man cave build...but 1st we need to fix seeping foundation

[Devaji]

so I got the go ahead to take over the basement for a man cave/fish basement . playing around with a DIY plywood build something 800 gal + leaning towards 1000 gal.

BUT 1st I need to fix the seep coming in from the foundation.
I live in Idaho so pretty dry 1st few years of having the house no issue.

we had a concrete patio poured and replaced the widow before it was just plywood covering a broken window... yeah I know any the last few months since spring we have been getting some seepage where the foundation wall meets the floor.

other than digging up our new patio ( very expensive in my area ) and adding a french drain.
anyone have was to fix this.
the basement smells wet and musty...yuck

here is a video outside of the basement:


here is inside where the issue is:


I am guessing when the patio was poured the rouge was not packed and a channel of water is going to the foundation wall?
or all the water from the patio is getting sucked in my the wall. it was sealed and slowed away from the house.

options. yes I have thought about gutters but we live in a very heavy snow area. I doubt they would make it past one winter. lots of snow and ice melt will rib them right off.

apply a rubber coat to inside foundation wall.

I am talking to some concrete guys but wanted feedback from the fine folks here on R2R hoping there is a cheap and easy fix so I can build out the basement this winter.

So is it leaking in through the window or where the patio meets the foundation?

Also in Idaho, North Central, and I have gutters. Definitely can be instances where ice builds and gets jammed in, but even my really old gutters stay in place. Perhaps you can also install whichever heated product they sell for roofs to prevent ice/snow buildup just to ensure this specific spot would stay clear.

My thoughts, and I'm no expert, just a fellow homeowner who's lived in a few old houses with "quirks", I'd prevent water as much as I could here, with gutters, maybe buy or construct a shield cover on the window, maybe even something to catch and direct the water away into the lawn. Think like a rain chain, with a collection drain rock and piping? Maybe disguise as a rectangle planter box?

LOL, you underestimate gutters. I am in Lake effect snowbelt in MI, routinely have to rake 2 feet of packed snow off roof over gutters, have done so for years without any gutter issues. When I say years I mean like my grandparents built the house in 57 with gutters, raked the roof, my mom bought the house, same gutters, raked the roof, I bought the house and replaced the gutters just as PM with gutter guards as trees were a lot bigger than in 57, and never had a gutter issue. I'd have to look long and hard to find a house without gutters around me. Your options to me would be install a channel drain in the patio, which would require cutting concrete, or put gutters on to divert all that sq. footage of roof water away from the problem area. With a proper slope, which you said you have, the gutters should mostly eliminate your issue. Not to mention that's an inexpensive option that requires little effort.

it seep in from where the wall meets the floor.

I did have that window replaced 1st time it leaked contractor did not call me back weeks later had another guy "fix" it. so it does not leak now.
that said they did not apply any water proofing to cement around windows. bitchathane is what they call it around here. maybe that is only for framed in windows IDK

I have looked it to gutters even had a guy out from the next town over 90 miles he also thought gutters would help. never called me back after we told him we where very interested .

you mush have some magical gutters out there. very few people can use them out here. I do have a metal roof so when it slides a ton comes off.
I'll look more in to gutters.

that said it has not rain here in quite a while water still seeping in not sure if that from residual water or what. but when it does pour its worse for sure.

any recommendation on heavy duty winter proof gutters?
I have heat tape on the roof but the snow pulls it down every winter. that the black stuff hanging off the roof.

anyone else have thoughts on this.

Here is the space I have to work with. It’s 33’ long by 14’ wide at the wider spots and 10’ and narrow spots. So not the biggest or the best layout but could work.

Looks solid! Should be a neat build! Will be following along

If the water is seeping into your foundation from the Patio, whoever formed and poured the concrete for your patio did not add a 1% fall away from the house like they should have. That 1% along with rubberseal would have helped prevent water in the basement. As stated above, install gutters on that part of your roof and rake the snow/ice if you have too.

A drastic option is installing Drain Tile (plastic vented pipe encased in pea-gravel) around your foundation or under your basement floor with a sump pump to remove excess ground water. After watching the video of your basement, I think you should strongly consider this option. The concrete on the end of your wall looks rotted, if you can chip it out with a screw driver it's in bad shape. So this might be the lesser of all evils, you get the drain and new concrete you know is level for your build. I live in the midwest, in reclaimed swamp ground of all places right by the Missouri River, I have a drain tile system outside my foundation, with a sump in my basement. They do work.

yeah I was very adamant about have the slop away from the house they said thay did and even asked again during the construction.
I think there is just to much water spilling on it even if there was.is a 1% slope away.

talking to a few gutter people that will be the 1st step.

the foundation looks sold but the paint is pealing off so that is a sigh that water made it into the the foundation.

thinking about rubber sealing the outside of the foundation as well.

not apposed to a system like that. already have a sump pump down there for a muck sink. so could tie in to that. IDK sounds very expensive but that might be the 3rd steep.
