The Process of Installing Formadrain Fibreglass Liners

Before any fiberglass liner can be installed, it goes through a careful preparation process. First, the fiberglass layers are coated with epoxy, also known as “wetting out” the fiberglass. This ensures that each fiber is thoroughly saturated for maximum durability.

Next, the fiberglass is wrapped around a rubber mandrel, which is used to provide structure and form. To protect the material from external elements, it’s wrapped in polyethylene. The liner is then U-folded and taped securely to keep everything tightly in place. This step ensures the liner stays intact during transport and doesn’t get damaged along the way.

Finally, the prepared fiberglass is rolled onto a spool, ready to be sent to the job site for installation. With everything prepped, the installation process can begin with confidence.

 One of the greatest advantages of fiberglass liner installation is that it requires absolutely no digging! This approach is fast, clean, and efficient, saving both time and money.

The installation process is straightforward. The liner can be pushed into place through a single access point or pulled into place between two access points, such as manholes or cleanouts. The preferred method is typically the pulled-in-place option because it allows for more control during installation. With two lifelines for adjustments, installers can ensure the liner is correctly positioned.

Additionally, the pulled-in-place method allows the liner to smoothly navigate around tricky pipeline features such as Ts, Ys, and bends up to 90 degrees. No matter how complex the pipeline system may be, fiberglass liners can easily adapt and transition to any size, ensuring a perfect fit every time.

After the liner is in place, it’s time for the curing process. This is where steam curing comes in. A steam line is connected to the mandrel, and steam pressure is applied for a specific period.

The result? A fiberglass liner that’s not only incredibly durable but also uniform and wrinkle-free. The steam curing process ensures that the finished product has a smooth and consistent finish, providing a strong and reliable solution for your pipeline needs.
