Precast concrete products manufactured in a quality-controlled environment and used with high-quality sealants offer a superior solution to watertightness requirements. Standard watertight sealants are specially formulated to adhere to precast concrete, making watertight multiple-seam precast concrete structures possible.
Precast's superior strength means that installation is often easier, quicker and less costly. It also requires less ongoing maintenance and a reduced likelihood of future problems. That means a lower total cost over the life cycle of a project.
Although precast concrete is quite heavy, nearly all other competing materials require machinery for handling and installation as well. Speed of installation is more dependent on excavation than product handling and placement. Unlike other materials such as fiberglass, precast concrete does not require the use of special rigging (such as fabric slings) to avoid structural damage.
