(952) 922-0027Reliable precast concrete manhole solutions for sewer management and access.
Why should you incorporate precast concrete manholes in your next sewer construction project?
Precast concrete manholes are a critical component to any sewer system and provide an access or observation point for pipe junctions. With a properly designed and sized precast manhole, it is possible to create a water-tight space that allows for inspection, maintenance and future upgrade of a sanitary or storm sewer system.
The advantage of using precast manholes is that installation is fairly simple. In contrast to poured in place structures, precast installation can be completed with simple machinery and a small group of professionals.

Precast Manhole Shapes
Round Structures
The purpose of a precast concrete manhole is to provide an intersection point and access to sewer lines below. Round manholes offer flexibility in the angle of intersecting pipes as well as design advantages. The wall thickness of round manhole structures doesn’t increase nearly as much with increasing depth due to the inherently strong nature of round structures.
Rectangular / Square Structures
Square or rectangular precast concrete manholes also serve as an intersection and access point similar to round manholes. The primary advantage of square and rectangular manholes is the ability to accommodate larger pipes intersecting at 90 degree angles without significantly increasing the overall size of the structure.
