Southern Geophysical have added the equipment to undertake spectral Analysis of Surface Waves (SASW) . The Spectral Analysis of Surface Waves (SASW-S) system is designed for the following applications:

• Determination of crack depth and repair audit
• Determination of pavement system profiles including the surface layer, base and subgrade materials
• Determination of abutment depths of bridges
• Condition assessment of concrete liners in tunnels, slabs, and other structural concrete members
• Evaluation of alkali-silica, fire, fire, freeze-thaw and other cracking damage
• Velocity vs. strength correlation
