Strength The Strength of precast concrete gradually increase over time. Other materials can deteriorate, experience creep and stress relaxation, loss strength and/ or deflect over time. The load carrying capacity of precast concrete is delivered form its own structural qualities and does not rely on the strength or the strength or quality of the surrounding backfill materials.
Durability Studies have shown that precast concrete products can provide a service life in excess of 100 years. For severe service conditions, additional design options are available which can extend the life of the precast concrete product. This is extremely important when calculating life cycle cost for a project.
