Will the concrete rot the poles

Simply placing the poles in concrete creates a condition that will accelerate rotting at the bottom of the poles. With pressure-treated poles, rotting will be slow. We have three ways to solve the problem of rotten poles. Concrete should be poured around the pole, with no concrete under the pole.

The concrete on top should be tilted from the pole to ground level to prevent water from accumulating around the base. The most common fault with concrete poles is neck rot, where the pole rots right at the point where it comes out of concrete at the ground line. This can be easily avoided if the concrete is slightly above ground level and is domed or tapered away from the pole so that water does not fall into the wood. Drainage is the key, keep standing water away from the poles and they will last much longer.

This is a horrible idea in my opinion. Check out The Fence Bible at your local library. Cement doesn't rot your posts, moisture does. If you don't allow concrete to absorb moisture into the surrounding dirt, it will rot your poles quickly.

Finally, fill the entire hole with cement to the top. Concrete will hold the fence firmly in place and prevent any lateral movement. For even more protection, dome the top of the concrete so that it tilts away from the pole to divert water from the pole. The post will only rot at ground level, no matter what you put in the bottom of the hole.

A pressure-treated pole will last about 10 years. If you use metposts, the post will still rot, they will only make it easier to replace %26 in my opinion, they look awful. Pressure-treated wood will rot in concrete when exposed to damp conditions, such as trapped water. Under optimal conditions, pressure-treated wood placed in the ground can last up to 40 years.

However, when placed vertically on a drainless concrete base, pressure-treated wood can last only a few years. I had heard that plastic wrap would prevent lime from concrete from eating into the wood over time. Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will cause wood to break concrete. That's why when you pull out an old fence post, the rot only goes a couple of inches below the level or where the pole exists the concrete, the bottom of the pole is solid.

While concrete is tough, it lacks the drainage of gravel and can trap moisture, which ultimately leads to rotting. And for added protection, dome the concrete top so that it leans away from the fence post to divert water from the fence post. Step every 15 cm and you will get it as solid as concrete and this would keep your poles as dry as possible. Submit your peer-reviewed studies to demonstrate that concrete in contact with wood treated with proper pressure preservative causes premature wood decay.

There are several different products on the market, which claim to work well for joining wood to concrete. If a proper coarse gravel bed installation is completed as in step 1, the wood that sits on top of the gravel will be able to drain moisture accumulated in the concrete due to the coarse gravel layer underneath. To overcome the problem of ground level rot, I tamped the concrete mix at ground level to provide a foundation on which to lay one or two rows of bricks around the base of the poles, hoping that this will prevent the action of soil rotting, even if the poles are treated. I have another question, I haven't concreted up to ground level, about 5 inches from ground level.

Ideally, dig the cellar deeper and place gravel under the pole to allow water to drain more easily, and then fill the rest of the well with concrete. Pressure treatment of wood is a sure way to improve the longevity of wood and prevent it from rotting. After digging the pole pit, for example, or forming foundations, make sure that before pouring or placing any concrete or wood in its place, a coarse gravel base of at least several inches is placed on the bottom of the pit or formed area. .
