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.

The strength of precast concrete gradually increases over time. Other materials can deteriorate, experience creep and stress relaxation, lose strength and deflect over time. The load-carrying capacity of precast concrete is derived from its own structural qualities and does not rely on the strength or quality of the surrounding backfill materials.
