Plastic Encapsulation System Against Corrosion

Permanent ground anchoring systems must be protected from corrosion through their entire design life. Long term corrosion protection if achieved by encapsulation the steel anchors. The thick (2mm minimum) IDE sinusoidal HDPE corrugated sheathing with glue-lined heat shrink end caps provide the required level of corrosion protection for permanent anchors. As part of our complete ground anchoring system, we provide internal and external spacers that match our bar and sheathing diameters. We also supply screw-type couplers to join sheathing segments to minimize waste.
