Sandbag construction

[Troy Archie]

I'm making a sandbag and am curious if putting wet sand into the zip-lock baggies is a bad idea...
It's winter and dry sand is a rare commodity and it just doesn't seem to want to dry out even in the house.

My first idea is that it may create mold problems so dry would definitely be better. How about the oven, dry out say 5 lbs at a time? Another thought, your local building supply should have dry sand in the masonry section.

Pulverized limestone from Home Depot runs about $4 per 50 lb. bag. Dry and cheap.

I've filled sand bags with both of the following: 5# zip-lock bags of rock salt (the kind used for water softeners), "playground gravel". You can buy either at most big-box hardware stores. Both work well.

I found gravel works best so far. Has a better feel.

Just go buy it. I think I got 100#s at Home Depot for like $6. Section it out into 5lb Ziplocs, double bagged, with the opening duct taped. That makes it difficult to leak and makes the bag adjustable.
