Thinshell Precast is a durable, watertight panel system that has been used for all types of construction projects. Thinshell Precast is a composite panel system that is typically designed with a 2¼” thick concrete skin that is attached to a structural frame. The overall thickness is a minimum of 7½”. This light-weight panel system that averages 35 pounds per square foot can be cast with a wide range of colors and textures. Panels are normally given a light, medium, or heavy sandblasted finish. Utilizing both light and heavy sandblasted finishes in the same project is a commonly used design option to achieve two colors. Custom form liners can also be made to simulate other building materials such as wood, stone, or brick. After the first pour of concrete is placed and consolidated, the structural frame is then placed into the form. The frame is typically made from 4″ deep tube steel. Galvanized L or T-shaped pins are welded to the structural frame and a welded wire fabric is attached to the end of the pins. Once the frame is secured in place the back pour is then placed and troweled to ensure complete coverage of the embedded wire fabric. The following morning each panel is stripped from its form and receives its approved sandblasted finish.
