Flood control recommendations?

Chicago, Ill suburb

First off, I currently have no sump pump, only a cleanout installed and use a stand pipe if needed.

We have had 2 minor floods in our basement (due to our lines clogged with tree roots) we corrected the problem by installing a cleanout and replacing the pipe where the tree roots were forming.

In the last 9 months, we have twice had backups due to excessive rain where the city sewers could not handle the rain.

With these 2 backups, besides the water coming up the floor drain, water appeared to enter from all sides of the basement (filled up quickly to about 2-4 inches). Other than these incidents, seepage has been little to none where I can usually find a cause like clogged gutter overflowing and water seeping through windows rather than foundation.

We are planning on having overhead sewers put in with an ejector pit/pump insalled.

That being said, what's the recommendation on having floor drain tiles installed? - Quite costly and we have DIY shelving (2x12 boards on milk crates) on most perimeter walls. Would be a monumental task to move all this stuff.

We plan to once again carpet with carpet tiles. What's the risk of getting a basement full of water or substantial seepage?

Alternatuively would a backflow system be a better solution compared to the overhead sewer?

Thoughts or comments??


Re: Flood control recommendations?

Well your of defense against flood would be a sump pump, preferably one with a a battery operated backup as well. The perimeter drain tile would collect all the water in and around the basement, and the pump would get it out of the basement discharge it as far away from the house as possible.

You will definitely need to remove the shelving if it is in the way of where the drain tile is to be installed, but depending on the kind of shelves you have in place, you might need to just remove the bottom part.

I've seen drain tiles installed in dry walled basement and they only remove a portion of the bottom to access the corner.

Now depending on what you are going to do with the basement, you might want to consider something like the ThermalDry carpet tiles instead or regular carpet tiles.

They are floating, interlocking tiles that go straight over the slab, no need for padding or sub-floor. And since they are specifically designed for basements, they are 100% waterproof. If your basement ever floods, they will not get ruined or grow mold. You take them off, dry them out and put them back.

They also offer thermal protection. The finished surface is raised from the slab by a channel system that allows the slab to breath, and for that reason the finished surface is usually 10 degrees warmer than the slab underneath.
