Channel and slope protection using Erosamat and Erosaweb

The Taylor Wimpey Barratt Homes development on Henthorn Rd, Clitheroe presented the project consulting engineers with an interesting challenge. Running across the development was an existing water course which required realigning and reprofiling. Part of the watercourse was channeled through a culvert with the remainder left as an open channel to form a green amenity area within the development In order to maximise the available land for the development of housing the slopes of the culvert bank were to be as steep as permissible whilst taking into account the safety of the new residents.

Erosamat Type 3 comprises a three dimensional structure of entangled filaments to create a long lasting, environmentally friendly, flexible erosion control mat which, in combination with vegetation, forms both an effective erosion control surface and a vegetative root reinforcement layer

The bottom of the flow channel required a different solution, one capable of withstanding the high flows within the watercourse. Here the consultants specified Erosaweb infilled with graded crushed stone engineered to withstand wash out by running water. Erosaweb is a three dimensional honeycomb structure designed to strengthen infill materials by containing them within its open structure. In water flow channels it dissipates energy by containing the granular fill and producing a rip-rap type performance. A holistic design combining both ABG products allowed the engineers to achieve the desired visual effect for the channel whilst allowing the groundwork contractors to quickly and simply install the required protection.
