Being one of those folks that are always looking for good quality at an inexpensive price leads me to ask the group about this method or related info concerning other inexpensive flooring options for a shop, hangar, garage, etc.

I've done a little research on the topic of "soil cement" and find it interesting as it seems to be a way to get a workable surface with good durability for a lot less cost than calling the guys with the big white truck. Here's one informative source for those interested:

A web search will bring up many videos on this subject.

One friend (with a beautiful Luscombe) used this method for his hangar floor and it seemed to be everything one could ask for at a greatly reduced cost.

Anyone here have any experience with soil cement or something similar? I'm about to begin the floor in my shop and thought this might be a good option to consider.

Appreciate any input ...

========================================

I really don't see that much Cost Savings. If you have to:

**"You will need about three to four pounds of Portland cement for each square foot of your soil cement surface. Use a bit less for soils with a lot of sand or gravel, and a bit more for soils with more clay or organic matter. Carefully scatter one bag of dry cement over the tilled surface, and then work the cement into the soil with your tiller."** You still need to Buy Wood for Forms. Once you Factor in maybe Renting some Tools, Bob Cat, Mixer, etc.

Where you may Save a little Money is maybe on the Sand, which is cheap by the Ton from any Quarry, and your Labor vs Hiring Someone, and Buying the Portland Cement in a Bag and Mixing it yourself. You can Buy Premixed Sand and Concrete where you just add Water.
