The most commonly used barrier type is the blast wall. In some cases a main function of the blast wall is to limit the size of the explosive cloud; in other cases, its purpose is mainly to reduce the impact of a potential explosion, by shielding the structures outside the wall from excessive overpressure loading.

What is a precast wall?

Precast Concrete Wall Panels Precast concrete simply means concrete cast into a reusable mold or “form,” which is then cured in a controlled environment, transported to the install-site and lifted into place. Our precast wall panels make a beautiful addition to any plan.
