Fixing new fence posts

With the winter we inevitably get gale force winds, recently of course heavy snow which combined often means that already weakened fencing fall down and needs to be replaced. If ypu have firm ground which is clay based sinking new posts into the ground is often all that is required, but sandy or loam based soils means that new posts will work loose. The first thing to stress when replacing fencing posts is that they should be fully treated against wood rot and the best method is undoubtedly pressure treatment, otherwise you are wasting your money as they will soon be subject to decay.

The rule of thumb for a fence which is six feet in height, the posts should be eight feet in height and two feet of this will be set into the ground, a four foot fence will have six foot posts and again two feet in the ground, anything less and there will not be enough strength to hold up an interwoven or close boarded fence. Ideally new fence posts should be set in concrete which provides a very solid foundation and will help to make your fence and other garden structures more durable. Concrete will give your structure a much firmer footing than using post spikes would, particularly if working with light soil or areas of high wind, but bear in mind that using concrete will add a couple of days to the overall completion time of the project whilst is sets.

When setting the new post in the prepared holes it is as well to have a helper to hold the post in position whilst you put the concrete mix in which is simply coarse sand and cement mix, which you should tamp down and leave. The moisture in the ground will be sufficient to set the concrete. Most good DIY or builders merchants will sell “post mix” ready prepared.
