Abstract:Exterior water can penetrate a building and move in either continuous or discontinuous flow. In the case of continuous flow, from point of entry to point of observation, surfaces of construction materials are wetted and may provide a path of adequate conductivity to produce a detectable alternating electric field when a voltage is applied. Where this is the case, a suitable a-c ource and detector can be used to determine the source of water entry.
For cases where water flow is discontinuous, det… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
