    french drain and surface drain in one

    Sorry for the late reply, I've been digging during every moment of free time lately. So far I've regraded to the best of my abilities without cutting down any more trees. And I've dug a 12" deep trench about 2 feet wide across my yard at the treeline as a surface water swale. I got some free...

    counter pressure

    Yes, the block wall continues above the slab 20", and there has been some settling, but it is minor. I noticed one wall has detached from the slab slightly and is very slightly off level, which makes me think it has started to move outward so I think any additional settlement from the weight of...

    counter pressure

    I have a 26'x30' cinder block foundation garage built on a grade. The back corner has about 3 1/2' of gravel fill under the slab, and the front maybe has 6". Fill dirt was added in the back to build up the earth about halfway up the wall to give it some counter pressure. I was going to be...

    french drain and surface drain in one

    I was planning on using the white 4" PVC with 3 rows of holes drilled in them to establish a more uniform grade with the pipe (also for easier clean out if necessary) I figure if I use sand for this, I would have to use a sock do to the larger holes. I can't seem to find 3" slotted pipe in my...

    french drain and surface drain in one

    Oldestguy, If I do go with concrete sand fill, would a 12" wide drain be wide enough? I don't have a lot of space towards the back of the garage to do a separate surface drain if I go much wider. also, would it be suitible to top with river rocks for looks, or should a sand drain be covered...

    french drain and surface drain in one

    here's some photos, as you can, my grade to the garage is terrible due to the low door, and the only way to fix that is to cut down more trees, which my wife id dead set against, so an open topped french drain seems to be a better solution. I drew a little picure of a possible cross section if...

    french drain and surface drain in one

    thanks, I'll take a look at your other posts. I was thinking it would be easier to dig one trench. I also have a lot of trees that are going to be an issue if I have more than one drain spaced too far apart. I still think I'm going to run a gravel topped french drain 8-10 feet from the garage...

    french drain and surface drain in one

    thanks for this, this is along the lines of what I was thinking. I had been curious if those "prefabricated" french drain geomembranes worked. It seems like this is a good way to use them, to stop water seepage and as a redundancy to extend the life of the drain.

    french drain and surface drain in one

    thanks for the reply, isn't what you're describing basically a french drain without the geotextile around the gravel? My fear if not separating the surface water from the bottom of the trench is I don't want to worsen my problem by bringing more water down closer to the footing depth.

    french drain and surface drain in one

    I came across this forum searching for information about proper french drain construction. After reading much on the subject I am left with still more questions that I was hoping someone out here could give some insight. First off, I got a detached Garage built over 2 years ago on my property...
