as a cantilever giving the structure strength and the ability to restrain the retaining material.

Reinforced Block Retaining Wall Design Guide Table

The design table below shows an example of the wall heights. We can design walls for many civil engineering problems using reinforced block retaining walls.

Reinforced Block Retaining Walls
Cantilever Retaining Wall

The design table above presents for the reinforced block retaining walls are Indicative designs based upon a base material with allowable bearing pressure of >200kPa.

The retained material is assumed to be well graded, granular backfill with back of wall drainage or weep holes to relieve hydrostatic pressure.

All indicative information presented in this table is based upon assumed loading and ground conditions and may be subject to change following detailed, site specific design.

Reinforced Block Retaining Wall Sizes

Depending on the height of the wall, the walls are built using either a RWS – R 600 or RWS – R 800 blocks.

RWS – R 600 Blocks are used for wall heights from 1.8m to 4.8m as you can see in the table above.

The dimensions of this block are 600mm wide x 800mm high x 1800mm, 1500mm, 1200mm, 900mm and 800mm long.

The walls are built to a modular of 600mm.

Each standard block builds 1.08 m2 of the wall.

The blocks are made form high strength (50N/mm2) concrete, using natural stone and aggregates. This allows the blocks to have high levels of durability.

As each block has its own lifting pin cast into it – you can easily change the way in which they are configured without the need for specialist lifting equipment or grabs.

Patent Pending – The reinforced block are patent protected and are manufactured under licence.


RWS – R 800 Blocks are used for wall heights from 5.6m to 6.4m as you can see in the table above.

The dimensions of this block are 800mm wide x 800mm high x 1600mm, and 800mm long.

Each standard block builds 1.28 m2 of the wall.

The smaller lengths allow for bonding. The walls are built to a modular of 800mm.

The blocks are made form high strength (50N/mm2) concrete, using natural stone and aggregates. This allows the blocks to have high levels of durability.

As each block has its own lifting pin cast into it – you can easily change the way in which they are configured without the need for specialist lifting equipment or grabs.

Patent Pending – The reinforced block are patent protected and are manufactured under licence.

Which retaining wall type is the most economical to build? We have written an article on retaining wall price comparisons. The article details the types of retaining wall and gives you a price of each type for comparison. 

Retaining Wall Design Service

The design of a retaining wall requires knowledge of the retaining material, the water table, the ground bearing capacity and any site constraints. The design requires a ground investigation and a structural engineer to ensure the design is fit for purpose.

We offer a full design service from carrying out the ground investigation to final working drawings.
