| Hell all. I'm new to this site. I have a problem in my basement. Whenever it rains, I get water coming through the block, motor joint and up through the floor. It's a block wall, with a ruff racked slap floor.
I'm looking for an affordable rubber waterproofing paint.
Any names or sites I can hit would be great.
Thanks,
Mike.

Waterproofing paint will not help for long. From your discription, there is little or no waterproofing on the outside of the blocks. An raw block is nothing but a large sponge. They will soak up and hold water for extended periods of time. Putting the paint on the inside simply stops the water inside the blocks. The hydrostatic pressure will eventually cause the paint to turn loose and bubble up on the walls and floors. These bubbles will burst and the water will enter the basement. I once saw a basement with seven coats of different waterproofing materials, and water running accross the floor. Save your money, and look into either exterior remediation, or an interior baseboard drainage system. If the floor is cracked and seeping water, the only real solution will be a drainage plane with another layer of floor over. Don't waste your time on the paints.

Thanks Shelby.
My house sits on a recessed lawn, causing water to run down towards the hose. I poured a concrete patio in front of the house. I even tared the front wall, back filled, to push water away from the house. Kicked out the drains farther, and even poured a small footer wall and added a landscaping stone.
Dont want to do the paint thing. but been seeing this new rubberized paint. It's alot of $$$$ though.
I'll add a pict. |

You can see how the house sits down hill. I even get water on the drive way side as well.
I have no idea where the water comes in at. I actually think that the block fills with water, and then just fills up and works its self around the house.
A cheap fix I guess, but I thought of drilling a hole in the crawl space....in one of teh blocks and adding a drainage tube from the wall to the drain pump hole.
It looks like some sort of french drain was installed. I see new concrete along the inside of teh crawl space. Its really ruff though. |

You are right about the blocks filling with water, and they will hold that water for a long period of time.
It appears that the area next to the garage is a 1/2 level below the main entryway. Is there basement under the area to the left of the entry? Is this the problem area? Do you have problems with the area next to the garage? Does the yard fall away from the house in the back?
It sounds like a french drain system of some fashion was installed. Does it lead to a sump pump? If not, where does it drain to?
Unfortunately, most of the surface exterior fixes you mentioned will not affect the ground water problems you have. In fact the poured concrete patio may actually make the problem worse. It doesn't allow for surface evaporation of ground water under the concrete, and so this ground stays wetter for a much longer period of time.
Your thought of drilling a hole in the blocks to drain the water is, actually, not a bad idea. But you must drill every cavity of each block, as they are not interconnected. It is part of the remediation process used with the baseboard drainage systems. Check out www.bdws.com.
Without an onsite inspection, its hard to further diagnose the problem and offer any firmer suggestions. Water problems can be the most frustrating things for a homeowner to deal with. Maybe this will help some.

Painting the basement walls is only a band-aid, like others said. You want to fix the problem. If water continues to fill in and around your foundation, this could cause hydronic pressure to crack the foundation and eventually the foundation will push in towards the middle of the basement wall. Especially if you have cold winters... the water around the foundation will freeze causing the walls to crack from the pressure and the walls could push in over time.
Any idea what the soils are around the foundation? If it is all clay, that will hold the water and not allow it to make it's way to your drain tile and sump pump. The standing water eventually makes it's way into your foundation through cracks, etc.. Preferably you want sand back filled around the foundation, this will allow the water to go down easily to the drain tile and to the sump pump. |

Thanks guys.
I just built the garage this past year. I added in a drainage system in front of the garage.
The first window along the driveway is a bathroom, and the wall of that room facing the drivay gets water, along with the whole front of the house.
The new pad and walkway was done just a few months ago. It has great pitch and run off.
As you said, it frustrating. Water can be getting in anywhere and just filling up all the way around the house.
Gonna add a porch roof across the front of the house. that will kick the water a bit further away from the house.
Great site and great help.
Mike. |

| Oh yeah. as far as the soil goes. There isnt much soil. It;s a tuff clay like ground. Hard as hell to dig anywhere in the yard. |

Mike, the problem with block walls is that they are HOLLOW. Even if you could find a rubberized paint to adhere to the inside walls, you still have to worry that the hollow block cores are still filled with water. A rubberized paint would only trap that water in there and probably cause more damage.
If you are intent on trying to fix this problem from inside, there are companies that make a polymer type waterproof sheeting for the inside walls. It requires drilling drain holes into the hollow cores of each block to release the trapped water. These holes have to stay open or connected to a sub floor drain system. There's some info on this site about basement wall leaks . On the bottom of that page is a link to another page with some good preventative advice.
If you want a rubberized coating for the outside, you'll have to dig out and clean the foundation walls. A good product called Rubber Wall is hot sprayed on. Another one similar is Owens Corning Tuff & Dry. The only caution to digging up the outside is that you might make this problem worse because the newly loosened soil is more penetrable by surface water. I've seen basements that were dug up that now leak mud.
Look into extending your rain gutters and making sure your outside yard is sloped away from your home so no water ponds near the house. Hope this helps. |
