The Wildcat Dynamic Cone Penetrometer satisfies one of the basic needs in the field of consulting geotechnical engineering; the need for a quick, simple, portable, inexpensive means to determine the safe foundation bearing pressure for support of an ordinary magnitude load. The need might be initiated by planning for a modest addition to an existing structure; by a decision to build in a difficult access location; or simply by a backhoe operator's comment that the soil at this footing excavation location just doesn't feel right.
ISSMGE proposes an international reference test procedure for dynamic probing. Its equipment recommendations are shown in the table below.
