PROCEIL WBS 3100 Test
For 5 years we subjected our PROCEIL WBS 3100 Weather Barrier System (WBS) to a 1 foot water column immersion cell test with UV exposure. After 5 full years under water with over 1 foot of head pressure, our PROCEIL 3100 WBS did not break down, or allow water to leak through the CMU test substrate. This was an extreme test for a weather barrier that should never have to perform under full immersion service with hydrostatic head pressure.
