Our house is two years old with a concrete block wall foundation. Approximately six months after we moved in, we experienced water seepage through the concrete block walls after a heavy rain. We noticed puddling in the yard at that corner of the house, so we proceeded to regrade the yard away from the house. We also installed underground piping to divert all downspout and sump pump water away from the house and down to the stormwater catch basin. We also installed gutter guards to prevent the leaves from clogging the gutters. Now, the water seepage is still occurring in the same location on the wall, but has moved down to the joint between the slab and wall. We checked the footer drain with a "snake" and everything seemed clear. Also, several moisture spots have appeared on other walls of the basement.

We had planned on finishing off part of the basement, but will not do so until this water/moisture problem is solved. Could you please give us ideas of what the problem could be, as well as any possible solutions?

Greetings,

You did not mention if this is a new development or not.

Go down to the Town/City Hall and find out what used to be where your two year old house is now.

I know many homes have been built in filled wetlands. If this is the case, you are in for a long and expensive ride.

Please provide more information.

Good luck,
Jason

Our house was built on agricultural fields (possibly corn fields). We do not live in a "development", but our house is on a 2 acre portion of the former field. Our lot is naturally level, so I don't think that we have much fill.

Our soil is a consistently dense clay with a deep reddish-brown color. Can water form paths or cracks through this type of soil? We also have a swale in the backyard which is about 20' from the back wall of the house. After rain, the swale becomes soggy and puddles. Could this be the source of the excess water seepage in the basement? If so, would a french drain located in the bottom of the swale help?

Sounds like you lost whatever they used for a seal around the blocks. I think you are going to need to reseal around the blocks for any long term repair. The best repair that you can do yourself is to buy an injectable sealant that expands on contact with water, inject it into the seams in the leaking area. Use a water hose and flood the area outside where you think the water is getting in to make sure you got all the leak. I saw a repair kit in the Home & garden section on E-bay it was called "Concrete leak repair kit" Good luck

You may also check the slope of the soil near the house. If it slopes down toward the foundation level it may be seeping through. In that case you may speak to a mason or landscaper to redirect the water flow away from the house instead of toward the house.

The solution to your problem has a fix but will need to be done by a reputable contractor. I do need more info in order to give you a scope of work to repair the problem.
1) what type of water prooffing did you use on the foundation wall
2)do you have a sepitc bed
3)Monitor your sump pump and tell me if you can see water pooring into the pit from the opening.4) Is your weeping tile sitting at the foot of the foundation footing ouside your wall or inside.
Iam a strong believer of block wall foundations but in order for this componet to work there are many types of material and componets to use in order to have a superior wall.Injection sealers will not work on this block for many reason to large to list. Please get back to me as soon as possible by a reply or e-mail.

Thanks for the replies everyone. I will try to address them the best I can.

Chuck47h: After we started having seepage problems, we regraded the yard behind the house to better define the swale and redirect the water away from the house. We still have the seepage problem, so either we didn't slope it enough or there is another problem.

Robert Fieder:
1) Unfortunately, anything on the exterior of the foundation wall is a mystery to us b/c we bought the house after it was already built. So, we're not sure what kind of waterproofing was used. Interestingly enough, another house built by the same builder has hired a basement dewatering company to fix their problem at the cost of $10,000.
2) Second, we do have a septic bed, but it is located on the front of the house where we don't have seepage problems.
3) We're unsure if water pours in the footer drain at the sump pump well. We've "snaked" the footer drain piping and didn't find any obstructions, however the snake did come out with sediment covering it. There is also sediment laying in the footer drain pipe at the opening in the sump pump well.
4) I'm not sure what weeping tile is, but if its on the exterior of the house we won't know until we dig it up. I am interested on your thoughts about the weeping tile, though.

We are do-it-yourselfers and would like to exhaust all avenues before resorting to digging up the foundation wall if at all possible.

Thanks again for your replies!

If you provide me with an e-mail address and fax # I will give you plan view details of a typical foundation wall detail, and scope of work to repair your problem.There is a product in Canada a product that is far more superior than any other product Ive seen you can obtain. I think it is available in the US I will send you there web site and documantation on there product. Also I almost possible that the your house is built on a higher water table. It sounds like you may have hydrostatic pressue build up under your concrete floor which is quite common if all the buiolding componets are in place.I can also send you a plan detail to repair this too. Unfortunally It sounds like you may have no options but to procceed with excavating the foundation wall if you want to repair the problem. Ive been involved with many situation like yours and have repaired the problem. I will fax to you.Also see what the contractor is doing to your neighbours place.If they are de-watering than,for sure there is a high water table in this area. but don't be alarmed the solution to your problem is simple and may cost some dollars to repair. But you can be rest assured that it will work. Also find out what the local building regulation require for foundation and footings.On this property.The builder may be responsible if he did'nt follow the building code which means that he could be responsible to pay for any repairs.

Hi, I am having some problems in my basement. Im pretty sure I know that the water is coming in at and how to fix it. My question is though, i just got done finishing most of the basement. The amount of water that came in left a 2'-3' wide stream from one end of the basement to the floor drain which is about 40' away from the far wall. The walls it came in through are block walls with 2x2 furred walls with stryofoam and beadboard insulation in them with drywall on top. The water has 3 walls to go through before it gets to the floor drain. This is the first time the walls have gotten wet, and I am going to go downstairs right now and use a wet vac and fans to dry off all the floor area I can. I have heard alot about mold and mildew in cases like this, will I have to replace all the furring strips/studs/sills/insulation/drywall? Or will this one time incident not be of concern for mold? Let me know your thoughts, I can do most home construction, but mold and mildew are not familiar to me yet.
