Abstract
The first part of this chapter describes laboratory verification tests for determining the efficiency of various consolidation treatments on stone. It compares material data acquired using circular discs and rectangular plates. The application of rectangular plates enables the testing of not only strength but also of other material characteristics (e.g. moisture, water saturation or temperature dilation parameters on identical specimens). Therefore, it may be very useful for the testing of consolidation agents being developed before their introduction into conservation practice. The second part introduces a portable ultrasonic double-hole probe for measuring material properties along a depth profile and assessing penetration depth in the near-surface material layer between two drilled holes. This moderately destructive method is useful mainly for measurements on stone masonry façades or structures in which drilling a hole is acceptable.
