Material Rippability

Material Rippability Predictions Derived From Seismic Refraction Survey

Refraction data were recorded along six profiles (300 feet long each) across a 5.6 acre, undeveloped parcel with bedrock exposed in several places.  Profiles were designed for 40 feet of penetration to see if sewer main installation would require blasting the granitic bedrock.  A bedrock depth contour map was generated as an AutoCAD layer and laid on the project development map.
