Methodology
The liner is shipped in special containers and UV protected foil and can be stored
for up to 6 months without refrigeration. Sewage flow needs to be either plugged
or by-passed. After sewer is cleaned and CCTV inspected, the Blue-Tek liner is
winched into the existing pipe, inflated with air (6 to 8 psi) and then cured using a
UV light train that is pulled through the pipe. Special care is needed to ensure
that the exterior film is not damaged during installation. After curing the inner
film is removed and discarded and the liner post CCTV inspected.
QA/QC • Verification of UV lamp intensity and number (wattage)
• CCTV inspection of entire line before curing
• Record of liners inner air pressure during curing
• Documentation of curing speed (feet/min)
• Resin reaction temperatures (infrared sensors)
• CCTV documentation of curing process
• Physical property tests on specimens from the liner, including watertightness
porosity test
