Reinforced Concrete Lego Block Retaining Walls
We specialize 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.
For more guidance on retaining wall design, download our retaining wall design guide. This will give you all the information you need. We can also support you using our years of experience designing and constructing retaining walls.
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.
Gravity Retaining Walls
There are two main gravity retaining wall types. Concrete block and Gabion basket. One uses concrete as it’s mass and the other stone filled baskets. Concrete is slightly denser than stone but can be less competitive. The choice depends on the driver between cost and a long life span.
Gabion basket can have a guaranteed life span of up top 100 years depending on the specification of the mesh. Concrete block walls can go far beyond this with a high quality design mix.
The principles of the retaining wall design are exactly the same. The only variable is the mass of the materials being used. We can advise you on specification and cost planning when we understand your project a little more.
Concrete lego blocks are normally cast off site at precast yards and delivered to site. The concrete mix can vary from recycled mixes to C50/C60 for severe environments and long life. The blocks are modular in design.
Gabion Retaining Walls
Gabion basket retaining walls are a gravity type retaining wall that uses stone filled wire baskets. They are very similar to our concrete block design but can be more economical.
Gabion basket retaining walls allow water to escape if large stone is used to fill the baskets. If not back drainage may be required to stop any build up of hydrostatic pressure building up behind the wall that can cause failure.
A number of materials can be used to construct Gabion basket retaining walls. The selection of the material is dependent on the budget and design life span of the wall.
The general specification and basket sizes are:
The stone fill for the baskets is important to understand as the design of the wall depends on the mass of the structure. Different materials have different mass.
Inclined Retaining Wall
There are two main inclined retaining wall types. Concrete block and Gabion basket. One uses concrete as it’s mass and the other stone filled baskets. Concrete is slightly denser than stone but can be less competitive. The choice depends on the driver between cost and a long life span. There is a third type that uses reinforced earth.
Gabion basket can have a guaranteed life span of up top 100 years depending on the specification of the mesh. Concrete block walls can go far beyond this with a high quality design mix.
The principles of the retaining wall design are exactly the same. The only variable is the mass of the materials being used. We can advise you on specification and cost plan when we understand your project a little more.
