Basement Problems

I have been in my house for close to 3 years. About 4-6 a year we get some water in our basement. Nothing signifigant, but I would rather not have it at all. Is there a way to water proof without digging up the foundation?

Also, how would I know if there is mold in the basement? How do I remove it? Thanks for the help.

To decrease the water in the basement, start at the exterior and install gutters, downspouts and long downspout extensions (10' minimum). If you don't like the look of the ectensions, run them underground and finish with "bubblers" in the lawn. Then make sure you have postive drainage (away fron the house) to keep all surface water away from the house and the "swimming pool" that was dug for the basement.

After that, the most common water entrance is the joint between the wall and floor. Open it to a slight "dovetail" and force fill it with hydraulic cement (available even at big boxes). Next coat the walls with a product like Thoroseal (pancake batter consistancy) that does not work like Drylok (a paint-type product).

This should take care of the common leakage. If you have a severe water problem, the next reliable step would be to tear up an 18" wide strip of concrete inside the basement and install drain tile leading to a sump with a sump pump.

if the leak is from a crack which you can locate and identify... easiest thing is to do those "hydraulic cement" against the crack and see what happen... this is basically the step the builder will do for new home warantee.. which they did for my house as we bought it new... and that usually works... it's been close to 2 years after the builder repair one leak in our basement and it is ok and no leak...
