I bought a house 7 months ago (in Minnesota) that I knew had water problems in the block wall basement. It has gutters which I have cleaned out since occupying the house, although with heavy rains water still trickles in on all sides of the basement, usually where the wall meets the floor but in some places a couple blocks up the wall. The landscaping around the foundation slopes away from the house for the recommended slope and distance and the douwnspouts are carried away from the house adequately. I'd like to get something done now so that this spring and summer I can test to see if it handles heavy rains and then I can plan on finishing off the basement next year.

I've had some estimates done for sub floor drain systems (which I've seen in this bulletin board possibly referred to as french drains?) done and they are asking for around 4,000. In the most recent "Family Handyman" magazine there is an article on how to do this yourself. I am considering this possibility as I figure I can save at least 3,000. The article however is fairly basic being only 1 page in length. I have some additional questions I would like cleared up before embarking on this project.

1. Does drain tile have to slope towards the sump pump? or is it standard to have it level all the way around?

2. What do I do about pipes embedded in the floor? My assumption is that I just stay away from them with the jackhammer and if I need to get closer use a maul and masonry chisel. In regards to question 1. If I have to go under the pipes with the tile it would negate any slope towards the sump pump.

3. At a recent home show one of the exhibitors said that these systems have a tendency to get backed up because the tile gets silted up and blocked. Is there any way to prevent this during the installation or will I have to have the tile checked and cleaned out periodically?

4. What type of concrete do I use? Is it feasible to rent a mixer and do it myself (60 cubic feet)?

5. Is it acceptable to run the pump discharge pipe about ten feet in the basement before outleing it ouside? (I want to oulet on the other side of some concrete steps where I think it will be less noticeable and can safely run away from the house)

Any additional information, suggestions, or helpful hints would be greatly appreciated.

Regarding keeping silt out of the drains- they sell special filters which go around the outside of the pipes.

Yes, you do have to slope it towards the sump. The water won't go anywhere if it's kept level.

Thanks alot for the advice. I really appreciate it!

I thought of another question.

I am a little concerned that when I am trying to break out the cement floor (18 inches around the whole perimeter of the basement) that I might damage the blocks. I don't think I would be able to use a jackhammer right against the wall and if I have to pry a piece out it may damage the block wall. Any suggestions?
