I plan on getting the sodium bentonite, mixing it according to their instructions and maybe even renting a Vibratory Plate Compactor to make sure I get a good seal. I want to thank everyone for the wonderful help!

Could someone fluent in Pond speak please translate this for me: "I'd put a mess of bentonite in the possibly get it into the tracks." \:\)
