Our temporary flood barriers (or 'demountables') are engineered to provide similar levels of protection to permanent flood defences, but with the advantage of being fully removable when not required.

They can be supplied for virtually any configuration including arcs, closed rectangles or circles and straight runs of any length. The portable flood barrier design can be used on slopes up to 20° and can be stepped for steeper gradients.

This makes our demountable flood barriers ideal for building openings or as a continuous flood wall.

Each system is load calculated based on application and the prevailing flood conditions and can be configured for flood protection heights up to 4m. Single spans up to 3m are possible.

A four-sided detail is available for openings that may become fully submerged.

To facilitate installation in new builds, we can supply pre-formed ground plates with integral anchors for the demountable supports. Alternatively, drill and fix anchor sockets can be provided for unobtrusive fixing through finished paving.

Our demountable flood barriers can be retrospectively fitted to suitable existing foundations in which case load certified, chemically fixed sleeve anchors are used to attach the demountable supports.

Purpose designed seals that resist silt clogging and reform even after prolonged compression, together with vandal resistant covers and lockable clamps, make this flood barrier system ideal for locations where semi-permanent installation is a requirement.
