Concrete Slab Cover Ideas?

Concrete Slab Cover Ideas?

Concrete Slab Cover Ideas?

(OP)
So I am in charge of researching and getting quotes for a concrete slab cover. The concrete slab is about 50' x 100' and is contaminated with chemicals that can't get into the water. So to prevent water from getting onto the pad, like rain, a cover is needed. I wasn't sure where to begin with this as all my searching turns up with polyethylene sheets and not much else.

The cover needs to last about 10 years and should be cheap but durable enough to last for those 10 years. If anyone as ideas on what to look for, or ideas on how to better research this, I'd appreciate it.

RE: Concrete Slab Cover Ideas?

Can you use a polyurethane or epoxy coating with a primer? Cleaning the surface may be an issue. In lieu of polyethylene which will not last, can you use an EPDM material?

Do you have to notify anyone of the contamination. Under relatively recent legislation, Engineers can be held criminally negligent, in Canada, for environmental issues.

@Dik, reporting the contamination isn't an issue but thanks for the concern. Cleaning is an issue, it's why the cover is what is going to be used. The cover is supposed to be on top the pad, kind of like a roof or like a large tent one might see at a family gathering where people can sit under. Obviously not exactly like that, but I think you get the idea.

I'll look into the EPDM though!

RE: Concrete Slab Cover Ideas?

I'd re-post under Chemical Coatings forum.

RE: Concrete Slab Cover Ideas?

We have a Chemical Coatings Forum... if it were posted there, I'd have missed it... got it... EPDM is a material used for roofing... it's tough, nearly impervious, and relatively inexpensive and there are numerous roofing contractors in this area that can install it...

Bespoke FRP cover?

Pre-welded Reinforced HDPE membranes will work and are used for this application. Look into the Cover Up 240 (0.4mm thick)

How about two inches of WWR'ed concrete?

RE: Concrete Slab Cover Ideas?

In situations where contaminated soil must be protected from rain water to prevent spreading of the contamination, a plastic or rubber liner is usually used, and then this is covered with clean soil for ballast and protection of the liner from the elements. In your case, I suggest you to mound some gravel on the pad to avoid water pooling and then cover with a liner and more gravel.

White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
White Paper - Model Based Engineering for Wire Harness Manufacturing
Modern cars, trucks, and other vehicles feature an ever-increasing number of sophisticated electrical and electronic features, placing a larger burden on the wiring harness that enables these new features. As complexity rises, current harness manufacturing methods are struggling to keep pace due to manual data exchanges and the inability to capture tribal knowledge. A model-based wire harness manufacturing engineering flow automates data exchange and captures tribal knowledge through design rules to help harness manufacturers improve harness quality and boost efficiency.

White Paper - Modeling and Optimizing Wire Harness Costs for Variation Complexity
This paper will focus on the quantification of the complexity related costs in harness variations in order to model them, allowing automated algorithms to optimize for these costs. A number of real world examples will be provided as well. Since no two businesses are alike, it is the aim of this paper to provide the foundational knowledge and methodology so the reader can assess their own business to model how variation complexity costs affect their business.
