Things To Look For When Hiring A Culvert Rehabilitation Company
Culvert rehabilitation can be defined as the process of extending the service life of a given culvert without removal of the existing culvert.
There are three phases that are involved when rehabilitating a culvert. The the first phase of the culvert rehabilitation involves stabilization of the culvert. In this first phase you cut out curled-in pieces of the old culvert by hand, then you assemble the liner plates inside the culvert, section by section which are later bolted together manually.
Culvert rehabilitation’s second phase is known as the creation of a smooth lining. During the second phase of culvert rehabilitation, a smooth, watertight and sound pipe which is structurally sound within the new tunnel liner plates is created Smoothening of the corrugations made by flanges is also done.
Soil stabilization phase is the name given to the third stage of culvert rehabilitation. Soil stabilization involves addressing the cause of the dramatic failure, in other words, the extremely unstable soil surrounding the pipe; to prevent similar problems for the rehabilitated culvert, stabilization of the surrounding soil with cementitious grout, which is injected until refusal.
To ensure the quality of the done culvert rehabilitation, normal inspection procedures should be applied.
The history of a given company is the number one priority to consider before hiring one. one should carefully follow the past contacts the company has made with its customers, whether it sticks to the terms and conditions of the agreements made. A rehabilitation company with good history can be trusted to rehabilitate other culverts.
One should consider the kind of material used by the culvert rehabilitation company.
To avoid incidences of the rehabilitated culvert from malfunctioning of breaking down again, a company that uses proper and materials that are of the high standard should be considered.
An important factor to consider during making a choice of what rehabilitation company to give the job is the overall cost involved. A company that offers to rehabilitate the culverts at a cheaper cost but maintaining the high quality and standard of the culverts should be given priority as the cost of rehabilitating a culvert should not be similar to that of purchasing a new one.
Another measure to consider the kind of workmanship offered by the given rehabilitation company. A company with skilled workers will ensure high quality of rehabilitated culverts are produced hence increasing efficiency and minimizing the incidences where the rehabilitated culverts malfunction.
The period taken by the given culvert rehabilitation company to complete a given project should also be put to consideration.
If one desires to have the rehabilitated culverts for example in one month, a culvert rehabilitation company that can produce high quality the culverts within or less than a month should be given priority.
