A PT pole can last a long time when embedded in concrete, with estimates ranging from 5 to 75 years. To maximize the longevity of the pole, it is important to apply a trowel around the pole so that water runs off and does not come into contact with the ground. Placing deck poles in concrete is not recommended, as it can lead to rotting at the bottom of the poles. Pressure-treated poles are more resistant to rotting, but moisture can still seep through the gravel and away from the bottom of the pole.
Treated 4x4 posts are ideal for many uses, such as building a fence, and can last for many years. In general, you can expect your treated 4x4 publication to last 20 years, but they can last longer depending on several factors such as pressure treatment or weather conditions. Concrete fence posts do not require after-sales treatment and require minimal maintenance over their 25-year lifespan. The concrete on top should be tilted from the pole to ground level to prevent water from accumulating around the base.
To ensure that your treated 4x4 pole lasts as long as possible, it is important to add exactly the amount of clean water indicated on the back of the packaging per bag of Concrete Mix and mix well. After digging the pole pit, 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. If completed correctly, several simple practices can extend the life of any pressure-treated wood embedded in concrete. The use of an anchoring system to join the poles of the wooden deck with the concrete is a more suitable solution for the longevity of the timber.
If you are thinking that adding a gravel base, making sure the wood is directly on the gravel with concrete around and tilting the surface are tedious additions in a vain attempt to avoid the inevitable, you are not alone. Submit your peer-reviewed studies to demonstrate that concrete in contact with wood treated with proper pressure preservative causes premature wood decay. And many to suit different sizes of wood, and these solutions are some of the best options to install between wood and concrete. Again, when laying the pipe, the best is a layer of gravel and be sure to reduce the concrete from the tops of the posts. Placing a thick layer of loose gravel at the bottom of the pole hole will allow groundwater to drip through the rocks and down away from the base of the pole. First, it is important to place posts on top of a coarse gravel bed 3 to 6 inches deep so that the base of the pole is in contact with the gravel.
This will ensure that any moisture that gets between the concrete and bottom of pole will seep through gravel and away from bottom of pole. With these simple steps, you can maximize your treated 4x4 pole's lifespan.
