If you have not worked in the excavation of a road or a highway, you probably not thought about the importance of a culvert. We need to know the importance of culverts in the infrastructure sphere. Terrible weather conditions can cause massive floods in just a short span of time. As floods come, there is a need to have a device such as culverts to control the water and floods.
A culvert really is any form of embankment used to let the water flow so that the area will not get flooded. 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. To protect a property, it is important to look at the benefits of having a culvert. Flooding may cause erosion and unexpected expenses. There are possibilities of damage on certain objects found on the road when exposed for a long time to flood waters.
The thing is that culverts may get ruined over time. There could be a need for culvert rehabilitation. Culvert rehabilitation is an emerging phenomemon given the fact about aging culverts in United States alone. There is an emerging 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.
There are several culvert rehabilitation methods used by top culvert maintenance companies.
The slip lining method entails rigid liner pipes being pushed or pulled with jacks. There is an object getting inserted to the existing pipes. To finish off, a space is getting grouted to create a seal.
Spiral wound lining means the creation of a smooth and continuous 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.
One way to rehabilitate the culverts is the use of the cured-in place liner. It generally involves inserting a flexible liner. The liner is usually coated with a thermosetting resin, which is then inserted to an existing pipe. 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.
There are a lot of companies out there that can help you with culvert rehabilitation.
