    Patio leaking water along foundation wall into cellar
    I have a concrete patio that is pitched back towards the foundation and water pools against the foundation and leaks down the outside of the foundation and onto the cellar floor. Does anyone have a suggestion how to correct this.

    Of course the proper way to solve this is raising your patio floor, and provide an angle that forces the water away from the foundation and cellar walls.
    In the meantime you can temporally - REPEAT : TEMPORALLY - stop this leaking by trying to block leakage to foundation and walls by providing - if the patio floor is water tight - a seal where the patio floor meets the foundation/walls.

    My patio with similar problems (built level with no slope to drain) was brick laid loose with sand to fill voids, on top of about a 5 inch concrete slab. The water leaking in to crawl space destroyed about one foot on the ends of 8 joists, which had to be replaced.

    We removed the bricks, sawed the concrete and put in an underdrain (gravel and 3 inch perforated pvc pipe) about 30 inches away from the house and parallel to the house. I think we used flashing under the pipes and up the sides of the trench to try and avoid causing water to travel toward the foundation, and cause problems lower down.

    We had the bricks to put back to cover the trench in the concrete. And I realize the integrity of the slab is compromised but the water inside will cause much greater damage including attracting termites and mold and fungus problems.

    We later had problems with ponding (and ice) in the center of the patio and had to do another shorter drain by similar means.

    We protected the outlet ends of the pipes by drilling weep holes in a reg pvc cap, to prevent rodents from building nests and plugging the pipe. We had enough elevation to have fall to the outlet but I think a french drain type installation would prob work depending on soil type.

    All this because some builder was unaware of the basics. We checked with a builders level, the original patio met pool table specs.

    We moved about 6 years later but there was no more problem whatsoever.
