Help Needed: Basement Water Problem

[jibsey]

OK I need a plumber experienced in permanent basement floor submersible sump pumps and to hopefully pipe it outside, for the Farmington Valley, or Bristol area. For 40 years no water and now we have it in an unfinished basement. Currently getting it out with small pumps and garden hoses but that won’t work permanently and in extreme cold. Can’t go into septic drainage. I wanted to wait till March but don’t think I can. Any names are very appreciated.

Just put a 2.5 - 3 ft deep sump in the basement floor, that will take the pressure off the slab and it will gradually dry out. Don’t get the ball/float setup, it’s crap, get a good Little Giant submersible pump with a bronze housing and diaphragm switch. 1/3 hp with 18ft of head should be enough. You will have to rig up a 1 1/2 in plastic pipe 100 feet or so out into your property area that has the most down slope from your foundation. That’s the cheapest way to do it. A French drain will cost you thousands.

Thanks.

My only experience was an industrial application involving a leak in a tunnel. The “grout“ wasn’t a mortar type grout, but rather a chemical grout. When injected it looked like, and seemed to have the viscosity of honey, after combining with water and curing it looked like yellowish foam.

I was impressed with the results, and figure something similar would work for a basement.

maybe something like this , if jibsey wants to experiment a little before incurring a big expense. Looks like would be better for a crack along the wall rather than at the floor/wall junction though, and if the basement is hollow block rather than solid concrete it may not work well either. But the basement HAS been dry for 40 years so if this was me I’d try some minimal remediation before going in big.

@jibsey it’s rained a lot lately, but it’s also rained a lot several times in the last 40 years and no problems till now. What changed? Upstream local development/paving causing more run off? (If so see the town engineer) Long shot, do you have a clogged roof downspout/gutter that is causing water to overtop the gutter where it should’t?

The way you just described the “grout” injection is exactly what the stuff and
process looked like here yes a yellowish foam that dries when cured.

I had good luck with Larry Janesky’s Basement Systems. Triple Sump Pump which has a main pump, an overflow pump that kicks in when first pump gets overwhelmed, and a third that runs on a marine battery if you lose power.

I don’t wish basement issues on my worst enemy, the triple system gave me some peace of mind.

The sump should be corrugated and around 18in or 20in across with 4 or 5 inches of crushed gravel on the bottom.
