Manhole Leaks

dayexco

i have a manhole that the invert is 9' into the water table, had a joint failure on the bottom manhole section. have any of you ever used that stuff that comes in a caulking gun tube, you drill a hole through the manhole near the leak, shoot the stuff into the hole, and it seals the leak up? if so, what manufacturer do you prefer, have the best luck with.

Look at product AV-202- it's the bomb. We've had reason to use it extensively in high head conditions with great success. Avanti will sell it direct to you by the case. I'll tell you tommorrow the injection technique and hole size we've had the best luck with.
