Should I Concrete my deck posts?
Considering this, can I pour concrete around deck posts?
In weak soils you want to reduce the loading on the soil. A larger cross sectional area post will do that. Pouring concrete around the post, as long as the concrete is locked onto the post, will do the same.
Similarly, why deck posts should not be set in concrete? A deck post should always be placed on top of footing, not inside concrete because it can break. Concrete tends to absorb moisture and wood expands when it gets wet, so these two factors combined will result in the wood breaking the concrete.
Simply so, should I use 4x4 or 6x6 deck posts?
A short 4x4 can carry an awfully big load, and many deck builders use 6x6 posts as a standard, regardless of the height or load of the deck. Though the height of a deck is often questioned only in regard to the requirement for guards, it is a factor in determining the height or “span” of the posts.
Will treated wood rot in concrete?
Pressure treated wood will eventually rot in concrete.not nearly as quickly as untreated, but it WILL eventually.
