Vibrocoring is an effective and flexible technique that allows the collection of long and undisturbed cores in water saturated sediments.
When the required length of cores is not more than 5-6 m, in shallow or deep water, in lakes, rivers, beaches and any water saturated soil, Vibrocoring is simpler, faster and more economical than traditional drilling techniques. In cases of Environmental Impact studies, it is the recommended technique for sampling.
