The feasibility of using electromagnetic waves in determining the moisture content of building fabrics and the cause of the water ingress

In this paper, the feasibility of using electromagnetic (EM) waves is determining the moisture content of building fabrics and the case of water ingress in experimentally assessed. This paper will concentrate on investigating the propagation of EM waves through typical structures and their interaction with concealed pipework, wiring and timber. All current methods are overviewed and analysed. Novel microwave sensor described in this paper operates in 6 GHz to 12 GHz frequency range using Marconi 6200A microwave test set. Results of experimental test confirm that microwaves can be used as an alternative nondestructive method for identifying different object behind the walls.
