Trenchless Pipe Lining FAQs Answered

Pipe repair and replacement, until recently, has been a mostly costly and messy process. At Pipeshark, we provide trenchless pipe lining in Bryn Mawr, PA, a more efficient method of repair that requires no excavation. Since this process is fairly new, most of our customers have a lot of questions regarding this method. We answer some of the most common questions we get from homeowners below:

What Does Trenchless Mean?

Until about 15 years ago, sewer replacement meant a complete excavation of the areas to replace. This approach meant refilling soil after repairs and considerable disruption to the surrounding area. Trenchless repair or pipe lining, on the other hand, replaces old pipes with liners and requires a minimum of excavation at pipeline endpoints.

How Does Relining Happen?

Expert pipe lining companies, like Pipeshark, avoid extensive machinery and rely only on a small set-up and crew of about three or four people. With only a small access trench, they use a camera inspection to check the pipe’s interior for breaks, misalignments or blockages from corrosion, debris or water-hungry tree roots.

After a complete cleaning, the pipe lining crew blows in a flexible and resin-soaked liner that matches the pipe’s shape. This new cured-in-place-pipe, or CIPP, liner then hardens as an effective internal replacement to the existing line. The new line eliminates breaks, defends against tree roots and can last for about five decades.

A good application for trenchless pipe lining is cast iron pipes. While cast iron is a strong material that holds up to heavy loads, it can tend to be a case for corrosion and rusting. Cast iron pipe lining is a good way to prolong the life of an existing line by completely restoring its functionality.

What Are the Costs of Trenchless Repair Compared to Traditional Excavation?

The costs of CIPP pipe lining are actually about similar to the costs of standard excavation, and a single process for a longer single line will cost less per foot. However, the process overall still ends up saving you time and money.

While trenchless repair essentially leaves everything undisturbed, standard excavation involves associated matters that add up, like soil refilling time, yard seeding, tree replacements, transportation for excess soil and any replacements for patios, driveways or decks.

How Long Does Pipe Lining Take?

While there may be some preparation time needed before set-up and a follow-up visit by city inspectors, the actual work usually doesn’t take longer than one workday.
