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.

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.

Precast concrete products arrive at the job site ready to install, which can save weeks over cast-in-place construction. Precast reduces the need for skilled labor on site and decreases the footprint. There is no need to order raw materials such as reinforcing steel and concrete, and no time wasted setting up forms, placing reinforcement, pouring concrete and waiting for concrete to cure.
