Are Post Spikes Or Concrete Posts Better For Fencing Post Support?

A fence post can be positioned with either a large spike or a post-mix. Both methods have their benefits, for long term benefits, we always opt for the post-mix.

A post-mix is stronger and lasts many more years when compared to a spike.

If you are erecting a fence for a short period then the fence spike will be the better option because it’s easy to remove.

Fence Spike Post Support

The fence spike is a large red spike you hammer it into position with a woodblock, insert the fence post and screw together.

This method is good for novices but does not stand up to the test of time.

Once you add wind and rain the spike will become loose and your fence panel will start to move.

Over the years we have replaced thousands of spiked fences for concrete fixings. All of these fences were only erected a year or two before we replaced their fixings.

Fence spikes really are a very temporary solution and should never be used for a long-standing fence.

  • Easily hammered into clay or soil
  • Will only last a year before they move
  • Good for temporary fencing
  • More expensive than using a post-mix

Fence Post Mix Support

A fence post-mix is a serious fixing and will generally outlast the fence post.

You dig a deep hole about 2 feet, making sure the lower half is rounded (football size) for a sturdier fixing.

A Post mix is made of shingles, cement and sand. You can purchase a single bag of post-mix that will be enough for ONE fence post.

But you can easily make your own with builders sand, cement and shingle.

  • Long term use to fix fence posts
  • 2 feet deep lower half should be wider
  • Cement, sand and shingles
  • Much stronger than spikes
  • Cheaper than fence spikes


For general building and landscaping purposes, the post-mix is far better for gardens.

This is because once the post-mix sets it’s there for many many years to come.
