  1. This is what I have to do with my patio. No basement, however the water may come up over the foundation and into the house.

  2. Just soil and shovel-cheapest and easiest way to solve a problem with flooding.

  3. I would first bring a survey scope and plot the terrain on the map. I think swales on both sides of the house to the street could have worked. But hard to tell without a transit.

  4. Where in Kansas do you live? We may need your services? buying a house in Argonia, near Wellington.

  5. Why didn’t you put waterproofing on the wall while it was exposed.

  6. If your going to seal it then seal it caulk those damn things better then that

  7. So what I take away from this is.

    When the building was built either 1 of 2 things happened.

    1. Building was not properly built on the current elevation ( ie too low, not enough footing wall height )
    2. Entire building sunk into the ground.

    My house, circa 1954, is in alot of the same state. I need to unbury my foundation but yard would then be 6 to 8 inches too high.

  8. French drains, sump pumps & water proofing are a last resort. Where does the water go if the foundation is sealed? Get rid of above ground water first, especially roof water.

  9. I just bought a house and it has negative slope plus the exterior grade is pretty much even with the finish floor, there's a concrete ring (almost like a brick seat) going around the perimeter of the rear, outside the floor joists which sit on a ledge (similar to the way bridges are built) and its graded up to the rim. Not sure what the heck I'm supposed to do about that. Worried about cutting it out and then compromising the foundation (the house is nearly 100 years old and the foundation was reused from an 1880s house).

  10. How much does a job like this cost to do?

  11. Hi, can you do a video on ground water?

  12. My negative slope was nowhere near as bad as the one in the video. Nevertheless, heavy spring rains would always flood my basement. In the summer, I collected my bagged lawn clippings and placed them along the foundation, it composts into the soil and builds it up. Haven’t had any water in the basement in over 10 years. The negative slope is completely gone.

  13. Awesome information. Surface water = slope repair. Ground water = Sump pump.

  14. I would have done two things different.

    Instead of calking the wells, which will only last a short time, I would have used a rubber seal for far more durability and better sealing. Also, I would have brought in enough sod to give the area the required amount of grass to protect the soil from being washed away in the next torrential rain. I would also put covers over the wells to keep rainfall from flooding the window wells.

  15. Thanks for sharing nicely explained

  16. How much soil did they bring in for one side of this house?

  17. I have a small amount of water getting into my raised concrete crawl space in my basement. I have a sump pump. It looks like it’s the corner where I have a gutter down spout. I got gutter extenders and built a slope out. Any other suggestions of how to fix the problem. I have a brown spot on the corner cinder wall where the water gets in during heavy rain.

  18. Do you recommend putting outdoor tiles on the positively graded soil to create extra waterproofing?

  19. This was really informative!! I have water issues in my basement but I think it’s a combo of the slope and water seeping up through the floor 😭

  20. If you think you're battling surface water, that's your first mistake…you will need a french drain or a gutter system for thus house in a season or two. Re-grading is a band-aid when the water already knows where it wants to go…

  21. Do they not make the window wells in something that will not rust galvanized would be my last choice

  22. Also talk to your neighbor before and show your plans, You don’t want Neighbor to feel you’re dumping your water into their basement
