Drainage issues can spell doom for property owners, disrupting routine activities and potentially causing extensive damage. Drain lining, also known as cured-in-place-pipe lining (CIPP), presents an efficient, non-destructive solution to such problems. This article will explore the different methods of drain lining, providing insights for homeowners and property managers seeking appropriate drainage solutions.
Typically, drain lining involves installing a new pipe inside an existing one, hence reducing the need for digging and invasion into the property. The leading methods of drain lining include the hot cure method, the ambient cure method, and the inversion method, each with distinct attributes and ideal application scenarios.
1. Hot Cure Method
Popularly used for large scale commercial projects, the hot cure method involves heating a resin-impregnated liner in order to cure or harden it into a new pipe. This process results in a robust and durable lining that can resist consistent use and harsh conditions. The liner is positioned into the pipe, then hot water or steam is introduced to activate and harden the resin.
This method offers drain lining the advantage of speed, with the curing process significantly faster compared to the ambient cure method – typically taking around two hours. However, hot cure installations require skilled technicians and specialised equipment, thus increasing installation costs.
2. Ambient Cure Method
The ambient cure method, also called the cold cure method, is the most common type of drain lining technique. It uses the same premise as the hot cure process, but relies on normal environmental temperature to cure the liner, making it an energy-efficient option.
The liner is usually saturated with epoxy resin and then pulled or pushed into place. Once correctly positioned, it’s left to cure, typically taking around three to four hours. The ambient cure method is cost-effective and ideal for small performance repairs, like residential pipe re-lining.
3. Inversion Method
The inversion method utilises air or water pressure to turn the liner inside out while pushing it into place. The pressure ensures the liner tightly fits onto the pipe walls, covering any defects. Afterwards, curing can be done either through ambient or hot curing techniques.
The inversion technique is highly efficient in covering long distances and navigating tight bends with less chance of the liner getting damaged. However, it requires detailed planning and precision during installation.
In conclusion, the choice of drain lining method will depend on several factors such as the size and condition of the pipes, the property’s requirements, budget constraints, and the urgency of the operation. All these drain lining methods have common objectives: to restore the structural integrity of the drainage system, improve flow efficiency, and prolong the life of the pipes. Investing in quality drain lining solutions saves long-term repair or replacement costs, hence offering excellent value for money.
