Useful Mesh

FH Mesh (c) DAS

 

150 m2 of mesh, with 5 x 4 meter deep top anchors, 24 x 2-3m deep bolts … and a lot of hard and smart work!

Result: 15 meters along the cliff are now protected from landslides, rockfalls and erosion.

 This remedial work was done after a landslide, which took half of the barrier.

During 3 weeks, we had the pleasure to share Ben’s experience, six years team leader at Ouest Acro (French leading abseiling company), on our last work : 150square meter mesh installation and rock bolting. Ben took the chance to go to THE Match… and we have not heard of him since!

With our previous references on the same cliff, we succeeded on that tender. A team of four of us equipped in two weeks an access on that remote part of the Nevis Bluff. From the top first. Then with Heliworks delivery, we were able to built a rock fall barrier above the area to be worked on. The installation of 120m of ladders and steps bridges allowed Fulton Hogan team and ours to gain access every morning, using a double fixed line system. For the following 5 weeks: hand drilling, blasting, hand scaling and helicopter watersluicing composed the program. Thanks to our ability and abseiling  skills, Drilling & Abseil Services has been a successful part of the operations involving helicopters, heavy traffic management and work at height.
