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.
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.
