Municipal governments and other infrastructure owners are increasingly taking an interest in understanding rehabilitation methods to prevent groundwater infiltration and corrosion in wastewater structures. SpectraShield has participated in three independent studies for the evaluation of effectiveness in resisting infiltration and corrosion.

In 1996 SpectraShield participated in the CIGMAT program at the University of Houston. The objective of the study was to evaluate SpectraShield for adhesion, resistance to external hydrostatic pressure, and chemical resistance. SpectraShield passed in all three categories.

In 2013 SpectraShield was evaluated by the U.S. Army Corps of Engineers at Fort Bragg, North Carolina.  The Corps released their report and findings in April 2016 and rated SpectraShield with a return on investment (ROI) of 5.5.

In 2017 SpectraShield was evaluated by The Geo Engineering Centre at Queen’s University, Kingston, Canada for resistance to external water pressure.  The test was conducted to over 120 feet of hydrostatic pressure and the SpectraShield Liner remained intact.
