Box Culvert - Dry Cast Concrete, Modular Design 1mt X 1mt To 6mt X 6mt, Leak-proof Joint System With Patent Protection

Concrete boxes find application in several different areas: culverts, retention tanks, vertical vaults, utility corridors and storm water drains, industrial waste and sanitary sewerage. In addition they can also be used for underground walkways, transportation of goods and services. Culverts can be either wet casted or made using dry concrete and vibrated into place. They are made with a tongue and groove and are joined together either with a gasket or a sealing compound to make a leak proof joint. Forms are modular in construction and can expand from 1mt x 1mt to 6mt x 6mt. The design also allows for variation in each wall. The box form displayed is for dry cast concrete and has been awarded a Patent by the United States Patent Office.
