Slip Lining Repairs Pipes With Little to No Excavation

You noticed you had a high water bills, so you called in a plumber to find the leak you knew you had. But, now you have to figure out what to do. What’s the best course of action for you to take? The one that will be the least destructive?

You have two options in front of you: Dig up your yard to get to the problem area, or have Boyd Plumbing leak detection experts come out and repair the problem without the excavation. What do you choose?

The answer is obvious – choice number two, right?

If so, you probably chose it for the mere fact that it will save you loads of money down the line repairing the damage that would have been done to your foundation or yard. But, you probably want some more information than just that.

The non-invasive – or trenchless – method we use for pipe repair is called slip lining.  Slip lining has been used since the 1940s and has proven time and time again to be an effective pipe rehabilitation technique.

Slip lining involves installing a smaller “carrier pipe” into a larger “host pipe.” This grouts the annular space between the two pipes and seals the ends. It stops infiltration and leaks, while also restoring structural integrity to an existing pipe.

There are two methods used to install a slip line – continuous and segmental.

Different Slip Lining Methods

  1. When a long, continuous pipe – like high density polyethylene (HDPE) – is pulled through the existing host pipe starting at an insertion point and continuing to a receiving point, that’s continuous slip lining.
  2. Though very similar to continuous, segmental slip lining is different because of the pipe material used as the new carrier pipe. When using a bell and spigot pipe, like an FRP or PVC, the individual pieces of the pipe are lowered into place, squashed together, and pushed along the existing pipe corridor.

 

At Boyd Plumbing, we will determine the best course of action for the specific problem you are having, and choose the repair method that we believe would be the most effective.
