Sounds like the cracks have not been sealed well or the odor is coming from the concrete itself. Either way, our GBS Penetrating concrete sealer will help seal the concrete floors and walls. This assumes the concrete is porous, i.e. absorbs water, clean, dry and has not been previously sealed or painted. For the large cracks our M-1 is the best sealant for this purpose.The AFM Polyureseal BP will not seal mildew or dirt odors, only VOC odors.
