Tank Farm Dike Concrete Liner - Expansion Joints
Tank Farm Dike Concrete Liner - Expansion Joints
(OP)
I'm in charge of designing a concrete liner for a fuel tank farm. Base material is clay, the concrete liner is going to be 5 inches with wire mesh plates. I'm thinking of contraction joints every 10 feet and expansion joints at the toe of the dikes and pipe supports.
I'm not sure of the spacing between expansion joints though. I have clay as a base which might buckle the liner with the inherent expansion/contraction of the clay, but I must also make the liner with as few joints as possible to maintain the integrity of the liner in case of a leak and/or fire.
Anybody have any advice?

If you're worried about clay swelling, ask your Geotechnical Engineer how to mitigate that.
A 5 inch slab with mesh sounds like a dressed up sidewalk.

My question is if expansion/isolation joints would only be needed on the toe of the dike or a minimum spacing between them or none at all?

What about the provision for increased runoff from stormwater? Has the present system been designed for this scenario already?

There's no increased runoff since the clay doesn't let the water percolate and the dikes need to get drained after every rain. Anyway, the effluent plant has more than enough capacity since that was the design parameter.
