4 Different Methods to Cure Damaged Pipes
Pipe issues are a very common problem that a homeowner will encounter in his home for numerous times in all throughout the year. When any of the pipes at home cracks or gain holes, this can be a nightmare in the making for the homeowner. Even the tiniest crack and whole can create a bigger and messier problem when left untended. Traditionally, the only way to fix this problem is through replacing the damaged pipe entirely. The process, however, is destructive to everything around the property because the contractor will have to dig up the entire length of the pipe. This method is not only destructive, it will also take up much time and in some households, downtime in plumbing function especially with the water supply can be quite an inconvenience and is the last thing the residents need. Lucky for us, trenchless pipe repair and replacement is now an option. Here are 4 different yet effective ways to fix damaged without the hassle and heavy financial burden of the traditional method:
- Pipe Bursting
Pipe bursting is a method used for pipes that are really in need of replacement. Some pipe can fare well with just being relined since in the earlier stages of damage, they still maintained their structure and shape. Others, on the other hand, are not so lucky. When a pipe is beyond saving, contractors opt for pipe bursting method to fix the lines. The main equipment for this method is a Pipe Bursting Tool. After the excavation process, the “bursting head” is fed through the pipe. At the tip of the device, blades are placed to cut open or “burst” the pipe as it is being pulled to the opposite opening. At the end of the tool, the replacement pipe is also attached so that the bursting and replacing of the pipe is done simultaneously.
- Internal Pipe Coating
This process is slightly short of pipe relining. Only, in this process, the cracks and holes in the pipe are sealed while the other parts of the pipe that are not damaged are left alone. A mixture of thick epoxy lining is sprayed over the interior of the pipe. This seal is guaranteed to last for generations without the danger of falling off.
This process is done by first, digging an entrance and exit point for the liner on both ends of the damaged pipe. After which, cleaning up the host pipe is done using a water jetting device. The next process usually involves a CCTV pipe camera to monitor the interior of the pipe and the extent of the damage that the pipe had obtained. After assessing the damage, the contractor then proceeds to mix the epoxy compounds with other liquid materials needed in order to make the liner. The epoxy mixture is then poured into the liner and the liner is flattened to evenly distribute the mixture. For the final process, the liner is then fed through the pipe with the bladed at the centre. The bladder in inflated and then the liner is cured to place.
This process is very much similar to the previous one, the only difference is that, where that process involved a bladder, this one utilises an inversion chamber. The liner is inverted to that the epoxy liner is facing the wall of the pipe for better adhering. In the curing process, a UV light device is used. This device is usually being dragged across the pipe by a remote-controlled robot.
