The materials are formed concrete and steel reinforcing.

The price differential varies depending upon the type of stone or brick wall you are comparing it to. A totally natural stone wall would cost approximately five times the cost of the StoneTree® Wall System. Manufactured stone (i. e. Cultured Stone®, Eldorado Stone, Harristone™) and brick would cost more than three times the cost of the StoneTree® Wall System. A StoneTree® decorative concrete block wall would be comperable in cost to a block wall, but install faster. The main savings is in the labor, which is substantially less with our systems than other walls in the marketplace.

The solid steel reinforced precast concrete fence manufactured from AFTEC’s forming systems are much more durable than natural stone and brick mainly because there are no mortar joints, therefore eliminating the mortar bonding problems common with stone and brick. StoneTree® Precast Concrete Walls have an expansion joint designed every 15 lineal feet preventing expansive soil and settling problems that normally occur with conventional masonry stone and brick walls.

It averages out to approximately 65 lbs. per square foot.

The standard precast concrete forms are manufactured in banks of six column/panel units that total 90 lineal feet (27 lineal meters) of fence wall per casting.

An eight foot (2.4 meters) forming system requires approximately 12 cubic yards (9 cubic meters) of concrete, while the six-foot ( 1.8 meters) system uses approximately 9 cubic yards, (6 cubic meters) of concrete.

Each six foot (1.8 meter) high column/panel unit is 15’ 4” (4.64 meters) in length and weighs approximately 6,000 lbs (2700 kg). Each eight foot (2.4 meter) high column/panel unit is 15′ 4″ (4.64 meters) in length and weighs approximately 8,000 lbs(3600 kg).

Yes. The casting may be performed onsite on larger projects, which saves transportation, handling costs and increases efficiency.

The StoneTree® Wall Systems have been designed to meet many different site conditions from standard designs withstanding 90 mph winds to hurricane conditions of 150 mph. The walls are also designed for local seismic forces and soil conditions.

The AFTEC wall system includes the proprietary rigid footing support system, consisting of a rigid structural support embedded in the footing and protruding up half of the height of the wall, eliminating the need for steel reinforcing cages in the footings which are required with engineered designs of rebar connecting the columns to the footings (grouted cell design). The rigid support system is the safest and most stable method of installing a precast fence, eliminating the risk of panels tipping over while the footing cures. During installation, the Combo-Cast™ column panel unit safely encompasses the rigid structural support eliminating grouting and temporary bracing.
