Storage of hazardous material, whether short-term or long-term, is an increasingly important environmental issue, calling for containers that not only seal in the materials, but are strong enough to stand up to natural disasters or terrorist attacks. Precast concrete products can be designed in all sizes and shapes to meet exact specifications to protect both the environment and the population. Products include: fuel storage vaults, spill containment products and a variety of other hazardous material containment elements.
