Gravity Retaining Walls
Gravity retaining walls depend on the weight of their mass to resist pressures from behind and are ideal for retaining walls up to 1.25 metres high.
Suitable Secura Products include Secura Lite, Secura Minor, Secura Major and Secura Grand.
Reinforced Retaining Walls
Geogrid is the most commonly used material to reinforce retaining walls above 1.25m metres. It is a mesh-like material installed in layers between the blocks and covered with backfill which is then compacted. This creates a soil mass structure behind the wall, resisting the forces acting against it.
Suitable Secura Products include Secura Major and Secura Grand.
Concrete Backfill
Concrete is poured into the space behind the blocks and the excavated space, it then acts as a homogenous mass designed to be a mass gravity wall.
This method generally reduces the space required behind the retaining wall by around half compared to that required for geogrids. It is a more expensive option so is only specified where space is limited.
Suitbale Secura Products include Secura Major and Secura Grand.
Duckbill Anchor
This system involves a specially designed anchor, linked to high yield tie bars, being driven into the ground. A tension load is then applied to the wire connector and the anchor is locked in place. The tension wire is then tied around the rope connector within the recessed walling units.
This method is most suited to projects where there is little or no room for excavation behind the wall.
Suitable Secura Products include Secura Major.
