I purchased our home in 2010 and it was built in 2006 near Tampa, FL. Over the past year the back room of our house gets a little water below the baseboard during really heavy rain over a period of time.
I have to use a carpet shampooer to pickup the water and it is quite a bit, and I have to empty the canister multiple times during fairly heavy rain events.
In trying to track down the issue, I called in a “Leak Detector” company and they told me that my grade was not an issue but there may be cracks in the slab/foundation wall meeting point.
I decided to dig further (no pun intended) and digged about a 1-2’ around the outside of the backroom. Here are some pics.
And on the inside:
You will notice a touch of mold on the carpet tack which i will replace. There has also been a few ants and dirt under the baseboard.
I powerwashed a little of the outside area to clean off the dirt, that is the water puddle shown. I also tried to see if i could make the water go inside, but i could not. I shined a light at night from the inside, could not see any light outside. So either these cracks are very fine or there is dirt in them.
I would like any advice on how to proceed. I will most likely do a french drain as i have a slope directly behind this area to a retention pond, but i would like to seal up outside as well. Should i have cement re-poured to fix the slab edges which appear to have eroded away? What should i use for waterproofing, a Seal-Krete Damplock like material, a bituminous sealer, etc…
Any thoughts would be incredibly helpful.
