Does anyone have any experience with french drains under a brick sidewalk? I have two downspouts which unload onto the brick sidewalk in front of my house. I probably spend 30-40 hours every winter chipping ice so people (including me) don't kill themselves in front of the house. The brick there is at an angle, so it's very easy to slip. I was thinking about running a perforated pvc pipe, french drain style, under the sidewalk and tree lawn to eliminate the problem. Anyone tried this, or something similar. I don't want to just french drain them into the ground, because it will just come back into the basement.

Thanks for the tips. Do you ever have problems with them backing up due to very heavy rains or winter freezes? I really want to be able to go under the sidewalk, but I don't want to ruin the bricks either or create a different issue because the bricks are heaving when the drain freezes. Also, how far away from the house should the pipe run?

When I put in French drains, I dig a trench 1' deep by 8" wide. The walls and base of the trench are lined with 5mil poly. Perforated pipe covered with a fabric sock, to prevent silt from clogging the drain holes is then installed, followed by a layer of crushed stone. All drains lead away from the house, in some cases do a dry well on the property.


I installed a system just like this last month. Before the rain spout was dumping out right next to the house then flowing into the basement. I did a line about 25' long and we have had several heavy rains and so far no issues. The line more or less runs parallel to the house along the planter. I couldn't go strait out due to grading.
