Applied Felts parent company, W.E. Rawson Group, was formed in the United Kingdom in 1865, manufacturing quality textiles for a number of applications. After more than a century of experience, this knowledge was expanded to help create the CIPP process, as well as its first liners. Now, more than 30 years later, Applied Felts has become the international leader in supplying top quality liners for successful CIPP installations around the world.

In 1997 Applied Felts expanded its business to the United States by adding a manufacturing plant in Martinsville, Virginia. This move opened up a whole new world of opportunity in what has become the world's largest market for CIPP rehabilitation. To date, Applied Felts has more than 50 million metres of successful underground installations around the world.

Applied Felts is a 100 per cent vertically integrated liner manufacturer, which guarantees that every phase of manufacturing — from the purchase of raw fibre to the coating and manufacture of liners — is done in one location, providing impeccable precision and control over the quality of the products.

These innovative liners are subjected to a rigorous 28-stage testing system during every phase of the manufacturing process:

• First, raw materials such as polyester fibres, polyurethane granules are inspected and tested to ensure a superior quality basis for each felt liner manufactured.
• Next, a number of criteria are tested including density, thickness, fibre distribution evenness, strength and weld-ability of the finished felt.
• The third step is the coating of the felt. Applied Felts utilises a ‘single pass’ extruded process to ensure that no pinholes are present. During this phase, four separate tests are conducted to monitor coating uniformity, mass and weight distribution.
• Once the felt has been coated, each roll is sampled and destructively tested across a total of nine quality characteristics, including density at various pressures, tensile strength, coating distribution and more. During production, the testing doesn't end. The liners are continually checked to ensure they satisfy the specifications of each customer’s unique order.
• Finally, when the project is complete, a sample is cut from each finished liner and is tested across yet another seven criteria to make sure the circumference, density, length, coating integrity, weld strengths and other properties meet and exceed requirements.

The finest quality CIPP liners are just the beginning of the story. Applied Felts is also a complete solution provider, standing behind and supporting their customers every step of the way. Each relining job is different, and almost always provides challenges and unique situations that require experience to get the job done right.
