First time posting here or on ay type of forum of this kind. Thanks in advance for any advice. My wife and I purchased our first home this year in the northeast portion of the states, New England. The house was a flip job and in pretty rough shape before it was flipped. We’ve been there about 6 months and long story short our basement takes on water.
The house was built in 1940 and has a concrete block foundation. We believe the guy who flipped/sold it to us poured a new concrete floor less than 16 months ago, give or take. Unsure if it was dirt before or if he poured new concrete over old concrete. Also unsure if there are footers or not and the overall topography of the house is lower than it should be so we have a few issues at hand but overall I believe they’re all manageable.
So weve had 3 different estimates from basememt waterproofing companies with a pretty broad range of prices and recommendations. One company recomended a full french drain perimiter system, pump, the whole 9 for about 8k. The 2nd one was a sump pump with a small section of trench at the main entry point of the water (not an entire perimeter system) for about 4k. The 3rd one was just a sump pump with an outlet into a buried pot outside the house (away from septic obviously) for about 2k.
I will ad that recently we have noticed a hairlike crack in the basement floor which was not there before and it does bring water into the basement through said crack. Before the crack the only way the water came in was through the block walls, they look as though they’re crying. From the walls, once the water starts to come in it comes in pretty quickly unless its a slow rain then it takes some time. Now that the crack in the floor has appeared it only comes in through the floor (so far) and it comes in alot slower, slow enough that a dehumidifier will dry it after about 12hrs and it hasn’t come in through the walls since the crack showed up (yet). Could this crack be nornal concrete settling? I know it takes a long time to fully cure and its less than 2 years old as far as we know. Did the crack in the floor relieve pressure off the wall?
The company who gave us the 2k estimate to me, seemeed the best. Obviously the 2k price point is appealing BUT my wife and I don’t intend to live here forever and we just want a solution to remove the water once it comes in. We don’t want to stop it all together because we know that’s very unrealistic and probably impossible, we don’t want to spend thousands on a full perimeter system as we don’t really think its necessary. Also I don’t want to go digging too too much and possibly compromise anything as I don’t know about footings being in place or not. All 3 companies said they would check for a footing as well. The soil here is clay, allll clay.
Does letting the water enter as it probably has for YEARS then pumping it out pose any serious issues? Its not a finished basement, it doesn’t ever need to be and we dont care about looks.
Also Ive thought did pouring the floor actually cause this? Maybe it stopped some type of natural drainage which is why it comes in so fast through the walls now? And now that the floor is cracked did that alleviate the pressure?
This is a long winded post and I very much appreciate any responses and answer’s. Were going to have a job done soon Im just looking for input from different sources.
