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 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.
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.
