Bespoke Precast Concrete

Aquacast Flood Defence System

The Aquacast Flood Defence System is an innovative interlocking retaining wall system for use in flood defence and riverbank reinforcement.

By overlapping at half block lengths in alternate directions the reverse slots provide a rigid format with a uniformly pitched centrally located aperture. These cavities can be filled with various materials to form permanent or temporary constructions. Steel pilings can be used through the centre of each cast to add additional reinforcement and strength when required. The blocks can be used below the water level rising above water level as needed.  Further blocks can be added to or taken away from the original structure at a later date if required.

The Aquacast blocks have been tested at the Flood Chamber by Aquobex to the PASS standard which is sponsored by the Environment Agency.

Installation of the Aquacast Concrete Flood Defence System

It is advised that prior to the installation of a permanent structure or any structure above 1 metres tall a site survey and ground density analysis should be carried out by a structural engineer. It maybe required to apply a foundation material depending on the basic conditions of the ground and advice can be made on additional reinforcing material for the structure.

The wall system can be used with various water retaining membranes and materials to ensure water is retained. The system is flexible and can be used with a number of different jointing systems.
