Waterproofing Concrete Roof Working Surface
Waterproofing Concrete Roof Working Surface
(OP)
I have a building that requires a concrete roof to allow access to machinery on the roof.
The roof will be used to support equipment and parts as well as hand trolleys or light fork-lift. The roof will also have lay-down areas for placement of machinery parts, etc.
Question: What type of water-proofing is suitable for the concrete roof that will be durable enough to withstand the wear and tear of traffic, machinery and heavy parts on the roof?
Any ideas or experience you can share on this would be appreciated.

Besides protecting the inside of the building from water infiltration I want to protect the concrete roof slab to avoid water seepage and resulting corrosion.
I'm thinking of using brushed concrete surface and a paint-on / roll-on liquid sealant. Roof will probably have 1% slope for drainage.

If you want a roof, do what BA says and utilize a double slab with a proper membrane between. The only times I have done this is where the basement of a building extends beyond the exterior wall line. Not really a great idea in the first place, but that never stopped an architect.

I have seen the same with the waterproofing systems and the foam reversed to keep the controlled envelope tied to the more stable interior temperatures.
