Fence Post Spikes Vs Concrete

I never build a fence deck or any other structure unless the sono s go down a little over 4 and a decent psi concrete is poured.

Fence post spikes vs concrete.

I won t even pour concrete walkways without a sono every five feet and then we run 1 2 rebar up and through the whole walkway. Metal spikes are available in different sizes suitable for different heights of fence. Concrete in fence post holders are designed for use where soil conditions are unsuitable for drive in spikes. Wooden posts do not weigh as much as concrete posts so they are not as difficult to install.

A sledgehammer is required to drive the spike into position. The main reason for this is because the posts were all level. A 750mm 30 inch spike is suitable to support a fence which is 1 8m 6 feet high. Simpson strong tie offers a line of products designed to help make reinforcing fence posts easy and economical.

Don t forget to check it is level before allowing the concrete to go off. The average concrete fence post weighs circa 40kg. Typically a concrete post for a 1 8m high fence is twice the safe weight for one person to lift. According to my husband who actually built the fence it was easier to build the fence on the concrete post side than it was on the spike side.

Since fence post spikes are topped with a box that secures the base of the fence post just above the ground you instantly cut the odds of having rot problems. A 600mm 24 inch spike is enough for posts which will support fences up to 1 2m 4 feet high. Another consideration is frost heaving. The main con is that since its designed to be driven down the tapered tip will offer less torque even set in concrete than a post set to a similar depth.

I plan to fit a new fence on my front garden. Good spikes hold wooden fence post bases securely with strong bolt in systems providing sturdy wind resistant fencing that won t sag or lean. The bare adapter should not heave but the combined concrete adapter might unless the pour goes below the frost line. I don t yet have either a post hole digger or some gravel and post fix for digging.

Given the cost of these items still yet to be sourced i wondered if it would be easier cheaper to use metal spikes for the posts instead. Haven t touched my fence for about 12 years since we did concrete posts plus concrete panel about 30cm high to keep the woodern panel off the ground. I have read the two previous posts and agree with them in normal circumstances.
