Precast Fence Walls
Written by GJ Stott
Precast fence wall usually refers to concrete walls that are first cast with cement forming and then installed later. These precast concrete walls have been around for several decades and have seen several revisions and changes to become what is used today. Original concrete walls were simply precast concrete columns, spaced four to eight feet apart with wire or paneling strung between each column.
A Brief History on Precast Wall
Technological advancements made 20 to 30 years ago started to change the way precast wall was manufactured. The first precast walls were cast while lying horizontally on the ground. As innovations were made, smaller precast wall systems could be cast vertically and have texture on both sides unlike one-sided finished products from horizontal systems.
Precast wall manufacturing improved once again when vertical casting techniques were used on larger concrete forming machines . Advanced Forming Technologies (AFTEC) introduced a gang way to make this possible, and liners are now used in form systems to ensure quality texture on both sides of the wall and column.
AFTEC has also developed, through the use of their proprietary Combo-Cast™ process, concrete forming machine equipment that incorporates the casting of both the column and the wall panel together, cutting associated costs in half by lowering the amount of labor needed in the transportation and installations of the precast concrete walls.
Benefits of StoneTree® Precast Wall Systems
Due to the integration of column and panel, the StoneTree® precast wall section does not require bracing during installation. Again, using innovation and emerging technologies, StoneTree® precast wall employs the AFTEC-patented Rigid Support System for footing construction of its fence.
A concrete footing is constructed fifteen feet on-center into which a rigid support in the form of a four inch “I” beam is installed. Once the footings in the wall line are cured, the precast wall panel and column unit is lifted and set into place and does not require any additional labor or adjustments. The wall can be constructed as quickly as the panel and column units can be lifted into place.
Another advantage of the StoneTree® Precast Wall Forming Systems is that they are designed so that the texture form panel liners are easily interchangeable; thus, they provide precast wall manufacturers the ability to produce a variety of double-sided finishes in the supplied precast wall including stone wall, brick wall, slate, rock, and architectural designs.
