BluKote Lining

envirologics icon line  Line

Following Tomahawk cleaning, preparation and pipe evaluation, any lining technology can be applied to the pipe wall, including CIPP (cured-in-place pipe) or SIPP (sprayed-in-place pipe) technologies. However, the optimal lining technology choice depends on the condition of the pipe determined during pipe evaluation.

Envirologics now offers our proprietary airborne lining solution called BluKote. This application is a fast, low cost, non-structural, AWWA Class I barrier coat to improve water quality and flow while extending the pipe's service life by decades. The lining process uses the same airstream as cleaning (vac truck), thus requiring minimal changeover.  The airborne lining process is capable of lining 4"(100mm), 6"(150mm) and 8"(200mm) diameter pipes which represents approximately 75% distrubution pipes in North America. BluKote is NSF/ANSI 61 certified for contact with drinking water.

The lining application produces significant flow improvements due to C-factors > 110.  The service connection shown below is fully coated with no voids or shadows around the exterior.  Material does not fill or block the unobstructed service. The BluKote liner is continuous and fully bonded in this crucial location.  Pipe joints are fully coated and often filled for a countinuous liner, providing excellent results.
