Turkey Brook Landslip

After a large tree fell into the Turkey Brook at Forty Hall Country Park Estate, the bank of the brook was scoured out by fast flowing water.
Enfield Council contacted us to help with the revetment work and we came up with an unusual solution involving willow planting, gabions, infilling with soil and coir matting to keep the whole thing in place.
All looks peaceful and calm in this photo taken in June but in winter when the works were carried out, it was necessary to keep the water away from where we were working.  A temporary silt barrier was constructed from an impermeable curtain woven with a geotextile and floating oil boom, secured to the base of the riverbed.
The willow is growing well and the bank is much more secure than before - the clients are very happy with the result.
