Oahu & Maui Pipe Coating Services

Did your last plumbing inspection detect minor breaks in your pipeline? Consider pipe coating. Read on to learn more about this service. To schedule a visit from our experts, call 808-599-5511 or 808-877-6370.

Pipe coating is a fast, safe, and eco-friendly method of restoring your drain and sewer lines. A rotating brush is inserted into the line to coat the interior of your pipeline with a unique resin. When hardened, this resin produces a “pipe within a pipe” so you can continue using your existing plumbing line and avoid time-consuming replacements.

Allens Plumbing is the leader in trenchless technology. We offer pipe coating, pipelining, and pipe bursting services that restore your plumbing lines without having to destroy your property. Our Maui and Oahu pipe coating services help homeowners improve their plumbing and water efficiency. Here is what you can expect when you schedule this service.

What is Pipe Coating?

To better understand pipe coating, let’s start by defining slip lining or Cured in Place Pipe (CIPP). Slip lining is a sewer rehabilitation method where a factory-made pipe with a smaller diameter is installed into an existing host pipe. The new pipe is made of a felt-like material that is soaked or impregnated with a 2-part resin/epoxy mixture.

Pipe coating is also a method of sewer rehabilitation that provides similar results without impregnating the felt material. It’s still a calculated 2-part resin/epoxy mixture that’s applied to the existing pipe. The result is a semi-thick liquid that can completely coat the inside diameters of plumbing pipes, including around straight runs and around elbows and bends. This explains why epoxy resin is an extremely versatile and effective coating.

Since epoxy is a thick, viscous liquid, it coats, repairs and seals as it moves through your pipes. After the epoxy is mixed, it’s then blown through water pipes with filtered and pressurized air. As it’s blown, it fills small cracks and leaks. It’s also thick enough not to splatter inside your pipes. Instead, it tends to roll over itself, forming a uniform later inside the diameter of your pipes before it’s cured and hardens.

We apply both methods based on the competitive advantage that they can provide towards the logistics of each job. The logistical items may include:

  • Diameter size of the pipe
  • Access to sewer line
  • The sewer line’s degradation factor (how far gone is the pipe)
  • Length of the sewer line
  • Amount of tie-ins that exist (reinstatement factor)

An Overview of Pipe Coating

Before any coating is applied, we will video inspect your drain or sewer line to view the extent of the damage and determine if pipe coating is the right solution. We will then thoroughly clean out your pipe to remove any blockages or obstructions.

Then the coating begins. We coat lined or unlined pipes of various materials: cast iron, PVC, concrete, or clay pipes are all able to be coated.

The length of pipe we coat can just be a small area or your entire pipe system. We are able to coat pipes 32 feet at a time. Most pipes receive 1-3 coats of resin, depending on your specific goals (see below).

Highest Standards for Our Pipe Coating

When considering which materials we will use to coat your pipes, we use the most stringent standards and testing methods in the industry. We follow a highly detailed process prescribed by the American Society for Testing and Materials (ASTM) to determine which materials we will use to coat your pipes.

We test and consider the following:

  • Is the material used chemical resistant?
  • How much strain can be put on this material before it falls apart?
  • How much “give” is there in the material before it fails?
  • How much force is needed to strip off the material from the bond?
  • How thick should the material be applied?

Practical Solutions

Pipe coating allows you to either extend the life of your existing pipe, or create a totally new structural pipe. How much coating we apply depends on your particular goal.

Do you want to…

  • Extend the life of your existing pipe: We apply a single coat or dual coat of the resin (about 0.5-1mm inch thick). This provides your pipe with a newly slick interior for improved water flow and decreased risk of blockages.
  • Create new pipe within old pipe: This requires several coats of resin that will form 2-4mm of thickness (exact measurements depend on the size of your drain). This newly structured pipeline will serve you well for 30-50 years.

How Long Does it Take?

The pipe coating process is quick and you will not be without service for more than one day.

You can start using your plumbing again after 12-24 hours. The resin usually dries within 3-12 hours, and is completely hardened in seven days.

Will it Last?

The new pipe created from the hardened resin is extremely durable and can last up to 50 years.

Sewer and drain lines that undergo pipe coating become much stronger:

  • Damp-proof
  • Corrosion-resistant
  • Wear-resistant
  • Withstands shocks and bending
  • Elastic
  • Antistatic
