Landfill Capping Anchors - Moleigh & Dalinlongart, Argyle & Bute

Client: Shanks Group Plc
Consultant: Halcrow
Main Contractor & Anchor Installer: Environmental Linings Ltd

To provide an anchoring system that would be capable of holding a multiple layered landfill capping
solution over a steep gradient tip. An additional requirement was to provide a gas tight seal to
prevent the escape of greenhouse gases into the atmosphere and also the ingress of rainwater that
could generate ground polluting leachates.

Laid out on a staggered 3m grid pattern, the anchors were driven straight through the laid
membrane and directly into the landfill waste to a depth of approximately 1.4m. They were then load
locked by hand before the polyethylene load plate and conical wedge grip were installed and sealed
to the membrane using silicon mastic. The posidrain and UV layer were then laid and securely fixed
using the top load plate and aluminium swage.
