I moved in to my home 6 mos. ago and am now looking at readying my unfinished basement to use for woodworking. I've never had a basement before, but there is a drainage channel about 1" - 1 1/2" wide that runs around the perimeter of the floor and leads to a well in a corner of the floor with a sump pump. These channels seem to have water in them most of the time but have never overflowed despite heavy rains. There are no signs of water leaks on the walls. I am concerned about getting sawdust, etc. in them and would like to protect them or seal them off in some way if this is feasible. I am also worried about mold and would like to close these channels off from the work area, but I imagine the design is this way for a reason. Any recommendations for dealing with this? Thanks.

The channel around your basement is an interior pressure relief drain. It is designed to keep water pressure from building up on the exterior of the wall.
I don't know why a channel drain was used but I suspect that the contractor that installed the system used that method to keep any wall seepage from getting onto the floor.

Sawdust will cause problems with the system. By its very nature it will cake up and cause dams in the system. It will also shorten the life of your pump.

I would not cut off acces to the system in any permanent way, but it would be okay to tape over it or lay some linoluem scraps over it to keep out debris.

If you have anyone that can break some metal strips into a "U" shape that you can insert or take out at will would be the optimum answer.

Hope this helps,
