Pipe lining for slab leaks
Slab Leak Pipe Lining Services in Texas
Last reviewed
Lining seals a pipe from the inside, so the floor stays closed. It works for some lines and not for others, and a technician has to check yours before recommending it. Call and we’ll connect you with a local Texas crew for slab leak pipe lining.
A technician can check whether lining suits your pipe.
What pipe lining is
Pipe lining, also called epoxy lining or pipe coating, is a way of repairing a water line without removing it. A liner material is applied to the inside of the existing pipe and left to harden, forming a new surface that seals pinholes and small cracks.
Because the work is done through the pipe’s open ends or a small access point, the concrete above the line may not need to be opened. That is the main reason people ask about it. It is not an option for every line or every leak, and a technician should confirm that yours qualifies.
How lining is carried out
- The line is assessed. The technician checks the pipe’s material, diameter, length, bends and condition, usually with a camera or by testing.
- The leak is located. Detection identifies which line is leaking, and how far the lining would need to extend.
- The pipe is cleaned. Scale, deposits and debris are cleared from the inside of the pipe so the liner can bond.
- The liner is applied. Depending on the system, resin is pulled or pushed through the line and cured in place, or applied as a coating.
- The line is cured and tested. Once hardened, the line is flushed and pressure tested before it goes back in service.
Water is off for part of the job. How long depends on the number of lines, the product used and the curing time.
Describe the line and the leak.
What makes a line a candidate
- The material. Lining is most often discussed for copper. Some other materials may not be suitable.
- The condition. Small pinholes and thinning are what lining addresses best. A pipe with a large break, a collapsed section or heavy damage is not a candidate.
- The layout. Tight bends, many fittings and long runs complicate the process. Fittings that leak at the joint may not be fixed by lining the pipe.
- Access. The technician needs entry points at both ends, which means openings in walls or at fixtures.
- The diameter. Very small or very large lines may not fit the product.

What lining does not do
- It does not fix every leak. A leak at a fitting, a break in the pipe or a failed joint may need another approach.
- It does not make an old system new. If other parts of the line are failing, lining one section does not address them.
- It narrows the pipe slightly. The coating takes up space inside the pipe, which is usually acceptable, but a technician should check the line’s flow.
- It is not a substitute for detection. The leak still has to be located first.
Ask what the technician is relying on to say the line will hold, and what the contractor’s workmanship guarantee covers.
Lining products and what to ask about them
Several lining products are on the market, and they differ in how they bond to the pipe and what conditions they suit. Ask the contractor which product they use and ask for the manufacturer’s information in writing.
Also ask whether the product has been used on the type of pipe you have, and what the manufacturer says about installation and limits. A contractor who works with lining regularly can answer these questions directly.
Pipe lining in Texas homes
Copper lines under slabs are common in Texas homes built from the 1960s through the 1980s. In areas with hard water, such as much of Central and West Texas, scale builds up inside older copper and can interfere with how a liner bonds, so cleaning is an important step. In Dallas-Fort Worth, expansive clay moves the slab and pipes against each other, and a line that has been bent or stressed may not suit lining.
Lining often comes up in the same conversation as rerouting and repiping. A technician who offers all three can tell you which one fits.
Questions worth asking before you agree to lining
- Is my pipe material and condition suitable for lining?
- How do you know the line is suitable? Will you inspect it first?
- What product is used, and can I see the manufacturer’s information?
- How long will water be off, and how long before the line is back in use?
- Which walls or fixtures need to be opened to reach the line?
- What does the workmanship guarantee cover, and for how long?
- What happens if the lining does not hold?
Describe the signs you have seen.
What preparation involves
Lining depends on the inside of the pipe being clean and dry. Before any coating or liner goes in, the line is usually drained and dried, then cleaned to remove scale and corrosion. Methods vary between systems, and the technician should explain which one they use.
Preparation also means confirming the line is a candidate. A camera or other inspection may be used to check for collapsed sections, heavy damage or sharp bends that would make lining unreliable. If parts of the line cannot be lined, those may need to be repaired or bypassed separately.
Water will be off for at least part of the work, and sometimes for longer than with other repairs because of curing time. Ask how long water will be unavailable, which fixtures will be affected, and when the line can be used normally again. Ask too what testing is done after curing to confirm the line holds pressure.
What to keep after lining
After lining, keep a record of the product used, the lines that were lined, the date of the work and any test results. If you sell the house, buyers may ask about it, and any future plumber will want to know which lines have a liner before cutting into them.
Ask the installer whether the product has any limits on future work, such as heat from soldering nearby, and note those in the same record.
Store the record where the next owner of the house will be able to find it.
Pipe lining questions
Often, yes. Lining is done from access points at the ends of the line, so the concrete above it may not need to be opened. A technician has to confirm the line is suitable.
No. Material, condition, layout and diameter all matter. Pipes with a large break, a failed fitting or heavy damage are usually not candidates.
It depends on the product, the pipe and the water. Ask the contractor for the manufacturer’s information and what the workmanship guarantee covers, rather than relying on a general figure.
Ask which product is used, whether it has been used on your type of pipe, and for the manufacturer’s information in writing.
The coating takes up a small amount of space inside the pipe. In most cases flow is acceptable, but ask the technician to check pressure and flow afterward.
Lining the pipe does not fix a leaking joint. If the leak is at a fitting, a different repair may be needed.
It varies with the number of lines and the curing time. Ask for a schedule before work starts.
Not always. The approach depends on the line, access and product. Ask for lining and the alternatives to be explained together so you can compare what each involves.
Ask the contractor. Some lined sections can be repaired or cut into, and others are more difficult. It is worth understanding before you agree.
