One of our clients contacted us recently. They live in a high wind area and were worried about the fence coming down in a winter storm.
Our experts have seen a lot happen over the years and have a few tips on damage limitation.
Among the list of tips on how deep you should go with the fence posts are:
- Go down at least one third of the length of the post
- Three feet is the minimum in high wind areas
- Avoid going too high with the fence
- Set the posts in concrete
- Use sturdy posts
Let’s take a closer look at each point.
Go down at least one third of the length of the post
This is good advice for any fencing project but an essential tip to follow for a high wind area.
Your fence post will be put under enormous pressure when the wind blows.
Gusts of wind can often come out of nowhere and do a lot of damage.
Dig a hole at least one third the length of the post, and bury it well to protect it during windy weather.
Three feet is the minimum in high wind areas
Don’t skimp on the length of your fence post.
You do not want to wake up after one of those stormy nights to see your new fence lying flat on the ground.
The fence post should go at least three feet into the ground, more is preferable, especially if you live in a high wind area.
If you live in a cold area, there may be guidelines to follow on going below the frost level too.
The deeper you go with the fence post holes, the more secure it will be when the high winds blow through your property.
Avoid going too high with the fence
A simple rule to follow, when building a fence in a high wind area.
Your fence panels can act like sails, gathering the full force of the wind during a storm.
If you reduce the amount of fence surface open to the wind, then you will reduce the pressure on the fence posts.
Reduce the height and try to make the structure as permeable to the wind as possible.
Set the posts in concrete
As well as putting the posts into the ground as deep as is possible, you need to secure them well too.
We recommend setting the posts in concrete, to give them extra durability when standing up to the high winds.
The concrete can also protect the posts from rot while in damp soil and stop termites from getting into the wooden fence posts.
If you plan to move the fence from time to time, then setting in concrete may be a problem.
Try using pea gravel to keep the posts in place, as it is easy to lift posts when the time comes for moving.
Use sturdy posts
We’ve had a few clients who take on board our tips but go for the wrong type of posts.
As you will be burying the posts deep into the soil, you should only use pressure-treated wood.
The wood must also be appropriately treated for burial, to prevent rot and termite infestation.
We recommend using Fence Armor around the foot of the posts for extra protection.
Fence posts should be a minimum of 4 x 4 in high wind areas, to give the strength needed during a storm.
