    I've been pricing some fill for a lawn restoration. I've been finding huge variations in what suppliers are using for fill. Most are using a heavy sand base screened down to 1/2. Others are using a sand silt mix. I need to add good topsoil over the fill so I'm concerned about too much sand.
    I was going to add fill then mix with topsoil but this idea isn't going to be any good with sand right?

    The current soil composition is clay and decomposed granite. I've done soil test and need to add about 1200lbs of lime. So I was going to add the lime then harley rake it in then add the topsoil. Is there some other name for fill that I'm missing here?

    For structural fills, we use "gravel borrow" or what some guys like to call pit or bank run. The gravel borrow sounds like what you're describing; sandy material with round rock in it, ours is typically screened only to about 2-3". For what we do with it, the more rock that's in it, the better.

    I use what is call common borrow. All it is, is fill contractors have removed from work sites when digging for fondations or whatever that isn't worth anything for screening. Usually sand/ clay, rock mixture at the pit I take from. We have seen loads that are different everytime. Doesn't matter what you fill with as long as it gets packed down then add 3-4" of loam and youll have a nice lawn.

    are you looking for a fill soil or aggregate based fill?

    Well, I like the drainage properties of the sand but want to ensure long term lawn results.

    If you're going to cover the fill with topsoil, go for the sandy stuff.

    agreed, the lower to mid grade stuff is made by mixing local soils with foundry sand, the higher end you go the less sand and more compost thats in it. you'll get more clumping but a better ammendment.

    what i do for lawns is harley rake in the mid grade stuff and either top it off with our pro blend or a technagro compost blend depending on their budget.

    Go with the common turf blend 50/50

    50 percent washed sand 50 percent top soil.

    The ground can retain dampness and the sand keeps the grass roots cool in the summer.
    But it drains and doesn't puddle up in the winter.


    Trust me the stuff is the way to go. We get ALOT of rain here

    I called around a few places today for try and find a mix but everyone's selling sand heavy products. I'm going to lay at least 3-4" of a real good topsoil/compost mix so I'm thinking I should be good. Should I harley rake the soil then add the fill,rake again the add the topsoil/compost? I was planning on rolling lightly and seeding heavy , then rolling with the roller empty. I was banking on over seeding in the fall to get that thick lawn the customer's after.
