  • clay based soil for grading

    I have water in my basement and will try to solve it with grading. I was told to use clay based soil but i can not find it. I found clay. Can I use it instead? If not can I mix clay with soil? What proportions? Thank you

    clay based soil for grading and water control

    If you can't find a clay to add to your soil put a little more "grade" into your grading. If the soil is sandy the water will pass through quickly enough. If it is a sandy loam or "thicker" the water will soak in somewhat... but with a slightly steeper grade the water is going to follow the laws of gravity. You may find you won't need any clay.
