Our pipes will always malfunction and can be severely damaged due to factors such as improper use of the pipe system and environmental factors as well. This kind of issue should be repaired immediately in order not to cause further damage to the entire system. There are several pipe rehabilitation methods used in order to mend and bring back the condition of your pipe system. On the other hand, if you think that these methods involve in heavy excavation process, don’t worry for these methods are improvised in order not to put disruption into your property. Here are the following:

Internal pipe coating

Internal pipe coating is actually similar to pipe relining method. On the other hand, the distinction is that the holes and the crack inside the pipes are sealed while the other parts of the pipes that aren’t damaged aren’t included and left alone during the internal pipe coating process. Using a thick epoxy lining, the interior portion of the pipe is sprayed with it. The advantage of this method is that its seal is very durable that it could last for several generations without even falling off.

Pipe bursting

Pipe bursting is a pipe repair method that is suitable for pipes that are immensely damaged and the only option to do is to replace them without creating trenches similar to the traditional method. Although there are some pipe issues that can be mended through relining them at the same time keeping the structure and the shape of the pipe, pipe bursting is used when the pipe can no longer be redeemed. The main tool used during this operation is the bursting tool. Prior to the operation, there should be two holes that serves an entrance and exit of the tool. After that, the tool is then inserted within. At the tip of the tool is a blade that bursts and cuts open the severely damaged pipe. On the other hand, on the end portion of the tool is that replacement pipe. Thus, bursting and replacing process is done at the same time.

Cured-in-place

This method is similar to the pulled-in-place method. However, the difference is that the pulled- in-place method uses a bladder. In cured-in-place method, the liner is reversed to the epoxy liner that is actually facing the wall of the pipe in order to adhere properly. Furthermore, in the curing process of the liner, this method uses a UV light device. Throughout the process, the tool is being dragged across the pipe by a robot that can be controlled with the use of a remote.

Pulled-in-place

The initial process of this method involves in digging two holes for the entrance and exit point intended for the liner. The next thing to do is to free the pipe from obstructions through the use of a mechanical tool known as hydro jetter. Subsequent to the cleaning operation, a CCTV camera will be inserted into the pipe to see if the obstructions are already gone. Also, this is used to determine the condition and other problems like leaks, holes and cracks. After that, the contractors will then mix liquid materials and epoxy compound needed to make a liner. Then, the epoxy mixture is then poured into the liner and is distributed evenly by flattening it. The last step involves in installing the liner into the pipe along with the bladder at the centre. While the liner is cured into place, the bladder is then inflated.
