Re: wet basement
I firmly believe and agree with the other posters ...... the best approach to dealing with basement water issues in the is from the outside .... that's usually the main source of the moisture.
If the secondary inside approach of dealing with this issue is used then it needs be done properly.
It's scarey when you mention the contractor seems to be learning on your project ... and franky the comment above is scarey.
My contractor does not want to do this saying it will just increase the amount of water the pump will have to deal with.
The lower course of block is going to accumulate water if the foundation isn't water proofed along with proper drains on the exterior.
You definately need to relieve this water build up in those lower course of blocks by providing weep holes to the interior drain. If he's worried about too much water overwhelming the interior drain then you have big problems.
I believe the weep holes in the lower course of blocks along with the dimpled drainage membrane should be employed.
Here's a link to Platon one manufacturer of a dimpled memebrane along with a "where to buy" locator : http://www.systemplaton.com/foundations.html
