Methods of Curing the Resin Used In CIPP Lining

A leaking sewer might be the worst plumbing issue you have to deal with. Unfortunately, this problem is all too common, especially in places where sewer lines are close to plants whose roots grow into the sewer. The leaks also follow poor plumbing maintenance and excessive use of store-bought drain cleaners for drain unclogging, which destroy the inner parts of your sewer pipes.

The leading method of fixing sewer leaks used by Woodbridge-based plumbing experts before your pipes burst open and spew sewage all over your property is relining.  This technique is also called trenchless repair technology or CIPP (cured-in-place pipe) lining. A resin lining tube is inserted into your leaking sewer pipes using inversion or winching. Different methods are used to cure it once it is in place. The following are some of the curing methods used in CIPP lining.

Ambient Cure

This procedure is used for the curing of pipe linings with a small diameter within a short period. The process involves the use of a small portion of the lining resin to initiate a chemical reaction that starts the curing process when the lining comes into contact with your sewer.

Ambient CIPP curing is cost-efficient and leaves little trace of the repairs. In most cases, however, hot water is used to speed up the ambient curing process and enhances the durability of the lining resin. This curing process can not be used to cure thermosetting resins.

Hot Water Cure

The technique can be done on different types of thermosetting lining resins, including polyesters and vinyl ester epoxy systems. Repaired pipes cured with hot water are strong and have high structural integrity. However, this curing method is expensive.

Steam Cure

This closely resembles the hot water curing method but uses a gaseous rather than liquid water state for curing. Though expensive, the amount of wasted water is less than that in hot water cure. Steam curing is mainly preferred over hot water cure because it is eco-friendly. Its drawbacks and benefits remain the same as the other.

UV Cure

This is the most commonly used technique of curing CIPP lining. It is more cost-efficient to use UV curing rather than steam or hot water for huge pipes. The UV liner is first tugged into place then blown up. After this, a UV light source is pulled through the liner and adheres it to the pipe. Though it results in a durable repair, UV curing is costly.

CIPP lining has genuinely revolutionized the repair of leaking sewer lines and pipes. To guarantee that no other issues are contributing to the leak, plumbers today use drain inspection cameras. When the plumber is sure nothing is blocking your pipes which will cause future leaks, they can then start the process of trenchless repair.

This method is inexpensive, fast and has minimal soil and traffic disruption on your property. Once in place, the lining is cured using the above techniques, and your pipe is as good as new.
