Tieback retaining walls are a practical and economical solution when a permanent retaining wall is to be built in a cut situation, particularly when it is desirable to leave a road, structure or other feature behind the wall location undisturbed. While excavation behind the wall face is not required to construct a permanent tieback retaining wall, an easement for the tiebacks is required.
These structures are designed to last for a specified period of time (often 50 years). For this reason, the wall environment including the soil and groundwater are evaluated to determine their potential for corrosion, and the tiebacks and facing connections are designed accordingly.
To insure the longevity of the wall, the facing is usually concrete. The wall facing can have any number of aesthetic treatments including form lined precast or cast in place concrete, and sculpted shotcrete.
