Double Wall Tanks are an excellent containment solution. These tanks have an inner primary storage tank and and an outer secondary tank that encloses the bottom and sidewalls (part or all) of the primary tank.  Our double wall construction is completely sealed so that dust, rain and snow cannot collect in the outer containment tank. 

We have tanks with up to 10,000 gallons of primary storage and we will soon offer 12,000 gallon and 15,000 double wall tanks.  We can provide double wall tanks that are rated to either 1.5 or 1.9 specific gravity.  We outfit our tanks with the fittings that you need, where you need them. 

We offer tanks as small as 25 gallons. Our smaller double wall tanks are ideal for "Day" tank systems.   By combining our rotational molding capabilities with our plastic fabrication and welding, we are able to offer you an extremely wide variety of double wall tanks.

We also offer some double wall tanks from a variety of resins.  We offer all of our double walled tanks in HDPE (high density polyethylene).  We additionally offer many of our double wall tanks in Crosslink Polyethylene, Polypropylen, PVDF (Kynar) and Nylon 6.  In some cases, we can offer double wall tanks with different plastic resins for the inner tank and the outer tank.

Our double wall tank fittings are installed per your specifications.  We strongly urge that all fittings be placed on the top of the tank and that there are no sidewall penetrations.  The most popular fittings for double wall tanks include a level gauge (so you can see how much liquid is in the primary storage tank), a top-fill line equipped with a siphon tube (so liquid can be pumped into or out of the primary tank), and, a screened U-vent (to keep from forming a vaccuum in the tank). OSHA ladders are another popular choice.  We can equip the double wall tanks with flanges or threaded fittings

We normally have the primary and secondary tanks in stock for our double wall tanks. We mate them, weld them together and outfit them per you specifications.  Lead time will vary depending on the size of the tank, fittings required and current shop load.
