Hi All,

Here is a picture of the issue: Imgur Link

Here is a video of issue:


We have a 4 Ton/2 Stage Vertical Flow ClimateMaster Tranquility 27 (Model # TTV049AGC01ALKS). It was new at the time of installation (Installed when we built our home - it is 6 years old right now). It is a closed loop, horizontal field. We live in the Greater Dayton area.

The reason I'm posting today, we have a horrible leak where the loop lines leave the foundation (see attached video and picture). There was a big snow melt off yesterday, as well as some significant rain and I'm sure the water table is high as heck in my area. I've captured and evacuated no less than 30 gallons of water since yesterday around noon.

My question, what is the best way to seal this? From the outside? From the inside? What methods (please list type of materials/procedure name please, as I am a non-educated foundation sealer/geo guy) are safe to use with the geo-thermal loop line? I am unsure if these would be sealed up in the same way as copper piping.

Finally, does anyone have any recommendations on who can do this in the Greater Dayton/Cincy area?

Thanks!

find some bentonite granules and pack them into the void surrounding the pipes. we have sealed many leaks this way

I'd investigate two solutions. 1) improve drainage in the area outside of the leak and 2) dig around the leak area and pack it with bentonite.

Awesome, thank you gentlemen for the help.

1) Can I do it while it is wet?
2) Where can I buy this stuff at? I'd rather get it from a local guy/gal. All I can find online is this -> https://www.amazon.com/Akshar-Chem-Bentonite-Granules-OZ/dp/B01N7AY5ID/ref=sr_1_2?ie=UTF8&qid=1482148268&sr=8-2&keywords=bentonite+granules
3) Is this stuff safe to handle with hands, or should I use some gloves?

Thanks again!

Yes, you can pack it in while the hole is wet. The bentonite takes a little while to absorb the water and swell.

I found granular bentonite at the local cattle feed store, but the smallest quantity available was 50#. I think I paid ~$12/bag for it. It is used locally for sealing ponds. I think it can also be used in cattle feed.

Bentonite = clay. It is safe. You can even ingest it. Many alternative health sites on the internet claim it detoxifies the intestines.

Awesome - thanks again to all three of you for the great help.
