New Method of Investigation of Rising Damp in Brick Walls by means of Impedance Tomography

摘要

Abstarct:This paper presents a new nondestructive method of brick wall dampness testing in real building structures. The method is electrical impedance tomography EIT. It makes it possible to obtain a 3D distribution of wall dampness. Basic information about the built measuring system, including prototype equipment, is given. The setup was used to determine the dampness of test brick walls on a specially built laboratory test rig. The test results obtained by the nondestructive impedance tomography method are compared with the results obtained by the conventional destructive dryweight method.
