Thanks for all the replies. Mike Halloran: About the cement dusting, I wonder if you could post, or send me a picture of this. Is it a solid layer of cement, or just a light dusting that gives the appearance of a wash? Does it look like cement, or more gray, like weathered asphalt? And, what is...

Hi, I am wondering if it is possible to have gravel rolled into the surface of asphalt as its being installed. The purpose is simply for aesthetic reasons. I don't really like the look of a solid black driveway. I've looked into getting tar and chip, but, there are very few people who do that...

BigH - The french drain was built with a pipe, holes facing down, connecting to a solid pipe that the gutter leaders and sump pump tie into and runs out to a stream at the back of the property. The french drain is only in the front of the house. It has gravel surfacing to the top. No soil on...

thank you. That was the direct, to-the-point kind of reply I needed to hear. Really, it was my question that needed to be more direct. With all my convoluted calculating I didn't ask the direct question. Anyway, no, there is no water coming into the basement through walls. That was taken care...

I'm rereading this whole thread and see that I asked before why one wouldn't want surface runoff going into a french drain, but I realize I still don't quite understand why. Is the simple answer that not enough of it gets transported away in the slotted pipe? I understand not feeding a gutter...

Yes, I probably have been over calculating, but was just trying to quantitatively understand how well a French drain removes water, and where the water is coming from. When we talk about subsurface water, does one mean 1 foot down, or 5 or 10? With a ditch only 1.5 feet deep, how much...

I don't know if any of you are familiar with the "Ask the Builder" website. Here he explains water movement through soil and using the french drain to protect ones foundation. "When it rains, water enters soil and pushes the air to the surface. Gravity then takes over. If your yard slopes, the...

How does one determine where the water table is? I assume to lower the water table, the french drain has to be very deep.

ah, yes, I totally forgot about all the space taken up by the gravel. thanks.

But, if the french drain pipe is on 4" of gravel above the bottom of the trench, doesn't the trench have to fill up with 4" (actually 5" since the holes are a little off the bottom) of water before it gets to the pipe? At the dimensions of the current trench (28" wide x 25 ft. long) it would...

Sorry, this is kinda long, but I'm just trying to understand a couple things. It seems as though a lot of people on this forum aren’t so in favor of using a shallow French drain to collect, move and divert water from running towards a house where the property slopes towards it, yet, a lot of...

Thanks for the response. You were clear the first time, but that drain was already in. And, the contractor already fired. Though, that was due to other sloppy work. If I were doing this project again, I would first hire an engineer to design the plan, and not just hire the guy who calls himself...

Thanks for the replies. We are fairly limited in how much we can grade away from the wall since there are some big trees about 10 - 12’ in front of the house, and getting too close to them would cause a lot of root damage. We had already created a bit of a swale about 5 feet in front of the...

Hi, I have a couple questions about french drains. Our property slopes from the street down towards the house and the house sits quite low in the gound, so, not surprisingly, water has always been an issue. We're putting in some french drains in the front of the house to intercept the water and...
