basement water issue
 
Im hoping someone could help me out with this....Couple of days back we had a very heavy rainfall, we have had problems with water in our basement due to the grading of our yard in comparison to our neighbours.We have built a french drain all across our backyard and around our garden bed to divert the rain water to the storm drain a few houses away. We just recently started after the big rain we had getting a small puddle of water coming up through the basement floor...when i looked in the floor drain i noticed that we have 3 inches of water in the drain. The closest outdoor gutter running into the ground is approx 12-14 feet away from the basement floor drain. Should i be concerned with the water underneath my house and what would cause that? There is a shower that was put in prior to us buying and im not sure if that was hooked up right? In the floor drain i just felt like dirt and gravel on under the water..Our house was built in the '70s. What precautions can i do? Is the city responsible for the proper hookup for that basement drain? Im hoping to get some answers ...Thanks

Water in that drain is most likely normal. My slab is a bit over a foot thick and when I look inside the sump pit, I sometimes see a few inches of water, which is slightly above the slab's thickness. There is a drain so any excess water goes in there.

As for the puddle that's a major issue, most likely a break in the wall's seal (tar paper I believe is what is normally used) which would require digging outside to fix properly.

As a temp fix, hydrolic cement might work if you can find the spot it's coming from.

uncontrolled water inside a home is always a concern to most whatever the source :yes: your backyard catch drain will be a help to surface water but, unfortunately, the underground pathways down to your footer are already established,,, think of your bsmt as a ship's hull below the waterline & the resolution's much easier to understand.

1st, positive drainage from the bsmt walls above grade & downspout leader drains should be in place,,, after that, your problem may be due to either a high water table OR a false water table in that the collected rain that runs down the bsmt wall is collecting at the footer thence under it & up thru crks in the floor OR the cove ( where wall meets foundation )


not being able to look thru floors myself :no: even tho we waterproof homes for a living, a sump & pump OR gravity drain's will usuall resolve the issue,,, doubtful the shower's a cause nor is the city responsible UNLESS the hookup was done incorrectly by a licensed contractor & approved by the city,,, in any event, i've never seen any govt agency admit to financial responsibility even if they made the error :wink:

precautions are noted above but, generally, the cure's a jackhammer, sump, & pump.

Hey, it's reallyconc, can you use a bigger font. I value your responses but I have a hard time reading them! Thanks

red, tar paper is above grade 'back in the day' - nowadays its housewrap.

hydraulic's like putting your finger in the dike,,, it might be better than a sharp stick in the eye but the water'll just show up somewhere else still in the bsmt :yes:

the font's #1 - smallest they have - i hate :censored: reading glasses while on the computer so sit back farther. gins ( or further - never remember the difference :no: )
