When the overall lot drainage is toward the house what can be used to direct surface water away from the foundation.?

if I was you I would by a new house unless you like your house flooding Many things must be taken into cosideration. One is the location you are at. You may have local codes that must be met to ok the work that needs to be preformed. After checking into that, use a builders level and shoot grades to see the land fall of the property and just where the water is going. If there is room to fill in the low area from the house to the furthest point out without covering the foundation too deep you can try that. Keep in mind that the spot under the house will be deeper at that point and you my have the result of water building up underneath the house. Another thing you might be able to do is to shoot a grade to the lowest point closest to the house and then find the point frathes fron the house that is at a lower point. Dig a trench from point to point with the grade slope going away from the home. Place a pipe that is suitable to carry the water, this will act as a storm drain. Any water that might be building in the area could also be drained away by putting in feild lines in the same way septic lines are installed, only they will act in reverse and drain the water from the ground instead of putting water in the ground.
