Engineering Paddler Designs


Working with Halcrow consulting Engineers on a wide scheme of Thames weirs safety improvements an opportunity presented itself for an ideal and low cost solution to provide a real recreational opportunity at the Mapledurham weir site.

During scheduled works to replace an old weir structure with a radial control gate a number of unistrut rails were quickly, easily and discretely inserted into the concrete base slab immediately downstream of radial gate.

Upon completion of the engineering works a trial was undertaken to demonstrate the ease and speed with which the RapidBlocs system could be installed and a paddlesports feature formed. Tests on downstream velocity were undertaken along with a procedure for installation, removal and operation drafted. The site demonstrates the ease with which some forethought can allow a very cheap addition to existing engineering works can derive an excellent paddlesport feature that does not detract from the river structures primary function.
