Engineered Steel Versus Precast Concrete Manholes

Unlike concrete, steel manholes are watertight, install faster, and last longer. Concrete is prone to cracking and will denigrate over time. This enables ground and rain water to work their way into manholes through open cracks, joints, and access points. Over time this can lead to downtime and costly maintenance. Faster installation time Less space requirements/smaller footprint Lower cost to maintain over the life of the unit

Manhole inspection

When you’ve installed and inspected as many manholes as we have, you know when an underground heating and cooling system is performing optimally and when it isn’t. At the earliest detection of a problem our team can help you find and resolve issues quickly. We will inspect the entire manhole and check all of the pipes and valves. Early resolution of these issues can help avoid downtime saving you money and critical exposure.
