Category: Crawl Space Repair, Structural Support Replacement
Problem:
A homeowner in Islip, NY had rusted and deteriorated Lally columns in the crawl space of their property. Over time, moisture exposure had caused the steel supports to corrode, reducing their load-bearing strength and compromising the stability of the home’s foundation. This posed a risk of uneven settling, structural damage, and long-term safety concerns. The homeowner needed a durable, rust-resistant solution to restore the crawl space’s structural integrity.
Solution:
The Zavza Seal team carried out a complete replacement of the damaged supports with high-quality, long-lasting Lally columns.
Work Scope:
- Removed the existing rusted Lally columns from the crawl space.
- Installed eight new 4-inch diameter concrete-filled steel Lally columns, each fitted with top and base plates for maximum stability.
- Ensured all new columns were factory primed with a rust-inhibitive coating to prevent future corrosion.
- Applied a final finish coat of exterior-grade white enamel paint to protect the steel and enhance the crawl space’s appearance.
This combination of factory priming and enamel finishing ensures the columns are well-protected against moisture in the crawl space environment.
Outcome:
The installation of the new Lally columns restored full structural support to the crawl space, significantly improving the safety and stability of the home. With corrosion-resistant finishes, the new supports will provide long-term durability, reducing the risk of future repairs. The homeowner can now have peace of mind knowing that their home’s foundation is well-protected against settling and structural issues.
