Salt Lake City, UT, June 30, 2006: Advanced Forming Technology (AFTEC) has unveiled their cost-effective Combo-Cast™ technology for StoneTree® Wall Systems. Used as sound barriers, highway walls, security walls, privacy fences and decorative perimeter fences, StoneTree® Wall Systems are constructed by precasting concrete with steel reinforcement. Included in the StoneTree® Wall System is a proprietary rigid footing design consisting of a pier footing with an embedded structural support which extends above the footing to half of the height of the fence. This footing structure eliminates the need for rebar cages which are typically required with more labor-intensive grouted cell designs. Additionally, AFTEC’s footing design ensures the safest and most stable installation of precast walls.
FeaturesThe Combo-Cast™ column and panel is precast as a single unit, eliminating over 50% of associated labor and equipment costs. Furthermore, the AFTEC Proprietary Forming Process (patent pending) provides efficient vertical casting for multiple Combo-Cast™ sections (six are produced in one form equating to ninety lineal feet) with identical textured design on both sides, further reducing the labor, costs and working space required.
These steel-reinforced precast concrete walls are more durable than natural stone, block and brick and do not require a continuous footing. The standard Combo-Cast™ section yields 15-feet from center of column to the center of column with a connection joint at the column which also doubles as an expansion joint to prevent problems associated with settling from sub-standard and expansive soil conditions that occurs with conventional masonry stone, block and brick walls.
