Geoterra

Building Materials

The laboratory is well equipped to perform tests for a large variety of building materials, e.g., concrete, lime, masonry mortars, masonry clay units, and dimension stones. The laboratory also executes research programs and assessments of historical and/or damaged buildings according to Building Code Seismic Testing Requirements.
