Clamp wooden posts - different methods


Wooden posts can be attached in many different ways. Each method has its own advantages and disadvantages. Whichever type you prefer depends on the purpose of the wooden post. In addition, the wooden post must be simultaneously protected from moisture from the ground. We show you here the individual types of attachment.

Turn in or screw in

The common ground sleeves are either hammered or screwed. The cheapest option is certainly the impact sleeves for posts. In many areas, these sleeves are also the best choice. However, on very light, sandy soils these impact shells will soon begin to wobble.

For these floors, screw-in sleeves are the better choice. Through the twisted thread, the sleeves sit a little tighter in a loose bottom. In a very solid ground you will often not be able to turn the screwed-in sleeves far enough. When driving in the simple ground sleeves, you should be careful not to hit the metal itself. You need a short post, which you can reuse for all ground sleeves as impact wood.

Concreting gives grip

For a carport or a patio roof, for example, a wrench or screw-in sleeve for the posts is often not sufficient. You then need a sleeve or a concrete anchor, which are firmly connected to a concrete foundation. For light buildings or sturdy fences, often a point foundation is sufficient, into which you embed a ground anchor.

Concrete foundation available

There is now a large selection of beam shoes and screw sleeves that can be screwed onto an existing concrete foundation. These give the post much support and at the same time protect it from the moisture of the soil.

Protection against moisture

No matter which type of attachment you choose, you should always make sure that there is still about one centimeter of air under the post in the bracket. Most post mounts already have a mandrel there that prevents the post from slipping off the factory.

Tips & Tricks

In the past, posts for fences, for example, were generally hammered directly into the ground. But since there are many practical fasteners today that better protect the wood from moisture, this method is hardly used anymore. For a high quality fence you should therefore prefer this variant.
