Re: what's the best drainage system for a basement? is it even neces

[Guest guest]

Hi,

I am dealing with an interesting situation. My basement used to have water in

the center of no where in the spring, I put in french drain, and the water in

the middle went away. However, due to the Radon reading at 5, I later put in a

radon fan and covered the french drain with plastic covers ( by the radon

remediation company), seal the sump pumps last year. late December last year, I

had a flood in the bathroom upstairs due to toilet water line leak, the kitchen

below has water leaking through the ceiling. And, the center of the basment also

had some water. The french drain does not work now?? I had new 6 " gutters and

new front siding put in last summer. Regraded the outside somewhat. I did

noticed the rain was jumping out from the wrong end last Nov/Dec time.

Now, I had the gutter people reshaped the gutter, roofer replaced a pipe, fixed

the water line of the toilet. But, the french drain is not working any more?

Momoko,

If water is rare, it's not worth the expense. In my experience, most basement

water problems are due to improper dispersal of roof water. Spend some money on

subsurface dispersal of water to daylight. Make sure that all the grading is

correct.Purchase a Santa Fe dehumidifier. Clean the basement so that you can eat

off of any surface.
