Forgot to also ask,

3. Concrete sand, is it same as sharp/builder sand?

Thanks.

Masonry sand is the one most talked about.

Personally I don't think it much matters. Sandy loam would work fine if there was no organic material in it. Organic material will ultimately disappear leaving the soil lower than you think.

I have the same question (live in DFW). I was also recommended sandy loam, and was told the masonry sand would wash away with a heavy rain.

1. Masonry and builders sand are the same thing. Any brick and/or lumber yard carry it. Sharp sand is similar but not the same thing.

You can use sandy loam if you wish, but as mentioned the organic material will decompose. It is best use to fill flower beds, gardens, or if building a new home to be brought in as your top soil with a 4 inch layer.

was told the masonry sand would wash away with a heavy rain.

Well yes if it is on a slope, but any material will do that.

"You can use sandy loam if you wish, but as mentioned the organic material will decompose"

That explains why the masonry sand quote I got was so much more than for sandy loam.

Thanks guys.
