We manufacture precast concrete manholes, bases, and risers for use in municipal, industrial, and private sewer systems.
Our manholes are available in a variety of diameters and heights and can be produced with eccentric or concentric cones, pipe penetrations, and cast-in connections.
We adhere to strict guidelines to meet ASTM C478 standards and comply with local engineering regulations. Need watertight boots, interior coatings, or specific pipe connections? We can tailor each structure to fit your plans and specifications.
Precast sanitary sewer products from Wilmington Precast expedite installation, minimize weather-related delays, and offer superior strength and consistency compared to cast-in-place alternatives. With a focus on quality and customer service, we help contractors stay on schedule while delivering long-lasting infrastructure solutions.
