 MCleak™ is a testing method developed by Leak Detection Technologies (LDT) for the leak testing of fluid filled interstices associated with double wall containments. The interstitial space in double walled tanks or containments is filled with a liquid monitoring solution. A level measurement is made using a special tool designed by LDT. The liquid measurements are recorded and entered in an algorithmic calculator also developed by LDT that calculates the test duration, wait period before measurements, and calculates the leak rate from the measurements collected. 

  

MCleak™ was primarily developed for testing the integrity of newly installed double walled fiberglass tanks and requires a 72 hour wait period for fluid stabilization before the testing process can begin. The testing period is significantly reduced when measurements are obtained from inside the 4-inch interstitial riser pipe rather than inside the interstitial fluid reservoir. Tanks that are already in service must be taken out of service for at least 72 hours prior to beginning the test

  

MCleak™ is primarily used in California but is expanding by acceptance from the fueling industry across the US. The fueling industry is adopting the test process as integrity and commissioning test at new construction sites.


  

MCleak™ is listed by the National Work Group of Leak Detection Evaluations (NWGLDE) and was evaluated by Ken Wilcox Associates according to EPA protocols.
