Geogrid Reinforced Soil Walls
Geogrid reinforced walls are gravity retaining walls with an expanded width (commonly known as “Reinforced Fill Zone”) created by the placement of geogrid behind a column of segmental facing units. The combination of segmental units and geosynthetic layers act together creating a coherent mass to resist the destabilizing forces generated by the retained soil and applied surcharge loadings... more info.
Steel Ladder Reinforced Soil Walls
Steel (in-extensible) reinforced walls are high performance, mechanically stabilised earth retaining wall systems developed specifically for taller walls (highway walls), walls with heavy surcharges, piled bridge abutments and walls where loads or structures are within the “active zone” directly relying on positive mechanical connection strengths... more info.
No-Fines Concrete Gravity Walls
The use of “No Fines Concrete” is an effective alternative to that of traditional geogrid reinforced structures. This solution is also advantageous when walls between 1.6m to 3m in height are required close to property boundaries or adjacent to rock cuttings. This solution reduces excavation costs and is fast to erect compared to the geogrid solution... more info.
Massbloc Walls
The Rocla MassBloc® retaining wall system comprises large, permeable concrete blocks weighing around 1.8 tonnes that are interlocked by a nib precast into the base of each unit. This means permanent retaining walls can be deployed rapidly to counter erosion, land slippage or wave energy. Rocla MassBloc® retaining walls are economical, easy to transport... more info.
Loc-A-Bloc™ Walls
Loc-a-Bloc™ is a retaining wall system aimed at the higher end of the retaining wall market because of its engineering capabilities and architectural aesthetics, with the appearance of sandstone and the structural properties that natural stone cannot apply. Loc-a-Bloc™ engineering capabilities are such that heights of between 0.6m to 9m can be achieved... more info.
Earth Anchored Walls
The use of earth/rock anchors is a cost effective retaining solution when bulk excavation for traditional geogrid reinforced segmental walls is not possible or impractical. Essentially the earth anchors are driven back into the residual soil to the required depth (typically past the predicted failure surface). All earth anchors must proof tested up to 90% of yield strength... more info.
