Underground Storage Tanks

Custom Underground Fiberglass Storage Tank Solutions

We manufacture customized underground storage tanks at Fiberglass Tank Solutions to meet specific application needs. Each tank is engineered to industry standards with precise customizations, including market-specific accessories, piping systems, and anti-flotation features.

We Are The Underground Storage Tank Experts

There is a reason why the word “Solutions” is in our name. Every Underground Fiberglass Storage Tank we build has its own set of unique conditions, features, and customization to meet the tank’s intended application. Fiberglass Tank Solutions builds CUSTOM underground tanks with market-specific accessories, piping systems, optional equipment kit-up, and anti-flotation systems. Our tank designs are professionally engineered (P.E.) to industry standards and include complete Finite Element Analysis as a blueprint for manufacturing. We provide buoyancy calculations and can also offer P.E. Stamped designs for over 40 States.

From your initial contact with our knowledgeable and responsive sales team to manufacturing by our experienced workforce through the final tank delivery coordination, we promise that as our customer, you will get the personal attention needed to provide a successful underground water storage tank installation.

Powerful Underground Water Storage Solutions

Underground Fiberglass Storage Tanks Resist Corrosion

There can be a wide range of products that need to be collected and stored in underground tanks, and some of those can include contaminates that are corrosive. Water can be corrosive, especially to steel and concrete. When you add other conditions such as high or low pH conditions, increased temperatures, and other process byproducts, chemicals, all of these added elements can create highly corrosive conditions. Fiberglass tanks are built with thermostat resins that can be specifically formulated to offset these unique corrosive conditions. These tank properties allow for a tank installation that will far exceed the life span of other steel or concrete products.

Fiberglass tanks are stronger than steel or concrete for underground applications. Fiberglass Underground Storage Tanks are built to withstand upthrust from ground water, offset sidewall buckling from soil loads, and can withstand H-20 traffic loads. By nature, fiberglass tanks are flexible and utilize geometry and sandwich laminate construction techniques to provide proven designs for underground applications. These designs are mathematically calculated and manufactured with quantitative industry safety factors. As an example, our standard tanks are designed for 7’ of bury, fully flooded to grade, in an empty condition. We also builds underground storage tanks for deep bury applications, exceeding 7’ of cover.

Unlike concrete, fiberglass is 100% water- tight and testable. For applications in wastewater, potable drinking water, and fire suppression, this is a mandatory requirement. Fiberglass Tank Solutions Underground Storage Tanks can be built with pressure testable man-ways or they can be hydro-statically tested in the field to provide proof of function. We also build custom Double Wall tanks suitable for a variety of applications. In certain chemical or hazardous capture tanks, a continuously monitored double wall tank is required to satisfy stringent regulatory requirements.

Benefits of Underground Fiberglass Storage Tanks

In many cases, underground fiberglass storage tanks can provide significant advantages over above ground tanks. Here are a few benefits that may be relevant to your specific situation:

If you need to store a large quantity of water, an underground water tank may be the perfect solution for your industrial or business application. There are many benefits to using an underground water tank, including the fact that they are often less expensive than above ground tanks, they are more aesthetically pleasing, and they can help to protect your stored water from contamination.

Engineered Anti-flotation Systems for Underground Fiberglass Storage Tanks

Tanks with inadequate cover and high groundwater conditions can easily become buoyant. Anchoring systems and proper soil back-fill are common ways to offset flotation of underground storage tanks. Fiberglass Tank Solutions offers three options when it comes to anchoring systems. All three of these anti-flotation systems can be provided with structural and buoyancy calculation with P.E. stamps for over 40 States.

Concrete Deadman System

Concrete Deadman System

As an industry standard, Fiberglass Tank Solutions provides a conventional concrete Deadman system. Concrete has been used for tank anti-flotation systems for over 50 years and is a time proven system. Our concrete Deadman systems are engineered for structural strength, have adjustable hook points, designed and manufactured in house, and come in a tapered design to easily ship with most tanks up to 10’ in diameter. Concrete Deadman systems come complete with everything you need in one place: anchor points, turnbuckles, and straps to provide a fully integrated anchoring system.

TankAnchor™ is a Geo-composite comprised of a coated high strength polyester geogrid bonded to a polyester non-woven geotextile, designed for superior anti-buoyancy resistance for installation of underground storage tanks.

As compared to conventional concrete Deadman systems, TankAnchor™ provides an anti-flotation system with higher safety factors, and shallower bury depths for both single and double tank installations. This anti-flotation method does not require special tools, is manufactured from corrosive resistant material, and is less costly than conventional methods.
