Problems that arise within a city’s infrastructure can be very costly, especially when considering full depth operations. Nortex specializes in innovative repairs to address leaks, voids and deterioration of large diameter pipes, culverts and other associated structures including manholes and drop inlets. We have the knowledge and experience to fix these issues, avoiding costly repairs and providing a time efficient solution.
CORRUGATED DRAINAGE PIPES
Due to the nature of issues associated within a city’s infrastructure, solutions almost always include excavation, proving to be quite costly and time consuming. However, the solution Nortex provides for these types of problems require no excavation at all. In addition to that, our solution avoids costly repairs and long periods of down-time.
The project below shows how high-density foam was used to support this large corrugated plastic drainage pipe from being crushed by the soils above it. This pipe was located under a bridge and was used as a conduit for the stream that flowed beneath it. In addition to strengthening the pipe from the overbearing weight, the foam provides excellent insulation from outside elements, and does not expand or contract under the fluctuation of hot and cold temperatures.
In the project below, it can be seen how polyurethane foam was injected in the annular space between the corrugated slip lining pipe and the culvert. There were a total of five adjacent pipes, in which three of them needed foam injection. The foam was injected throughout the length of the culvert.
