Sometimes the quick and dirty approach costs more
Settlement, subsidence, lateral creep and slope failure problems are not always amenable to simple analysis or recommendations based on empirical calculations. In many cases, the observational approach to these problems can provide a more practical evaluation and cost-effective solution. Site-specific monitoring over extended time periods can be the only valid approach for assessment of changing conditions and risk. This requires the use of geotechnical instrumentation and, in some cases, it is attractive to use remote automated monitoring.
"London Bridge is falling down, and there is a problem with my cable TV!"
Time Domain Reflectometry (TDR) is commonly known as "cable radar" and has been used primarily by the cable TV and communications industries to find problems in coaxial cable. This time tested technology has been adapted to monitor movement of foundations, roadways, and slopes as well as changes in groundwater conditions and soil moisture. Coaxial cables and probes are being used for remote automated surveillance of large volumes of soil or rock with a single instrument.

How can we help you?
Clients in the private sector, mining industry, and State DOT's and other public agencies have benefited from our experience in risk assessment for subsidence and slope stability, including design and installation of early warning systems for critical structures over abandoned mines or near unstable slopes.
