Concrete Sealant for Secondary Containment
Concrete Sealant for Secondary Containment
(OP)
Hello, I need help in finding a concrete joint sealant for a secondary containment structure. The sealant will be used on horizontal slabs and on vertical walls, so a self-leveling sealant will not work. The structure will serve as secondary containment for fuel tanks, so it must be fuel resistant. The structure will be outdoors in Kansas, so it must be able to handle a wide variety of temperatures. I would like a sealant that is easily applicable, so that the owner may easily inspect and maintain the joints. Some of the joints will be expansion/contraction joints, so the sealant cannot be brittle.
In summation, I need a sealant that has the following properties:
-non-self leveling (for use on horizontal and vertical concrete surfaces
-fuel resistant
-wide range of service temperatures
-easily applicable
-flexible
Thanks for any input, it is appreciated!

I don't think a sealant will cut it. If the concrete is poured, you'll probably have to line it.

Am I understanding the requirements of 40 CFR correctly??

I'll research this further.

Let me know if this is not how anybody else interprets it.
With that said, if I am under the Part 112 requirements, than I don't necessarily need a chemical resistant water stop or a impermeable liner on the concrete surface. I may still use a water-stop, but I thought that if I use a key-way between my wall and slab along with L-bars, if I have then use a joing sealant than my structure should be impervious for 72 hrs.
Any other thoughts?

I shy away from coatings whenever possible. Many more bad experiences than good.
