Manhole Vacuum Testing
Manhole vacuum tests are quick to set up and run. It takes twenty minutes or less to test a new manhole under normal conditions. Any leaks that may exist are detectable immediately, unlike water testing which can be very time consuming. We set plugs in the main and any services that are located within the manhole place a steel test plate or bladder type plug on the 24” – 42” opening that exists on the surface then with special equipment vacuum out all the air to a negative 10mm

Manhole Rehabilitation
Since Manholes suffer from a variety of problems, from minor leaks to major failures, we offer an assortment of methods to accurately repair them so that they can pass vacuum testing and do not allow ground water to infiltrate inside. Each solution is tailored to overcome the particular problem that is encountered. Often times, more than one method is needed to fix an issue with a failing manhole.
