Keys to Understanding the Importance of Culvert Rehabilitation

For many people, culverts are non existent and probably may not be something that would sit in their minds. Culverts are a vital piece of infrastructure that helps control the flooding after a heavy rain or a storm. It is possible storms will bring lots of rain, in turn cause a lot of floods. Culverts are there to help control the water and flood.

A form of an embankment that controls the flow of water in a given area may be called a culvert. More often, the culverts being installed today are cylindrical with some reinforcements such as a pipe or with the use of concrete.

The culverts can also help in not just reducing water build up but also control erosion due to water damage. There is no doubt that a culvert is critical in the protection of a property. In most cases, too much flood waters may end up causing erosion and may lead to costly repairs. Not only the floods can compromise the integrity of the road, but also other objects that might get ruined due to the accumulation of water.

With constant use, culverts may need to be rehabilitated. There could be a need for culvert rehabilitation. Culvert rehabilitation is an emerging phenomemon given the fact about aging culverts in United States alone. As such, there is an increasing need to rehabilitate the culverts. There is a need to ensure the culverts’ structural integrity is maintained so it can function the way it should be.

Maintenance companies are using several culvert rehabilitation methods.

The slip lining method entails rigid liner pipes being pushed or pulled with jacks. They are then inserted with the use of machines into the existing pipes. As the liner has been placed, the space is grouted in order to create a seal which then helps rehabilitate the pipe.

Another way to rehabilitate the culvert is through the spiral wound lining with the use of a smooth and spirally wound liner. The method entails the use of a liner with interlocking strips, which is then inserted and coiled to an existing pipe. A spiral would pipe will be inserted and pressed until the liner sticks to the old pipe.

Another method is called cured-in place lining. It generally involves inserting a flexible liner. Through an existing pipe a liner with a thermosetting resin will be used to rehabilitate the culvert. The liner will be activated with the use of heat.

Another method using heat is called the fold-and-form lining with the help of PVC pipes.

On the other hand, cement-mortar is a method to use hot air to achieve a smooth finish against corrosion.

The internet is a good place to look for reliable companies that can help rehabilitate the culvert.
