Project overview

As part of a major road widening scheme, the Flex MSE® vegetated wall system was specified by the design engineers for a soil-nail reinforced slope, offering a green alternative to traditional construction methods.

Over 7,000,000 seeds were applied, via hydroseeding, onto the face of the Flex MSE® installation as part of an ambitious project run by Calderdale Council and West Yorkshire Combined Authority. The aim was to tackle congestion along the A629 in Salterhebble Hill, welcoming green infrastructure onto this heavily-trafficked roadway.

Method

After soil nails had been installed, guide rails were attached to engage with geogrids and the Flex MSE® system.

Taking 5 weeks to install, a specific seed mix was applied hydraulically once the slope was completed.

Testimonial

"Spraying the new living wall here at Salterhebble with millions of seeds and planting over 1,200 shrubs, wildflowers and trees is the final stage in creating this new vertical garden that will absorb carbon dioxide, nitrogen dioxide and reduce noise along this stretch of the route."
– Cllr Eric Firth, Deputy Chair of the West Yorkshire Combined Authority Transport Committee
