About a month ago I had an internal french drain / sump pump system installed along the back wall of the house. It has been raining here for 24 straight hours and the new system is working well. Problem is that I did not have them extend the system along the side wall of the garage, which is now leaking quite a bit of water into the garage. Company's best offer is $500 to extend the drain for this 17 feet or so, and run it into the pump. I am seriously considering doing this work myself (I realize it is backbreaking work, but $500 is $500). I would like to try and match up with their system though - and they installed an "egg crate" type piece of plastic that sticks up maybe 3 or 4 inches from the floor along the base of the wall (with some holes of course drilled in the blocks behind the plastic - then water then goes down into the drain). Supply places that I call say this is "drainboard" and only comes in 4 foot by 150 foot rolls for $150. All I need is a piece 17 feet long by 12 or 18 inches. Does anyone know where I can get a smaller quantity of this stuff?

I'd to like to put sheetrock in front of conrete basement walls (only up 4 feet). I'd rather use furring strips instead of 2x4 framing because this particular room is small. What size furing strips are recommended and also what size sheetrock screws? In this room there is currently 1950's paneling attached to 1" furring strips.
