Aquacast River Bank Erosion Protection and Retaining Walls

Aquacast was originally designed for river bank erosion protection and flood defence walls but can also be used for retaining walls. The blocks are constructed using a fibre reinforced concrete cast in a W shape. The design gives the Aquacast block lots of flexibility.

Aquacast blocks can be used for domestic garden walls and flood defence as well as commercial use.

The slot design within the block provides structural holes for a piling option. Aquacast blocks are very useful for rapid construction applications including, land slides, support walls for subsided road’s embankments and support for collapsed sea defence walls.

Aquacast Retaining Wall Design Guide

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

The design uses well graded, granular backfill with the back of the wall having drainage to relive 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.

Aquablock Design

The W shaped Aquablock is 800mm long, 400mm wide and 125mm deep. Each block weighs 85kg and can be lifted using a small lifting grab. They are made from fibre reinforced concrete to give them high strength and durability.

The block are designed so they can be placed one on top of each other and bonded or opposite each other forming a pocket for reinforcement. The block can be laid at ninety degrees from each other and to form a zig zag pattern. Watch the video to see how they can be put together.

Compare Prices of Retaining Wall Types

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. 

Aquacast Retaining Wall and River Bank Erosion Protection 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.
