Allied conducted an Emergency repair on a failed sewer line for a local municipality. Due to the unusual location of the sewer, we were called for a “No Dig” approach. Erosion had caused a large void under the sewer infrastructure. After installing a cured in place pipe inside of the existing sewer, we then filled the large void with a flowable fill. After the fill was set we repaired the manhole structure and used an injection grouting method to fill all remaining voids around the structure. The finished product is a new sewer with no leaks and a manhole structure that is solid and good to go for years to come. All without an excavation permit and no disruption to a very “historic” location.
