Instant Foundations screw piles can be installed as earth reinforcement. Once installed anchors can be directly load-tested using hydraulic jacks. Anchors can penetrate most strata including low strength rock.
The speed of installation of screw pile anchors greatly exceeds that of traditional ground anchors. They can be installed through temporary sheet piling or fixed to concrete plates which bear against the embankment face. Anchors can be pre-tensioned or de-tensioned and/or removed at a later time.
