![]() The Inverted T-WALL design can accommodate a more narrow wall footprint, however as with all retaining wall geometries, * the Geotechnical Engineer should determine the minimum base width (stem length) required at the bottom of wall to provide an adequate safety factor for global stability. A conventional T-WALL structure has shorter stem lengths on the top, whereas an Inverted T-WALL starts with shorter stem lengths on the bottom. As the courses are stacked, the stems change in length and require less select backfill. T-WALL’s design methodology allows for a stem length that varies over the height of the wall. The robust precast units efficiently provide the stability needed for gravity retaining walls with extreme height and loading. A wide range of standard and custom architectural treatments can be applied to the front face. Each of the three unit types accommodates varying stem lengths, as well as extended-height and sloped tops for the uppermost wall course. T-WALL units come in three sizes, each with its own advantages depending on the application, wall size, and other criteria. ![]() The result is a modular gravity structure with no mechanical connections necessary. The stems internally stabilize the wall, providing pullout resistance against the lateral earth pressure exerted on the back of the facing. The concrete units are facing with monolithic perpendicular stems, forming the shape of a “T”. The system is a simple proven solution for grade separation on highway, bridge, railroad, water, commercial applications, and more. T-WALL® is a gravity retaining wall system, consisting of modular precast concrete units and select backfill. The Reinforced Earth Company is excited to add T-WALL®, formerly of The Neel Company, to our list of proven retaining wall solutions.
