Plastic Liner Between Outdoor Flat Bottom Tank and Concrete Slab
Plastic Liner Between Outdoor Flat Bottom Tank and Concrete Slab
(OP)
We are going to install several flat bottom carbon steel tanks (approx. 15 ft diameter) on a big concrete slab at a outdoor environment. The liquid stored in the tanks is not corrosive. The tank bottom (exterior) has been painted already. I wonder:
(1) if there is need to put a layer of plastic liner on the top surface of the concrete slab under the tank bottom. Would this provide extra help on reducing the corrosion? If we do need, what is the material and thickness that are normally used?
(2) if there is need to seal the tank bottom edge on the concrete? This will help to prevent (or at least reducing) rain water from leaking into the space under the tank bottom. If it can help too, what is the sealant that is normally used at this application?
Thanks.

When I looked for the asphalt impregnated expansion joint material, I found many that meet the ASTM D994 standard. Can I use this ASTM D994 material? I don't know the difference between ASTM D994 and ASTM D1751.
Is there any drawback(s) of using this 1/2" thick asphalt impregnated sheet under the tank, except extra cost? Is this a popular way for putting steel tank on the concrete slab?
Thank you.
