How We Determined Moisture Levels
The test to be carried out is the Relative Humidity In-situ Probe Test in accordance with ASTM F2710 and recommended by AS 1884-2012. The concrete subfloor shall be considered sufficiently dry for installation of resilient floor coverings when measurements taken do not exceed 75% RH.
Number of test locations
Three test points for the first 100m2 and 1 test point for every 100m2. Total Test Points TP for 3,156m2 = 38 Test points. The appropriate depth for probe holes of the suspended slab is 20% of slab thickness – 40mm We Allowed 72 hours to achieve moisture equilibrium within the hole.
