Since 1982, Tru-Contour, Inc. has become one
of the leaders in the precast concrete industry, providing supplies for producing sanitary sewer manholes, catch basins, and grade rings. The Tru-Contour Invert Forming System has been a staple in the industry for 20 years. Our invert forms are still the most effective way to form inverts in a secondary pour situation. The versatility of the system is unmatched. New products are being developed to complement the invert system to provide even further accuracy in manhole construction. This site was designed to allow you to explore the benefits you could experience through the Tru-Contour precast equipment.
