Retaining Walls are engineered structures designed to restrain soil to unnatural slopes. They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered to create a safe stabilized area to utilize.
The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction and the cohesive strength of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes. TerraScapes can provide required design drawings prepared by a licensed engineer for retaining walls as well as, Soils and compaction Testing, Engineers’ Letter of Certification and Permitting can be provided if required by local Building Codes.
Segmental retaining walls are modular block retaining walls used for an array of applications. These walls are designed and constructed as either gravity retaining walls (conventional) or reinforced soil retaining walls. The system consists of dry-cast concrete units that are placed without mortar (dry stacked) and rely on their unit to unit interface and mass to resist overturning and sliding. SRW units are manufactured in conformance with industry standards to assure that units delivered to a project are uniform in weight, dimensional tolerances, strength, and durability—features not necessarily provided in site cast materials. Unit to unit interfaces include friction, shear elements, and interlock. The systems may also employ soil reinforcement that extends into the backfill and allows for the construction of walls with significant height, in excess of 50 ft. that could not be accomplished with the units alone.
