T-WALL® is a gravity retaining wall system, consisting of modular precast concrete units and select backfill. The system is a simple proven solution for grade separation on highway, bridge, railroad, water, commercial applications, and more.
The concrete units are facing with monolithic perpendicular stems, forming the shape of a “T”. The stems internally stabilize the wall, providing pullout resistance against the lateral earth pressure exerted on the back of the facing. The result is a modular gravity structure with no mechanical connections necessary.
T-WALL units come in three sizes, each with its own advantages depending on the application, wall size, and other criteria. Each of the three unit types accommodate varying stem lengths, as well as extended-height and sloped tops for the uppermost wall course. A wide range of standard and custom architectural treatments can be applied to the front face.
T-WALL’s design methodology allows for a stem length that varies over the height of the wall. As the courses are stacked, the stems decrease in length and require less select backfill. The robust precast units efficiently provide the stability needed for gravity retaining walls with extreme height and loading.
• Easy installation with no mechanical connections
• Top units can be cast with integrated coping
• Relaxed select backfill specifications
• Variable length stems reduce backfill quantity as the wall rises
