We have a problem of walls getting wet, probably from a leaking pipe somewhere behind the walls and cannot locate the source. Local plumbers (in Guwahati, Assam) are trying all sorts of trial and error methods and breaking up several parts of the walls. Are there any suitable modern techniques to detect such leaks through the wall / structural units? Contact information of suitable equipped companies from Guwahati would be welcome.
