Drain & Pipe Lining

Cured-in-place pipe lining completely restores broken or failing drain and sewer pipes without having to dig up the ground or have direct access to the pipe.

Drain Lining Services

We’ve had the opportunity to install over 25,000 ft of liner in the GTA area, needless to say we are extremely experienced in this area and even manufacture some of the materials ourselves. If you are considering replacing your drain or sewer pipe we strongly recommend you contact us to discuss the benefits of our drain lining services.

Drain Lining Process

We’ve broken the process down here into eight illustrative steps showcasing the process from start to finish:


Step 1. Camera Inspection


The closed circuit television camera permits to identify all visual defects
inside the designated pipe (blockage, collapsing, water infiltration, etc…),
also, it is used after rehabilitation process.


Step 2. Snaking


Snaking is the most effective method of pipe cleaning and it allows to
remove debris and/or tree roots from the sewer system.


Step 3. Insertion of a bladder into felt tube


The tube consist of a layer of laminated, flexible, needled felt capable of
caring resin, withstanding installation pressure. The bladder is made from
reinforced PVC membrane and can bear pressure up to 30 PSI.


Step 4. Preparation of epoxy composition


Appropriate amount of resin and hardener are measured according to the
length of the liner and carefully mixed to form a homogenous substance.


Step 5. Saturation of a fibrous tube with epoxy


The pre-measured amount of resin is introduced into the liners front end and a
vacuum is drawn from the opposite end. The vacuum and rolls are assisting
the resin penetration into the liner fabric.


Step 6. Insertion of a liner into the old pipe.


The liner/bladder assembly is inserted into the old pipe through the access
point – a small excavation or a clean-out. The pushing rods inside the
assembly are capable of delivering a liner up to 30 feet long.


Step 7. Inflating the tube with air.

The liner is typically held in place at 10-12 PSI for 3-4 hours and cured at
ambient temperatures. Once the liner has cured, the air pressure is reduced
and the inflation bladder is reverted away from the cured pipe by pulling back.


Step 8. Cutting the liner to get a new pipe.


To conform the quality of the installed liner second camera inspection is
performed and the new pipe is connected to the existing sewer system.
