What is Our Trenchless Re-Lining “CIPP”?

Drain Re-Lining is a brilliant new form of a No-Dig Repair Technology with cost-effective and no-mess alternative to traditional drain repairs. Drain Re-Lining is proven and established method of placing a new pipe within an existing damaged pipe without excavation and with minimal disruption. Your drains are back to perfect working condition in no time, and will remain free flowing for years to come.

Drain Re-lining is a specialized form of sleeve similar to glass reinforced plastic. It is strong and high quality. The sleeve (new pipe) is measured to the length of the damaged pipe or drain run and cut to size. The sleeves are only 3mm in thickness and will create no flow loss. On measurements the team engineers will mix together special resin containing an activating catalyst to impregnated into the sleeve (new pipe) prior to installation. On installation to the damaged pipe work they will then insert special inversion pipe from air pressure machine or water method machine to create the new pipe to push tightly to the damaged existing pipe work and create a new pipe installation. The existing pipe line now has a new pipe line inserted in which is tough, strong and sealed to the wall surface. This will now make a better smooth flow along the pipe lines with no obstructions or defects. Please contact us for advice on Drain Re-Liners.

We are certified approved vendor by various cities in state of Texas “Health and human services department”.

How much does this cost?

Our pricing is competitive across the board, and because each lining project is bespoke, decided by the condition and type of pipe in question along with a number of other factors, we can make sure that the final total is cost effective for your business and allocated budget.

The benefits

  • Safe for drinkable water and environment (NSF 14 & 61 Approved)
  • No costly excavation of surfaces
  • Minimum disruption and down time
  • Suitable for diameter ranges 3” to 50”

  • All types of pipe material can be considered for renovation
  • Lining systems available for runs containing diameter changes
  • Runs of up to 2000 feet relined in one continuous length
  • Increased flow rates
  • Prevents tree root infestation
  • Lifetime warranty included dependent upon type of lining
  • Seals all open joints and cracks preventing leaks

The drain relining method

A flexible liner impregnated with resin is pushed through the drain, whilst an air bag is also pushed through to mold the resin to the pipe. The liner is heated, and once cooled will mold exactly to the sides of the original pipe. Once the air bag is removed, it leaves behind a smooth new pipe inside the original.

PIPE HEAL have recently introduced environmentally friendly re-lining system for working on sensitive projects and in the majority of situations would use material which is the only attract to international high standards.

The drain relining process

Drain relining takes place following an initial CCTV camera survey that will have revealed a damaged area. PIPE HEAL provide a full CCTV camera survey service for a number of scenarios:

  • A problem with the drainage might be obvious or suspected
  • As part of the routine with an ongoing commercial maintenance contract
  • To provide a survey to show the condition of the drainage system of a building or complex for potential new rental or purchase customers.

Once a problem has been identified the damage can be repaired by patching or relining the damaged areas. Drain relining provides a completely new lining within the drain without the need for costly excavation. PIPE HEAL provide two types of relining – hot cure and ambient cure depending on the situation.

  1. 1. The drain relining process begins with the pipework being high pressure water jetted to clean out any debris, silt, tree roots etc. The camera is sent through again to mark the exact locations of any pipes that adjoin the main pipe that will need lateral cutting once the liner has been placed and cured.
  2. 2. Following the jetting and camera work, the liner is measured to the correct length and marked with any relevant access points. Different types of liner are used for different jobs and some are much more flexible and able to maneuver around bends with ease. The liner consists of an inner felt layer with a reinforced plastic outer coating.
  3. 3. A resin is poured into the liner and forced through the entire length via a mangle system. The impregnated liner is then inserted into and through the damaged pipe. Once the liner is in place it is inflated via the air bag to take on the shape of the existing pipe. The liner is then left to cure.
  4. 4. Curing time varies according to temperature but ambient curing normally takes approx. 1 hour to harden.
  5. 5. The air bag is then deflated and pulled back through the pipe, leaving a completely new pipe in place.
  6. 5. The camera is run through again to check that there are no problems and the marked areas are laterally cut remotely – operated by PIPE HEAL’s state-of-the-art CCTV. A copy of the video can be supplied if required.


High Pressure Jetting

We lower a jetting lance into the blocked pipe and begin a high pressure jetting procedure. When the jetting lance reaches the blockage it will blast through the obstruction. As the picture shows the jets which face rearwards help flush the debris away so the drain will operate correctly again.


If the blockage should recur, we would send one of our CCTV drain survey teams to inspect the run of the pipe because if a previous high pressure jetting operation failed to rectify the problem it would indicate that the drain pipe has collapsed and is in need of immediate repair.
