There may be some sort of an epoxy like product that will penetrate and bind the existing material and provide a finish. Dampness though may be a problem and prevent the applicatin of any finish type of material.

Precisely. Especially in Alberta.
I would be tempted to trowel fresh concrete into the 'craters', then a thorough cleaning to remove all dust and dirt. Possibly a wash with muriatic acid, then an epoxy finish.
