Is a 1/8 inch per ft. slope (away from the house) sufficient for a patio?

by Ron D
I have excavated, graded, compacted, added gravel in 2-inch stages, and compacted again. I've been doing this with a 1/4 inch per ft. slope away from the house. Unfortunately, I now discover that using this degree of slope will not allow me to connect properly with the remainder of my lawn without running into problems with the stoop at the back of my house (a long story). So I 'm thinking of re-grading the last segment of gravel to make the slope a 1/8 inch grade. I'm wondering if this is sufficient for a patio that is northern exposure and often gets a good bit of snow (Denver, CO). I'm also wondering if the 1/8th inch drop will hold up if I compact it thoroughly, given that the early layers were compacted with a 1/4 inch grade. Any info or advice will be much appreciated.

    How big is this patio?...I normally like to see 1/4 or more but once your out far enough from the house it usually does not matter as much. Is this going to be a poured patio or are you going with pavers or flagstone?

    I am using brick pavers. The patio is 16 ft. by 18 ft.

    I think you should be fine...the pavers will allow water to perc through if needed...the trick is to prevent pooling at the house... post some pics when you get in completed.

    Thanks for your help! Will the re-grading pose any problems?

    if you are tamping you should be is when folks skip this step and the fill settles in weird ways where the problems start.
