Precast concrete sets the standard for utility holes. Thes e materials, while durable, require underground, on-site construction, a challenging and dangerous proposal. Why are Precast Manholes the Best Choice?Įngineers once used brick, clay, and cast-in-place concrete to build access points to sewers. Whether it is a complex job or a simple solution you need, our manholes will meet your expectations. We offer wells for light, medium and heavy-duty loading in various shapes and diameters.Ĭolumbia Precast Products provides sealed manhole systems, built to specification to include a variety of features. Dry WellsĬolumbia Precast Products manufactures dry wells for your drainage needs. There are also a variety of custom options available. Additionally, they can be single, dual or multi-compartment. Including round, square and rectangular models in single or multi-level configurations. Wet WellsĬolumbia Precast Products wet wells are available in various shapes, sizes, and styles.

We not only produce high-quality precast concrete manholes to your exact specifications, but we also do so in the most economical way possible. Quality assurance/control is verified on all aspects of precast concrete via physical tests of materials and the finished product.Materials meet American Society for Testing and Materials (ASTM) standards.It has documented long-term quality material properties.Customized higher strengths are available.Strength will be supported from the structure itself.Compression tests will verify the strength.Structural performance benefits of precast concrete utility holes also include: We feel they are the best option for a long-term solution.Ĭoncrete manholes are not only durable but non-flammable and watertight under many different installation conditions. Studies show that precast concrete manholes can last for more than a century. And unlike other structure types, concrete has increased strength over time. Concrete is an inherently durable material. Precast reinforced manholes have an unmatched reputation for its superior strength, durability, and hydraulics.
