LIMIT YOUR LIABILITY- Standards pertaining to moisture testing have become more stringent. AS/NZ 1884 (resilient flooring installation) was revised in June 2012. In a nutshell, the revisions state that it is necessary to determine Relative Humidity (RH) at depth, referencing ASTM F2170-11 as the preferred test method. Moisture Meter content figures are no longer relevant.
RH at-depth provides the best indication of what a flooring installation will experience at any time in the future. While it is a hedge against flooring failure- in the worst case scenario of a failure occurring for any reason, having completed a full, standards-compliant test prior to installation will limit your liability.
Example: A resilient flooring installation in a large medical premises- the installation was successful, until over six years into the floor's life, when the adhesive re-emulsified due to moisture vapour and the associated alkaline solutions. Not only did the flooring buckle, the emission and odour of re-emulsified adhesive created considerably adverse health conditions for all personnel. Quite obviously the slab had taken on moisture from a secondary source long after the installation. However, the flooring contractors were required to assist in remediation because they could not provide a compliant moisture test at the time of installation.
FLOOR TEST AUSTRALIA have provided RH% moisture testing services to major CBD/ suburban apartment developments, Government buildings, Tourism sites, Hospitals, Schools, Major Retail facilities and Aged Care sites. Projects include the following:
