This is a great site and am glad i found it, what a wealth of info for the avid do it yourself home owner. Unfortunately i have a situation where i need to look for a professional to address my problem....

I have water coming in where the wall meets the floor in my basement and maybe 5-12 inches away from the wall. It appears to be coming up throught the concrete floor which is covered by tile,as well as where the wall meets the floor. Unfortunately the walls are not exposed, they are cover by knotty pine. Basement is finished on this side.

I need to resolve this problem and after doing everything i could do on the outside, clearing drains, regrading,etc,i need to hire a waterproofing company to come in and install what i believe is a french drain system along the wall.

I have a few questions: is it possible to do this w/ out removing the knotty pine?? IOW, can they dig say 5 or 6 inches away from the knotty pine??Or is it better to get under it by taking it down? Also is it bad to have a floating floor when all is said and done? How important is it to drill holes in the bottom layer of cynder block to release water??? one company urges this be done and another says it is not necessary. Does water really come in as a result as hydrostatic preasure or is it more of a high water table problem??

Lastly will this system stop water coming up from the floor as well as coming in where wall meets floor?

I plan on having this done very quicky and am trying to learn what is good and what is not good to do.I have got a few estimates ranging from 2k to 15k. Any help is greatly appreciated.

You asked..."Does water really come in as a result as hydrostatic preasure or is it more of a high water table problem??"

One is the result of the other. Hydrostatic pressure against a foundation is the result of high ground water. A foundation is like a boat. It wants to float on the water. You'd be surprised at the bouyancy of many an underground object when the groundwater gets high.

Groundwater is usually a periodic condition. Sometimes it's high, sometimes it's hard to find. Ask anyone with a sump pump. It can be silent for months, and then pump almost continuously.

When high groundwater is a perennial problem, usually, interior fixes are temporary fixes at best. Installing what some call a French drain in the basement can be almost the same thing as drilling a hole in the bottom of a sinking boat, hoping to let the water out. It provides a better way for the water to get in, even if it is more controlled.

The best measures against high groundwater and water in the basement are those that can be accomplished outside the house and foundation. Perimeter drains at both the footing elevation and halfway between there and grade can gather the groundwater "before" it begins to press on the foundation with nowhere else to go but through, or under, up, and in. Of course, there needs to be a place where these perimeter drains can dump the water, away from and downhill (downstream) from the house.

If you're heading towards that kind of solution, and will have the foundation exposed anyway, then cleaning the foundation wall and having waterproofing installed (painted, sprayed, or membrane) can be done at the same time.

Now, if your house is in a hole, with nowhere to drain the water to by gravity, you may be looking at an expensive exterior system with pumps. In that case, perhaps you'd be better looking at the ol' sump pump and sump pit arrangement where at leat you'll know where the water in the basement is.
