My basement will sometimes flood when we get a lot of rain for several days. It's basically just enough to soak the carpet badly, but never gets over the carpet. The French drain on the outside of the foundation has been clogged for years. Due to having a shed and deck on the back of the house, digging it up isn't an option at this time. I probably won't live in this house for much longer anyway.

I am tired of hassling with drying carpet. I am ready to pull it all up and put down ceramic tile. At least I can use a squeege to move the water out then.

I suspect that the water may be building under the foundation and then rising up where it comes in between the floor and block wall, along the back side of the house. That said, I wonder if I should put tile on all the floor but about 1/2" along that back wall. Maybe it would act as a channel to hold water and move it to the end, where I can "drain" it out to level ground. This channel would then be hidden by a baseboard. Keep in mind that this is such a slow progression of water that I havn't located it yet, so it's not large amounts of water in a short period of time.

I have done some ceramic tile recently, on wood floors. I used Hardibacker for it, and it turned out great. Is it reccomended to use hardibacker on concrete floors? If I do as I mention above, will the backer board absorb moisture and buckle up like wood, or cause other problems? Would I just be best to tile all the way to the edges of the floor and hope that the water comes up on top of the tile, rather than seep under it?

In short, I plan to sell this house within 2 years, so I don't want to spend the $4000 that it would take to fix the drain as it really should be. Tile offers me a way to help control the problem, as well as increase the value of the property.

Any advice will be appreciated.

you do not need to use a backer board ... just latex modified mortar and the tile.

Be careful ... under law, you need to dsclose the water problems in taht basements to any prospective buyer and retail agents, under criminal and civil penalties for non-diclosure.

What I would do is make a trench with brick or small cinderblocks around the area perimeter, then coat them with penetrating sealers

then apply one or two a coat of Super Thoroseal Masonry Block Sealer to the brick or small cinder blocks.

This creates a trench for all water from the walls.

Then install the ceramic tile with latex modified mortar

Although you shudlnt use backer boards you can use a waterproofing, uncoupling, and vapor pressure equalization membrane such as schluter ditra



There are two ways to do any job. The right way and the wrong way. Do it right everytime.
