Concrete pipe and precast box producers work with suppliers to advance the technology of their products to maintain a competitive edge, while suppling rigid products for drainage systems and culverts considered to be critical infrastructure. One of the many advances in precast box and manhole production is self-consolidating concrete (SCC). Introduced to America in 2000, the concrete mix is finding its way into applications that are in demand. Structures for

implementing disaster plans and other strategies for ensuring sustained economic growth in the face of anticipated floods, coastal surges, firestorms, and extreme winter weather may be supplied with boxes produced with SCC.
