A method is provided for detecting and locating anomalies in soil subjacent to an existing structure. Electrodes are placed into the soil both outside the structure and through the structure's foundation. Electrical resistivity data is collected using these electrodes. This electrical resistivity data is analyzed to create an electrical resistivity map or model. Inspection of the map or model can allow the operator to detect and locate resistivity anomalies which may correspond to geological anomalies in the soil. In alternative embodiment, one or more soil samples are taken from the soil adjacent to the existing structure. Laboratory resistivity measurements are performed on the soil samples to provide a set of baseline resistivity data. A resistivity map or model is produced as described above. This resistivity map or model is compared to the baseline values provided by the laboratory resistivity measurements of the soil samples to detect and locate resistivity and geological anomalies. Moreover, comparison of the resistivity model with the actual soil sample resistivity baseline allows the operator to more accurately detect subsurface anomalies by minimizing the problem of non-uniqueness and allowing the operator to disregard outlying data.

Subsurface modeling method

Subsurface mapping apparatus and method

A pad to be disposed between a load and a sling. The pad has at least two woven Nylon bands or layers joined together by a yieldable, flexible adhesive. The warp threads of the bands are respectively angularly oriented.

Protective pads for overhead lifting

Pad devices disposed between a lift sling and a load and permitting relative sliding motion between the load and the sling without the load and sling being in direct engagement and thereby avoid and/or minimize damage to the sling and to the load.

Clutch pads

Pad devices disposed between a lift sling and a load. The pad permitting relative sliding motion between the load and the sling without the sling and the load being in direct contact. This avoids damage to the sling and/or the load during the lift.
