Hi folks, I have been reading all of the threads involving brewery floors and trench drains, but every brewery is different, so here is our setup. I would love some advice on doing the floors right from start to finish, everything from cutting the drains to choosing the right floor coat. Obviously cost is a concern but we don't want to cut corners.
Below are some shots of our building and a close-up of the brewery section. The entire building is 40x64 ft. The area we plan to coat for the brewery is approximately 25x25 ft. in the upper right hand corner. We'll have a trench running all the way down between the brewhouse and the first row of tanks. The other side of tanks will just have a hole drain, for now, because of budgetary reasons. If we fill that side up with 20 barrel fermenters later, we'll put another trench on the left side of that. We will to a 4" curb around the top and right side of the brewery area along the wall. I was also thinking of putting a small "speed-bump" style curb around the bottom and right side to keep the water and effluent in the brewery area.
The slab we are working with is really thick. It's a little "wavy", but the area we core samples was 10" of solid concrete.
How do we properly slope our floor? One strategy suggested to us was to cut a 6 ft. wide swath in the aisle between the brewhouse & fermenters, install the trench drain, and re-pour the floor in that area to slope towards the drain. That would still leave us some dead area under the tanks with some low spots, but it would be pretty good.
Or, should we just cut a narrow aisle for installing the trench drain, and then grind the whole floor down to slope towards the trench? We certainly have enough concrete. I don't know how expensive this is though, or if it costs more to grind down than to pour and slope on top of the existing concrete? If we were to pour on top, how thick of a layer of concrete do we need?
Speaking of trench drains, I would be interested in doing the kind that are formed concrete, and getting that coated when we do the floor coat, and then using SS grates on top. Any brands recommended here?
The floor coat we are considering is called Dur-a-Flex (dur-a-flex.com). Looks like they have done some breweries but I need to check their references. Has anyone used it?
Lastly, do people normally install a P-trap at the end of their trench drain? The reason I am asking is, our trench drain will flow out into a lift-station and get pumped to the road. So I have some concern with gnarly smells / germs coming back into the brewery through the drains (this was a problem at the last place I worked that I'd like to avoid).
Feel free to give me feedback on the overall design too, if you see any drains that you'd place differently or add.
Thanks!
