West London Dike

West London Dike

Risi Stone Systems

London, Ontario

As part of the large-scale reconstruction of an existing dike system along the Thames River in London, Ontario, 200m (1,000ft) was replaced with a new 8m high (26ft) DuraHold wall. The wall needed to be able to withstand rapid flowing hydraulic conditions of extreme two year and 75 year flood events which have the potential to completely submerge the full height of the wall. DuraHold was the ideal choice because its smooth surface reduces drag effect from flowing water, and it has a proven track record of structural stability. As well, DuraHold offers the benefit of installation efficiency in straight or curved applications thanks to the availability of tapered wall units. A pathway running alongside the Thames River was incorporated into the layout atop the new DuraHold wall. The south end of the wall was terraced, allowing the pathway to extend down under Queens Avenue and Kensington Bridges, and connect to Riverside Park.
