R.W. Corkery & Co. has undertaken a range of programs to assess the quality and quantity of a wide range of construction materials and industrial minerals, e.g. sand, gravel, soil, hard rock aggregate, clay, brick clay/shale, sandstone, diatomite and building stone.  These programs incorporate geological mapping, review of drilling results, resource testing and presentation of reports.  Where appropriate, advice is given regarding quarry layouts and staging of extraction.
