I agree with the steel. We have roofing contractors and barn builders here that will sell their scraps really cheap. (Some will give it away)If they're not all the same color, paint them or pile rocks up in front of the metal. If you are a DIY and haven't dealt with the sheets of metal, they are easy. You can cut in crosswise about 6 inches or so, put your foot on it beside the cut and tear it on across. I can take a 16 ft piece and have it in 4- 4 ft pieces in less than 5 minutes.

I personally want something to keep critters out as well as stop the cold wind.
Plan to spread borax under the house as well to discourage bugs.
Railroad ties would be a haven for a vast variety of vermin. I hate to think of how many snakes would love to live in them. I like the footer idea with textured concrete blocks.Cornhusker said:I've seen people use railroad ties, but I don't know how well they work.
I think the mobile home may hae been sitting right on the ties.
