| Richard Septic Systems, Inc. introduces “C- Box” Box Culvert Sections. This product was developed to provide a substantially sized box culvert while keeping the section sizes manageable by today’s typical excavating equipment. A complete box section consists of a bottom half and top half that join at a central horizontal tongue and groove joint. With a maximum weight of 7400 pounds per any one section, placement is possible with the use of smaller, less costly equipment. These box culverts are fully reinforced to AASHTO-20 specifications. The suitability of this product for the amount of anticipated flow must be determined by a qualified engineer and/or permitting authority. |
