Different Types of Leak Repair

Published on:
December 22, 2021

Everyone who occupies a home is guaranteed to experience plumbing problems at a given time in their occupancy. When plumbing problems strike, they affect our daily lives, destroy our walls, ceilings, and lawns. In addition, we pay for the water we haven't used, making the question of how to repair a leaking water pipe evermore persistent.

It is essential to address plumbing challenges as soon as detected.

Remember, though, it's always crucial that you allow someone with the proper licensing and experience to repair your leak. Otherwise, you might make the leak worse than you started with.

Unfortunately, it can take weeks or even longer for the average homeowner to know they have a leak since many pipes and plumbing components are behind walls or floors.

What Are the Signs of a Leak?

Look out for these tell tales to tell if you have a leak.

Remember, you need to hire a professional for professional leak detection services to pinpoint the exact area and cause of a leak to have it repaired. But here are some indicators you can watch out for and listen for on your own.

  • The sounds of running or dripping water when no plumbing appliances are running
  • Soft spots on drywall or ceiling
  • Loss of Water Pressure
  • Unusually wet spots in landscaped areas
  • An area that is green surrounded by drier conditions
  • A sudden flow of rusty water or dirt or air in the water supply
  • A portion of an irrigated area turns brown when it used to be thriving
  • Heaving of pavements
  • Sinkholes
  • Leaning of structures
  • An unexplained sudden increase in water use

If you observe any of these tell tales at your property, there may be a leak. Therefore, it is wise to engage a professional to pinpoint its exact location and perform repairs.

Different types of leak repair

There are two major types of seals used in leak repair. They are elastomeric seals and composite wrap.

Elastomeric seal

An elastomeric seal comes from silicone elastomer-based material such as silicone rubber, silicone foam, silicone sponge, cellular urethane, and fluorosilicone. These silicone elastomers are synthetic rubber materials that provide a base for many seals.

Composite wrap

A composite wrap is a permanent, cost-effective pipe repair technology suitable for non-leaking defects such as external corrosions, dents, pits, and gouges. Composite wrap repairs an operating pipe without taking it out of service. As a result, it is quick and less costly.

A fundamental determinant of the type of repair component to be used is the state of the pipe surface. If damaged severely, a composite wrap is preferable over an elastomeric leak. Composite wrap products have extensive applications covering various defects, including gouges, dents, non-propagating cracks, and corrosion.

Techniques used in leak repair

Now that we understand the two different seal methods for leaks, These seals are applied using various techniques. These techniques include:

Metallic Patch

A metallic patch is a suitably curved patch 'fillet' welded to the pipe to repair minor non-leaking defects. Keen to note is that the thickness of the weld region must be sufficient. This type of repair is rare in high-integrity applications.

Pin-hole Leak Repair Clamp

Suppose it is a small pin-hole leak. It is advisable to use a pin-hole leak repair clamp. The pin-hole repair clamp uses a locator pin that guides a pointed cone seal into the leaking pin-hole. The cone seal is tightened in place by a forcing screw, and when the seal is compressed enough, remove the pin.

Simple Encircling Sleeves

Simple encircling sleeves are practical, especially in sectional areas of defective pipes. The sleeves are closely fit to the outside diameter of the pipe and welded together. In order to contain the pressure, the sleeves must be fully seal welded.

Stand-off Repair Clamp

Another name for Stand-off Repair Clamp is enclosures because they enclose the defective area within a sealed pressure containment vessel. Elastomeric seals usually do it at the joints of the two half-shells and seals.


If you have observed a soaking wall or ceiling and now wondering how to repair a leaking water pipe or your lawn has a green patch making you puzzled about how to fix a leaking water pipe underground, don't be perplexed anymore. Instead, engage a professional who can correctly diagnose your situation and use any of the above-explained methods and techniques to repair your leak.
