Why Repair Groundwater Infiltration in Concrete Infrastructure?

As outlined in our previous blog posts, Mitigating I & I - An Ounce of Prevention is Worth a Pound of Cure and Spend a Little on Infrastructure Infiltration Repair, Save a LOT on Wastewater Treatment Costs, there are many dangers associated with sanitary sewer overflows, lots of funds available for infiltration repair, and many dollars to be saved by choosing to repair high-volume leaks.

How to Repair Groundwater Infiltration

All of this begs the question: How are these leaks repaired exactly? The first step is to identify high-volume leaks in manholes, lift stations, pipes, and other sanitary system components. Monitor and compare peak vs normal flow rates. Inspect the infrastructure in question and look for gushing leaks. These leaks can be repaired with a small crew of about three people. A repair crew this size typically averages about two manholes per day (depending on manhole size and proximity).

On average, curtain wall grouting an 4-foot diameter x 8-foot tall manhole requires 5 gallons of Spetec PUR HighFoamer. On average, treating joints and pipe penetrations on an 4-foot diameter x 8-foot tall manhole requires 2.5 gallons of Spetec PUR GT380.
