Precast concrete products can provide a service life in excess of 100 years, and where severe conditions preclude service there are options available to further extend the life of the precast concrete product. Precast concrete also resists most substances. While no material is completely immune to attack from aggressive chemical agents, our precast products can often be designed to resist corrosion in specific applications.
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.
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.
