Concrete Deck


I have a concrete deck that covers an interior retail space. I would like to put tables and chairs on it. What can I use to wateproof it that will holdup to this use?

Re: Concrete Deck


Most kinds of low pitch roofing membrane. Use pavers on top of the roofing for traffic.

Re: Concrete Deck


Look at this site from your post at the other site.

http://www.hydrotechusa.com/START.HTM

Theres some cool stuff there. Look at the water droplets on that building. Nice work.

Looks like now they're combining landscaping and roofing.

Re: Concrete Deck


Hydro stop like roofer dude said would work well. Little messy to install though and heaven forbid it rain before it dries. Just coating the concrete with this product would work, but when you coat it, embed the mesh, coat it again let it dry and then apply a top coat, that's a really good seal on concrete. And you can always just re-coat it every so often for maintenance and to fill in any gouges it may get.

Re: Concrete Deck


Aaron,

Polyurea is the way to go. Does your company apply polyurea? Polyurethane Foam?

Re: Concrete Deck


To add to the ideas here I would suggest using a 3 or 4# density SPF with a high tensity strength polyurea of about 40-60mils. If you did that you could have parties on your roof. As long as the roof could hold all of your guests. The SPF system weighs about 8-9 oz per sqft. Being a concrete deck should hold several people and furniture.

Re: Concrete Deck


There is a 30# polyurea foam that would work great for that scenario.

I apply polyureas. Thnking about SPF for both roofing and insulation.

Re: Concrete Deck


I have never used hydrostop but I have herd mixed reviews about it. The only thing I can think of that's cost efficient is gaco 100% silicone and then use pavers. I have not personally done this, but I was told this works.
I have installed gaco on foam roofs and was really impressed.
Good luck, let us know what you come up with. I run into this situation here and there and it would nice to know what you come up with. David

Re: Concrete Deck


Flatroof guy brings up old thread.


Since I loved the year 2006 so much and I was born in July I feel I should comment.

Concrete deck, Fleeceback TPO or EPDM set with Olybond. A pedestal system with a paver of your choice or a single ply manufactures paver directly on the membrane.

Anything like outdoor furniture and a single ply membrane, a coating (Gaco. I keep hearing how great it is I really need to try it) or even an asphalt roof and they will not hold up well. You have to have some kind of protection. Wood deck, pavers, and in one case we even put walk way pads down over the whole thing.
