The Top of the Fence The top of the fence in general should be delineated. This can be as simple as a 2” x 2” runner along the top of the form or can have an interesting pattern fastened to the forms as illustrated. As the fence is sprayed the concrete is shot up underneath this top finish board so there is a place to stop. The imagination can be free on how to finish the top. It could be made to look like a picket fence, it could be made to have a flat top, or it could be let run wild and have an organic look. Corners, Inclines, and more... This fence is marvelously versatile. The corners can be square, angled or rounded. On an incline the fence can come down in steps or can follow the slope of the hill. The fence easily spans ditches because of its strength. It is simple to vary the height of the fence for privacy or a favorite view. The top of the fence can have any desired finished shape. Likewise the fence itself is extremely versatile. On an incline it can come down in steps or follow the slope of the hill. 8
Step 2 Install Fence Posts The next step in building either of the fences is installing the fence posts. Measuring The Layout Pull a string along the property line to delineate it. Measure carefully the distances along the string and from the string for the proper zigzag or other pattern. The post should be poured up flush with the ground level or 1/2” to 2” above the ground level, then insert three vertical bars of #3 rebar. The fence post above is the thickness and depth for a zigzag fence. Fence posts poured in a zigzag pattern (below). Determine The Post Size And Distance The posts are obviously key to the fence standing up. The size must be large enough to restrain movement in the soil. If the fence posts are in line they must be larger than for the zigzag fence. The size of the post is best determined by the type of the soil. If the soil is sand and not prone to loosing while wet, a 6 inch fence post may be all that is needed. More than likely, the fence post should be 8 inches in diameter. If the soil is subject to flooding and not much strength when wet, the post may need to be built 12 inches in diameter. If the soil doesn’t have some good side to side holding characteristics then a straight fence is probably not the best to build. The zigzag fence may be used here, but may be even increased to 3 foot zigzag on 16 feet. The post hole is then of not much importance, a 6 inch or 8 inch post hole would be fine. The post for the straight fence should be eight feet apart and for the zigzag fence they can be twelve to sixteen feet apart. Installing The Post Care must be taken to fill the post 9
