The bursting head is where the new pipe made of polyethylene will be attached. The cable is then pulled with the help of a hydraulic system. Once the cable is pulled, the bursting head attached to it together with the new pipe will also be pulled inside the old pipe line. Once the bursting head reaches the old pipe, it will fracture the material and push it out into the soil leaving a vacant area for the new pipe to occupy. The whole cable is pulled until the new pipe reached the other end of the sewer line where the connection is located. Once the puling is done, inspection of the connections as well as the pipe is performed before filling the holes.
One of the most common concerns of homeowners is the cost of the trenchless sewer pipe repair method. According to contractors, the cost is determined by the location as well as the hardscape. Hardscape is anything directly above the pipe line which is to be replaced. Estimate shows that for every foot, it might cost $100 to $200. Though it cannot be stated that this is much cheaper compared to the traditional method, majority of the cases shows this to be true. With the traditional method, the cost is mostly affected because there are structures affected and needs to be dug up and landscapes have to be restored after the repair. With trenchless, this is unnecessary since only a tiny portion needs to be dug for the entry holes.
Another advantage when using the trenchless replacement method is that it takes only a day or two and everything is done. With this short time, the household will be able to go back to normal after the replacement is over in two short days. The replacement pipe that is used to replace the old one is more durable and will last longer since it resists corrosion. It is also flexible and leak proof to avoid any leakage problem.
For homeowners who are planning to have their sewage line replaced or if their pipeline is experiencing leakage problems then the trenchless sewer repair method is more convenient. There will be no special equipment required for digging and no structures above the pipeline will be destroyed. Digging is only limited to two access holes required for the entry and exit point of the cable. After the replacement is done, it can be easily covered and landscapes will not be affected as well.
