Leaking water thru geothermal pipe sleeves

I had a closed loop geothermal system installed 2 years ago and there is water leaking in basement thru the sleeves that my geothermal pipes enter basement below grade. Is there something someone knows that I can seal between the the pvc sleeve and the HDPE loop pipe to stop water from coming out of sleeve pipe.

Re: Leaking water thru geothermal pipe sleeves

For gaps like these you can use any of the following, depending on your particular need:

1. epoxy sealant. 2. hydraulic cement. 3. caulk and foam sealant.

They all require good prep, cleaning around the opening and the area must be dry.
