FREQUENTLY ASKED QUESTIONS

If I don’t have a concrete pad what do I put under my tanks?

Tanks are fine to sit on undisturbed soil or compacted soil (if soil has been disturbed).

Can my storage tank(s) sit directly on top of liner?

For fiberglass or steel tanks we recommend the use of our Plia Pad to act as a buffer between the tank and liner. Smooth-bottom Poly tanks may sit directly on top of liner.

How can I fasten my tanks to the ground?

  • You can cable your tanks to anchors outside the containment area or to sturdy perimeter walls.
  • You could pour a concrete base (14’ diameter by 6” deep) on top of the liner and anchor tanks with anchor bolts.

How long will my liner last?

Liners can last as long as 20 years. Common factors in liner failure are punctures, which can be repaired with a hand leister heat gun. Sunlight is another limiting factor in liner longevity, liners covered with pea gravel tend to last longer than those exposed to the sun.

What are sand tubes and why are they needed?

If you choose to not cover your liner in stone, sand tubes are used to act as ballast to keep your liner in place. These sand tubes are made out of the same durable material your liner is made out of and will last just as long as the liner.

What will act as a sump for the containment area?

We typically will install a sump box in one corner of the containment dike. Our stock size is 2’x2’x6” and the sump liner will be prefabricated and seamed into the liner during installation. Excavation will need to allow for a 1” fall over every 20’ in order for rainwater to flow to sump for collection.

What are containment requirements?

The bare minimum in most states is 110% volume of the largest tank it the containment dike, less the displacement of additional tanks inside the containment area.

What products can I contain with liners?

Our polypropylene liner will work for containment of most fertilizer products (28 or 32 % UAN, Starter fertilizer, and liquid potash, as well as others). The polypropylene liner also will work for containment of ice treatment products (sodium chloride, magnesium chloride, calcium chloride, etc). Our XR 5 liner is used for containment of petroleum products such as diesel, gasoline, fuel oil, etc. Our 1936PTF material is used for containment of solvents more caustic ag chemicals.

Can I put rocks inside of the containment to set tanks on?

Yes, but we recommend adding a layer of geo-textile fabric between the rock and the liner to act as a buffer to avoid penetrations. This avoids the need for sand tubes, and also allows for a uniform tank base as well as a clean walkway.

Do you travel outside of Indiana for installations?

Yes, we travel nationally!

What are my options for walls?

  • The Plia Dike containment system includes galvanized walls and angle braces that require a cement bond beam to create the equivalent of an 8” cement wall.
  • Large cement blocks, an example would be 2’ x 2’ x 4’
  • Poured cement with a footer
  • All of these options save the customer the cost of pouring a cement floor.

How long is the installation processes?

Once the walls are set the installation of the liner, sump, sand tubes, takes less than one day.

What information do you need for to form a quote?

  • Diameter and size of tanks
  • Suggested footprint and wall height
  • Type of material to be contained
  • Selected type of walls to be used
