You can use soil and gravel instead of concrete when setting fence posts. However, concrete is more durable and longer lasting, so it's worth considering if you want your fence to withstand the test of time. You should especially consider concrete if you live in a region that experiences severe weather, which can damage your fence.

A barbed wire fence will last an average of 15 to 20 years, but the life expectancy can range anywhere between five and 50 years. Thicker wires last longer, as do fences made with galvanized metal. If the barbed wire fence is in a climate with harsh winters and summers, it likely won’t last more than 10 to 15 years. Failing to keep up with maintenance and repairs will also shorten the lifespan of a barbed wire fence.

You have several options for anchoring a temporary fence to keep it from falling down. Sandbags can be used as a standard weight, but they may blow away or fail in strong winds and inclement weather. Spikes and bolts are a cost-effective and easy-to-install alternative, but drilling can be difficult if the ground is frozen, too soft, or too hard. Another option is wind braces, which should be bolted into the ground to withstand turbulent wind; however, like spikes, they can be challenging to install in very soft or hard ground.

The thickness of a glass fence varies widely based on its application and whether or not there are any safety requirements, but most fences are between 8 millimeters and 12 millimeters thick. 12-millimeter-thick glass is extremely strong and overkill in most cases, which is why you typically only see it around pools and in skyscrapers.
