GeoStone is a patented modular wall system that is based on the open core concept. This means no lips, pins, lugs, or any other such appendages are required for connection giving the installer complete freedom of installation and design. The GeoStone retaining wall system is based on two different sized blocks (1 sq ft unit and 1/2 sq ft unit) that can accomplish most applications the industry's wall systems require including radii, steps, corners, tiers, and even true ashlar. The GeoStone retaining wall product is marketed on a national level through dealer/distributor networks and block/specialty concrete manufacturers. On a more local level GeoStone has a complete Hardscape sales and design division that focuses on not only the GeoStone retaining wall system but complementary items such as pavers, travertine, outdoor fireplaces / kitchens, columns, and other outdoor living components. GeoStone's design capabilities range from simple planning to photo realistic renderings, 3D walkthroughs, and geolocation through satellite imagery. We use high definition cameras to capture images and textures when creating our products in our virtual library. This way our virtual designs will look real enough to reach out touch.
