How to fix fence posts

Our preferred method of Fixing fence posts in our experience is NOT to use met spikes as they often spin as they are driven into the ground. If they hit a stone or rock they tend to twist. Our preferred method is to dig a hole and use post crete to fix the post securely in place. Post crete goes hard within 10 – 15 minutes and gives you a straight sturdy post.
There are some occasions when concreting is not an option, for example when the neighbours patio is right on the boundary. It might not even be a fence post you wish to secure maybe a Gazebo or Pergola needs posts near paving or boundaries. In these circumstances you could use spikes which are simply driven into the ground with a sledge hammer but it is really advisable to put a driving block into the fence post spike first. This allows you to hit the spike as firmly as you like without bending the sides of the post holder.
On a concrete surface that you do not wish to break up, we suggest you bolt it down using Rawl bolts which are placed into holes drilled into the concrete and then tightened. As the head of the bolt is tightened the bottom sheath expands, gripping the concrete.
