Rapidblocs are the first truly three dimensional movable obstacle system. The blocks allow for the creation of any shape, at any angle, at any point within the channel system. A feature as simple as a standing wave can be made larger, made glassier, moved up, moved down, moved left or moved right. Eddies can be created above the feature or below the feature or simply removed from the area altogether. This system truly gives the course operator a fully adjustable course that can be tuned, remodeled or updated.

The beauty of using this standard adjustable system is that it will allow a channel owner the confidence to know that their channel will be state-of-the-art for years to come. As the sport evolves so will the Rapidblocs and Rapidbloc configurations and long into the future a Rapidbloc channel will still provide high-tech dynamic whitewater.

RapidBlocs are manufactured from Super-Linear Polyethylene metallocene based material produced by one of the most respected polyethylene manufacturers in the UK; 'Matrix Polymers'. The use of metallocene technology gives this material the toughness to withstand the most demanding environments. It has high impact strength and ductility, is UV stabilized to minimize sunlight derogation and has a high stiffness rating and meets the ARM (Association of Roto-moulders) agreed standard.

The flexible and modular nature of RapidBlocs allows a simple additional wedge to be moulded and then slotted into position against a regularly graded trapezoidal channel side. The advantages of the system are:

• The groyne is easily movable / adjustable in position by hand
• The groyne height is variable allowing safer views upstream and improved camera views both upstream and downstream
• Fully integrated into the full RapidBlocs system
• Groyne infill is fully restrained by a locating tongue and a RapidBloc lid to the adjacent RapidBloc.

These are available on request for a specific course geometry.
