Here's a photo from the archives of the Olivenhain Dam inundation area circa 1998 prior to construction of the dam. ISE took this photo during some early field reconnaissance of the site to quantify some of the site constraints. This area is now currently under approximately 200-feet of water.

The blasting vibration data obtained from this site was instrumental in developing a new seismic surface wave prediction model - the R-Wave model.

Featured Video Clip (Concrete Fail)

ISE performing load testing of concrete test specimens to determine its axial compressive failure characteristics.

In this example, you can see quite dramatically how concrete fails under a compressive load. Once the ultimate stress is reached, the load carrying capacity of the material rapidly drops off producing the fracturing seen in the video.
