New CL:AIRE Technical Bulletin TB16: Complete Continuous Monitoring in Underfloor Voids

This useful guidance has been written by the teams at EPG ltd and AmbiSense Ltd, and provides a robust and practical solution for the monitoring of under-floor voids.  This method of post-construction monitoring is not routinely required, however, it can be used on sites where incorrect membranes have been installed, or omitted all together, or where specified verification has not been completed. In addition, the method can also be used for assessing larger sites, so that the ground-gas risk assessment can be further refined to potentially remove the need for membranes across the whole site.
