I have 4 70ft diameter x 40 ft tall tanks, 4 ft apart, applying 5,000 lbf/ft2 each on clay down to 120 ft. No ringwall. Tanks have sunk 4ft over 40 years and need to be raised and leveled. What type of foundation is recommended?
There are 4 tanks placed 6 feet apart on clay soil 45 years ago. No foundation. They were filled with water and sunk 1 ft. This was the "expected settlement. When filled with a product 1.5 times as heavy, they began to sink and tilt in toward each other several inches. Tanks were drained and mud...
Hi folks. What are you to do when a tank exceeds the Out of Plumb measurement per API 653of 5"??? This is a 70 ft diameter x 40 ft high tank, leaning 20" on a clay soil. HELP!!!
Is there a requirement to relevel?
