Use & Purpose
Terralink® facing systems are used to provide suitable long term facing protection to ACEgrid® reinforced soil structures.
Where ACEgrid® reinforces the fill material to provide a stable soil mass, Terralink® provides options to protect the face of the structure from erosion, scour, UV radiation and potential localised soil slip failures of the face.
Terralink® allows such structures to be faced in a range of face slope angles from 45 degrees or less to near vertical structures.
The Terralink® system can incorporate a range of steel mesh facing panels set at an appropriate face angle to aid compaction and installation and can support a large range of erosion protection elements employing either biodegradable Erosion Control Blankets (ECBs) to permanent synthetic Turf Reinforcement Mattings (TRMs) to the use of rock fill inside the facing.
Terralink® provides the necessary long term protection and stability to the face of your structure and assists with the speed of construction and neatness and regularity of the exposed face.
Product Information/ Application
Shallow Slopes 45 Deg.
Terralink® structures with face angles up to 45 degrees from the horizontal require minimal protection to the outer facing. A permanent Turf Reinforcement Matting (TRM) is applied over the face and vegetated.
Steepened Slopes (45 Deg. to 70 Deg.)
Where an ACEgrid® reinforced soil steepened slope is to be constructed, the Terralink® facing would incorporate Terralink® corrosion protected steel mesh panels folded to the required face angle. These Terralink® steel mesh panels assist compaction and placement of a suitable TRM or biodegradable Erosion Control Blanket (ECB) inside the face. A growing medium is placed inside the TRM or ECB and seeded and maintained until vegetative cover is established.
Slopes Steeper than 70 Deg.
For steeper structures, Terralink® steel mesh panels can be incorporated in the face and backfilled with a growing medium and TRM to protect against erosion and establish vegetative cover or rock may be used inside the steel Terralink® facing panels.
