1. Pipe Bursting
The pipe bursting method is usually advised for old or rotten sewer pipes or pipes that are in a very bad condition. From the word ‘bursting’ itself, the old or rotten pipes are replaced by bursting them. The pipe bursting method is done by making small openings at each end of the pipe that is to be replaced. After the openings are done, a thick cable is inserted through the two openings of the pipe and a bursting head tool is then attached. After securing the bursting head,a new pipe is attached to the other end. In the process of pulling the bursting head tool through the pipe, it ‘blows up’ the old or rotten pipe while completely replacing it with a new one simultaneously.
2. CIPP Lining
This is the Cured-In-Place-Pipe method of sewer pipe repairs. This can be done even if the pipes are somewhat still in a good condition but are in dire demand for some added strength.This process is quick and efficient in replacing sections of pipes that have fairly damaged parts.This method is usually done by installing a new liner into the manhole or any other access point of the pipelines that are to be replaced. In most cases, there is no need of excavation for this method as long as the existing pipe is not more than 60”. The new liner then is sealed in place with a hot and high steam pressure through the use of a bladder.
This pipe relining method is for laying down new pipes. From the name of the method “moling”itself, a special machine called a mole is pneumatically-driven through the soil. After the mole has emerged on the other side, the new pipe can now then be pulled through the hole that the mole had created. This process is commonly used for water pipes and the heating coils of heat pump system.
This method is used for pipelines that are partially gapped or cracked. A fiberglass and a resin liner are used to line the existing damaged pipe. In this process, two holes are dug at each end of the area that needs mending. Then, using a wench, the new liner is pulled into place and is cured through an ambient temperature or what we call as steam.
This method is used for sealing pipes that are still in a good condition but have slight cracks and gaps. The process of inversion lining is to dig a small hole near the area where the inversion liner should be placed. The liner is mainly made out of a felt tube and a resin which makes it strong and durable.
