Keep all the good advice coming! I don't mind it one bit.
I'm sure I'm already on the builders "not friend" list, although he still calls me boss man anytime we talk. lol
There will be a secondary drain on the high side of the house that will divert water around to the lower side and exit 50' or so away through a underground pipe on the downhill side of the house.
All downspouts will be connected and run through a seperate underground pipe that will also exit 50' away from the house.
This is in addition to the already installed drain system along the outside perimeter of the basement walls, that also exist 50' away from the house. This system is tied into the floor drain in the center of the drain fields.
This should keep almost all water away from the house except maybe during extreme storms with high windows that will splash water directly on the walls of the house.
The Superior Wall product comes with a 10 year guarantee against any moisture/water issues, as long as it is installed as per their instuctions, which this house is.
All that said, I will ask the builder what he things about backfilling with river rocks and if he would charge me more for that. I really think that having those 3 independent drain systems will cover and prevent 99% of all water from ever reaching the basement walls in the first place.
