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 is one of the most versatile and sustainable building materials available for today's fast-paced, environmentally conscious construction. 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.
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.
