Ground Cloth/Underlayment

flexible tanksOne of the most common accessories used with our flexible tanks is a ground cloth, liner or underlayment fabric. Designed as an impermeable fabric material, these liners go underneath the bottom of the tank to help protect against abrasion and wear. Liners are often used to help extend the lifespan of the tank while liquids are in storage.


For both open top and closed top storage tanks, impermeable covers are available to help protect the tank from wind, rain, and outside factors. Covers are commonly used on our flexible frame and onion tanks to help cover stored contents during temporary or long-term storage.
