There aren't many household systems more confusing than plumbing, which is why I stopped trying to fix mine on my own. I realized that taking things apart was increasingly more difficult, so I stopped guessing and started looking for a trained expert who could come out and help. When I found the right professional, it was amazing to see how much easier things were. They went through, evaluated my plumbing system, and made changes that changed my home from the inside-out. Check out this blog to find out more about how to avoid plumbing problems and when to hire a professional of your own.
You finally got your driveway replaced and sealed and now you find out that your sewer line, which lies beneath the aforementioned shiny new driveway, needs to be replaced. Visions of a backhoe digging a trench through your driveway to replace your sewer line are almost too much to bear.
Fortunately, you have options to the backhoe and the trench. Trenchless sewer line replacement is available that requires very little digging. There are different options available, depending on the condition of your old sewer line.
Option 1: if your old sewer line is cracked and broken, but still relatively intact
This option creates a liner that fits inside your old sewer line, sealing it and helping to maintain its integrity. A special type of epoxy is sprayed along the inner walls of the old sewer line, and before it is allowed to harden into its final shape, a bladder is inserted along the inside of the sewer line.
The bladder is then inflated to hold the epoxy against the inner walls of the sewer line. This allows the inner liner to form along the walls of the sewer line as it cures and hardens.
This liner is not as susceptible to invasion by tree roots as your old cast iron sewer line, and isn't easily cracked by shifting earth or extreme temperatures. This method requires only one hole to be dug on your property.
Option 2: If your old sewer line is beyond redemption and needs to be removed and replaced
This type of trenchless sewer line repair requires the use of brute force. A conical shaped wedge is pulled through your old sewer line by a cable line powered by a hydraulic generator.
The shape of the wedge, with the small end in the front, allows it to follow along the length of the sewer line. The wider back end is the business end, and breaks the old sewer line apart as it travels along the line.
When the old line is shattered into pieces, a new sewer line is then pulled through the existing passage with the same hydraulic powered cable line.
This method requires two holes to be dug, one at each end of the sewer line.
Although these methods can be more expensive than the traditional backhoe and trench, you also need to consider the cost of replacing what is lost at ground level, such as your shiny new seal coated driveway.
