Caulking Slab/Foundation corner joint (Radon)
Hi we have an insulated basement slab that was notched where it joins the foundation wall on the top. It is supposed to be caulked/sealed at the notch where foundation wall and top of slab meet, to air-seal/radon-seal. What would be the proper sealant to use for this joint, around the interior perimeter of the basement?
thanks in advance!
