Interstitial (UST 23-C & UST 23-D)

A method of leak detection where the area between the inner and outer walls of a double wall tank or piping is checked for the presence of liquid or a vacuum to determine if there is a leak.

PS&C technicians test interstitial space of your tanks or lines in accordance with the manufacturer’s regulations/recommendations and in accordance with the PEI/RP100.

Our technicians ensure that the interstitial space of your tank is tested using a 3rd party certified interstice tightness test capable of detecting a leak from the inner or outer wall of the interstice for the tank model that is installed.
