WITH MEASURABLE RESULTS
HydraTite® (Internal Joint Seal System)
A culvert in Watertown, CT had a significant water flow and erosion problem, leading to culvert joint separation, invert deterioration, erosion issues, and headwall damage. The erosion had undermined the outlet which resulted in a disruption in water flow. With the age of the culvert, the inlet headwall was made with stacked stone. Over time, these stone headwalls can settle and become weak, starting to lose structure. This culvert was located under a roadway which also had challenges with traffic control. The separating joints caused concerns because the above roadway could be damaged by infiltration.
HydraTech implemented an engineered solution to address all of these issues. HydraTite seals were installed over the culvert joints for a permanent solution to the leaking separated joints. Five tons of riprap (large diameter stone) were placed over the existing outlet void to prevent further deterioration and erosion by restoring natural water flow. The stone headwall was encased in two layers of concrete to prevent further structural damage and environmental erosion.
The job consisted of the installation of nine HydraTite seals that were 72” in diameter, placement of five tons of riprap, concrete patching inside the pipe, and the concrete casing of inlet stone headwall.
The HydraTite Solution enabled a trenchless repair at a fraction of the cost of fully lining the pipeline. The sealed joints and repaired invert restored the hydraulics and eliminated damage to the above roadway by preventing infiltration. All of this work was completed from the side of the road with minimal traffic disruption. The HydraTite seal proved to be an economical in situ repair solution.
