Downhole & Crosshole<\/p>\n\n\n\n

    \n
  • Obtain Vs and Vp values of rock and soils at a point surrounding a borehole<\/li>\n\n\n\n
  • Multiple boreholes (up to 4) can be cross measured to create a 2D or 3D profile<\/li>\n\n\n\n
  • Used in areas where surface access is restricted<\/li>\n\n\n\n
  • Produce elastic modulus tables of shear, young’s, bulk and poissons ratio<\/li>\n\n\n\n
  • Very deep studies are possible, up to 300 meters<\/li>\n\n\n\n
  • High resolution crosshole profiles between two boreholes detect extents of voids or other hidden features<\/li>\n<\/ul>\n<\/div>\n\n\n\n
