Job Stories From Leetsdale, PA
Rotted Wooden Deck Posts Replaced

To address the issue of rotted wooden deck posts, we implemented a technical solution using concrete sonotubes. These sonotubes were chosen for their durability and resistance to moisture, ensuring a longer lifespan for the deck's foundation. By replacing the wooden posts with concrete sonotubes, we eliminated the risk of rot caused by prolonged exposure to wet soil.


One key advantage of using concrete sonotubes is their cementitious composition, which makes them impervious to moisture and rot. This means that even if the sonotubes come into contact with soil, they will not degrade over time. Additionally, the sonotubes were recessed deep into the ground to mitigate potential movement caused by freeze/thaw cycles. This ensures the stability of the deck's foundation, reducing the likelihood of structural issues in the future.


Furthermore, we opted for a 12-inch diameter concrete pile to completely eliminate any wooden components in the subterranean section of the posts. This decision was made to maximize the structural integrity and longevity of the deck foundation. By using a larger diameter pile, we increased the load-bearing capacity of the support structure, enhancing its overall stability and resilience.


Additionally, the concrete piles were extended 6 inches above ground level to prevent water from coming into contact with the wooden deck support posts. This strategic elevation helps safeguard against moisture-related damage and prolongs the life of the wooden components.


In summary, the implementation of concrete sonotubes with a 12-inch diameter and proper recessing and elevation techniques has significantly improved the durability and stability of the deck's foundation, ensuring its longevity and structural integrity for years to come.
