Since the City of Florence had never used this application before, they were interested in this test to see if the quality was acceptable for additional future repairs.

Ground Works Solutions sealed all leaks and installed a one-inch thick, structural, centrifugally cast, cement liner for the full depth of the five manholes. The liner also included ConShield, a concrete additive to resist hydrogen sulfide corrosion. Thiobacyllus bacteria forms on the walls of sanitary structures due to the presence of hydrogen sulfide. This bacteria produces sulfuric acid that…
