Soil and Rock Laboratory Testing

Soil and rock samples can be obtained from the site subsurface by several means and some of those methods, as seen in the following in-situ services section, will give immediate results of the engineering properties of material being retrieved. The laboratory at MEA preserves and carefully stores samples collected in the field in order to get accurate representations of site conditions when tested.
