Parking Garage/Covered Parking Slopes
Parking Garage/Covered Parking Slopes
(OP)
To all;
I have a quick question. I have a design that the architect presented to me. He has designed a hospital that will be raised and is in the form of the letter T. The parking underneath the top portion of that T I have been able to maintain 1.5% to 2.0% slope to catch basins. However the right side of that T at the base, has been a little tricky. The bare minimum slope that is available is 0.7% from the concrete to the paving and then 1.5% to a series of catch basins. In any of your experience, do you see that this 0.7% is a problem? Again it is going to be well covered and we might get some rain that is blown in but I doubt it will be that much and then carry over from cars driving underneath. Also, the other side of that T is well sloped at 1.5% or better.
What do you great guru's think?
Runoff

I agree with you on the skating portion. That is what I am really worried about. I liked the screed finish idea by Steve which will get the minor flows out of there. If it does flow to the other side, then there will be more of a slope in that area.
Runoff.
RE: Parking Garage/Covered Parking Slopes
If it's concrete and you have a nice finish on it, 0.7% shouldn't present any problems.
Some good contractor can lay asphalt at 1.00% for short stretches without creating "bird baths" or "skating areas", however, I think that is the exception more than the rule. I try to keep it at 1.50% in areas that will be seeing significant runoff.
