A birds eye view of our Alverson Limestone Quarry operation.

Alverson Limestone® is a blue-gray to tan colored dolomite limestone.  We quarry, cut, and sort this limestone to various grades for use in various applications.  Available as Random Irregular (Mosaic), Ashlar Strip, and Ashlar Block (Square/Rectangular) cuts for full-thickness architectural building construction, or as Adhered Thin Stone Veneer for those jobs without a footer or ledge.  Alverson Limestone is also available for many hardscape projects, such as Thin, Regular, and Heavy Wallstone, Irregular Flagstone for walkways or patios, and as Armour Rock, Boulders, and Castle Step Slabs for those larger landscape projects.  This material in most cases is available either Bulk or Palletized to suit your needs.
