YeDoma has brought new technologies to our local market.  We have two dynamic probing rigs.  The super heavy weight hammer has the same energy as the standard penetration test and a solid cone tip is more resilient to consecutive blows of the hammer.  YeDoma has been using the equipment over the last three years for anomaly detection, compaction control, and site characterization and subgrade sampling (continuous sampler and using our auger head).  Special sample tubes are added to collect relatively undisturbed samples. The dynamic probing increases reliability as each consecutive blow of the hammer is logged and hidden weak zones and layer boundaries are mapped to within inches of the actual contact.
