Frequently asked questions |
Q. What materials are the StoneTree™ fence walls made of? |
| The materials are formed concrete and steel reinforcing. |
Q. How does the cost compare to stone or brick wall? |
| 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 decorative concrete block wall would cost more than two times. The main savings is in the labor, which is substantially less with our systems than other walls in the marketplace. |
Q. How durable is this material compared to natural stone or brick? |
| The solid steel reinforced precast concrete fence manufactured with our 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 Fence 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. |
Q. How much does the product weigh per square foot? |
| It averages out to approximately 60 lbs. per square foot. |
Q. How many lineal feet does the standard AFTEC Forming System produce per casting? |
| The standard precast concrete forms are manufactured in banks of six column/panel units that total 90 lineal feet of fence wall per casting. |
Q. How much concrete does the system require for each pour? |
| The form that produces the six-foot high walls requires approximately 8.5 cubic yards of concrete per casting. |
Q. What is the weight and dimensions of the Combo-Cast units? |
| Each six foot high column/panel unit is 15’ 4” in length and weighs approximately 5,600 lbs. |
Q. Are the AFTEC Combo-Cast column panel units ever cast on site? |
| Yes. The casting may be performed onsite on larger projects, which saves transportation, handling costs and increases efficiency. |
Q. What type of wind specifications are the AFTEC wall systems engineered to? |
| The wall systems have the capability of being engineered and designed
to meet most any local requirement specified. At the present time in Salt Lake City, UT the fence walls have been designed to withstand 90 mph winds and the local seismic codes. |
Q. Why is AFTEC’s rigid footing support system superior to traditional footings engineered with steel reinforcing? |
| The AFTEC fence 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 fence 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 wall, 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. |
