Vacuum testing is the quickest and most accurate way to test the integrity of a manhole, and gives you a more reliable result than a simple water test.
If a manhole does not pass, we find the leak by spraying water on its exterior while still drawing a vacuum. Once the leak is found, we repair it with a quick-setting patching material that seals it for good.
How it works
- Vacuum drawn on the manhole
- Pass or fail against the test
- Leaks located under vacuum
- Quick-setting patch repair
