Question DetailsAsked on 7/15/2015

Who do I call for water coming up through concrete in my garage?

There is water coming in through what appear to be surface cracks in the concrete flooring of the garage (we have only been in our 50 year old house for a year and this started just about a month ago and seems to happen rain or shine). I am also concerned that there may be water under the flooring of our finished basement which is several feet higher than the garage (it is a split level house and the finished basement is about 5 steps up from the garage) since the floor seems to be bubbling in some locations. This could be due to a poor DIY job from the prior owner and I really don't want to rip up the flooring to find out. We have a pretty high water table and the house sits at the bottom of a downward slope (about 5-6 feet of what appears to be level ground prior to the house. We also have a well on the same side as the garage and a natural gas line that was installed last fall as well. I just want to know who an appropriate contractor would be - a plumber, waterproofer, etc.

Do you have the same question? Follow this Question

Definitely basement waterproofer. If leakage is in one area of garage dropping a sump pump in a crock with outside drain line might be the ticket. For whole garage or select area like parimeter that faces the uphill side of the buried garage floor, A drain tile in a river rock lining perhaps a fiber wraped drain tile as secondary filter of dirt.

In the old days we got about $30 a foot for break out of concrete and tile install and with 50ft pump was included in a sump pit with plastic cover similar to a garbage can with knock outs for water entry.

Firsst, I would turn off all water consumption, pump, and any circulating pumps and fans at furnace or boilers or such - then listen at nearby pipes to hear if you hear water flowing - could be a water pipe leak - rule that out before assuming it is groundwater, especially since you have been there a year and just started a month ago rain or shine - my initial guess would be a water pipe leak, either in house or in the line from the well.

You have to start listening as soon as the pump is turned off but before pressure drops off if it is a leak in pipes.

Other possibility - overfilled septic tank or leach field, or natural gas line intercepted sewer and caused a leak in it.

If not sure if it is high groundwater you could (after getting utility located) dig or auger a few holes on the uphill side of the house to see if you do have high groundwater level - will probably need a round bucket type posthill digger (can rent) with extension pipe to get down to below the bottom of the foundation level where the slab level is - and be careful about paying attention to digging behavior and sound in case there is a french drain down there that is not working. I would stay 3 feet or more outside the foundation to minimize risk of hitting that, though if in hard ground or bedrock you might have to dig right by the foundation to be able to do a hole. Since basement is higher start around it with shallower holes, then a deeper hole or two around the garage, though it may have shallower foundation and slab may be closer to ground level.

I would also do a static test on the well to house water line - put a pressure gage on line, pressure up with pump (and no uses on in house), then shut off shutoff valve at pump, turn off pump, and watch gage to see if it drops off - should show negligable drop in 5 -10 minutes - perhaps a psi or two as air bubbles redistribute but any true drop in pressure means water leaking out somewhere in the system. Then do again also shutting off the water line at the house shutoff valve, to determine if in house part or feed line to the house.
