A vacuum test is used to test the structural integrity of an excavated structure, like a manhole. Vacuum tests check for leaks and monitor vacuum loss, ensuring safe operation.
For temperatures below 80° F, leaks can be easily located by spraying the walls of the trench with a soap and water solution: Bubbles will form at the site of the leaks. For temperatures above 80° F, a corn syrup solution is recommended.
A failed vacuum test requires that your manhole be repaired, whether it’s through additional excavation or applying grout or a sealantl for reinforcement. If your manhole continues to fail vacuum tests after repair, the system should be replaced entirely. Need more help? Contact our trench safety experts for further guidance.
