Safe Tank Abandonment
At M.A.Y. Tank Company, we specialize in abandoning underground oil tanks safely and efficiently using NYS-approved Tripolymer foam. This advanced foam is designed to fill the tank completely, preventing future collapse while ensuring compliance with environmental regulations. The foam’s lightweight yet durable properties allow it to provide structural stability without adding unnecessary pressure to the surrounding soil.
Tripolymer Foam Technique Photos
Tank abandonment using Tripolymer foam is available in both Nassau and Suffolk County. This type of foam requires certification from the Nassau County Department of Health for application. We have been certified for over 20 years, ensuring compliance and expertise in the process.

Tank Abandonment with Sand and Slurry Mix
Long Term Stability
For tank abandonment projects requiring a more traditional approach, M.A.Y. Tank Company offers professional services using sand or slurry mix. This method involves carefully filling the tank with these stable materials after it has been cleaned of all remaining oil and debris. Sand and slurry mix are highly effective at providing long-term stability, making them ideal for larger tanks or those in areas where additional structural support is needed.
Our team ensures the tank is securely filled and the excavation site is properly backfilled and leveled, leaving the property clean and safe. Whether you need foam, sand, or slurry, our expertise guarantees reliable results tailored to your needs.
