General Information
Retaining Solutions is able to provide a range of
options to the designer, developer or contractor to effectively increase useable land area and minimise fill requirements by steepening design batter slopes, retaining general fill cost effectively and provide innovative retaining wall systems that are either temporary or permanent structures.
The use of proprietary geosynthetics (varying polymer and construction type) incorporated as layers into soil has the effect of increasing the shear resistance of the soil and allows structures to be built using such “soil reinforced” techniques in a very cost effective manner using well accepted design methodologies. Sometimes and by using similar design methodologies the soil reinforcement element may be a steel strip. These techniques will generally allow the use of “on-site” soils without the costs associated with importing specific engineered fill materials.
It is accepted to describe structures that have face angles somewhere between the angle of internal friction of the soil being retained (angle of repose) and up to 45º from the horizontal as steepened slopes, those structure that have face angles greater than 45º and up to 70º from the horizontal as reinforced slopes and those structures with face angles greater than 70º and up to 90 from the horizontal as soil reinforced walls.
The treatment at the face of the structure will largely be dependent on the design face angle of such structures. For applications of reinforced slopes and walls the facing option must be selected dependent upon the design life of the structure and the environment within which the structure will operate. Various facing options may be considered and may include a wrapped face geogrid or geotextile treatment, a wire mesh face (either vegetated or rock in-filled) or indeed a variety of readily available materials that should be selected on the basis of site specific requirements, required durability and availability. In all such applications there will need to be a connection between the structure face and soil reinforcement element such that a stable element is formed to resist local face instability and assist with compaction. Generally steepened slopes do not require facing treatments with the soil reinforcement element generally terminated at the surface of the structure. Sometimes in steepened slope applications there may need to be placed an erosion blanket on the surface to resist scour of the slope and assist in the
vegetation of the slope.
