Description

Fold and Form (F&F) PVC Liners have been in use globally for over 30 years and have become a well-accepted rehabilitation method for sanitary and storm sewer collection systems, as well as road and rail network drainage culverts. They have proven to be more reliable and consistent from a QA/QC standpoint, due to the fact they are extruded in manufacturing plants according to rigorous ASTM standards (F1871/F1867 and F1504/F1947). This means that liner mechanical properties are known AHEAD of installation, and the finished liners are significantly less impacted by on-site conditions, variables and workmanship, as opposed to CIPP and other rehabilitation methods. Given the significant emphasis on Styrene mitigation in sewer rehabilitation, F&F PVC liners offer an environmentally friendly alternative to CIPP.  Since these liners do not contain styrene, there is no release of odors or flushing of chemicals of any kind during  installation. This makes this technology the preferred option for environmentally sensitive locations like roadway stormwater drainage, as well as densely populated urban sanitary sewer networks.    F&F PVC liners meet structural design requirements, and provide a minimum 50-year service life, corrosion resistance to hydrogen sulfide and other chemicals, abrasion resistance and low friction for improved hydraulic flow. Several case studies on current projects in the USA, Canada, Australia and other international locations will be discussed as part of the presentation.

After this session, attendees will be able to:

1. Explain to clients (private and public asset owners) the similarities and differences between F&F PVC lining and CIPP rehabilitation.   
2. Discuss the significant advantage that PVC liners offer for rehabilitation in terms of elimination of styrene exposure both airborne and in the runoff from installation.   
3. Provide rehabilitation crews performing the work with a safer and easier installation method and working environment, without exposure to dangerous chemicals or need for specialized PPE on site.   
4. Discuss how using a factory made PVC liner provides consistent, repeatable and successful results, while significantly mitigating financial and operational risks and consequences of failure.

Ideal Audience: Sewer rehabilitation contractors, including owners of the company all the way through crew members performing field installation.
