    I do mostly lawncare, not really landscaping. But occasionally have to repair, or establlish new grass in small areas. Hauling loam in my pickup is a pain. What about the 40 lb. bags of topsoil? ($1.47 at Home depot). Would a 2 -3 inch covering be a suitable grass growing medium? Or is there not enough actual loam in it?
    Thanks for help.

    All that stuff is is swamp muck. If it is a small area use potting mix.

    But I would try and ammend and till like mentioned. The existing must be scarified anyways, may as well till.

    How many inches of topsoil do yo uneed that is sufficient for the grass / new sod?

    3" inches of new topsoil and then you lay new sod.. is 3" sufficient or do you need more so that it doesnt cause much draininage problems

    whenever i do a sod repair job i don't worry too much about what type of soil i am using... sod is pretty hardy and will grow on just about anything,, (literly)

    i actually put sod to the test last summer, i had a couple extra rolls from a job i was doing so i decided to see if would grow on my concrete patio. it did. i actually cut it a few times and was greener than most of my competitors lawns..

    what a selling point " we can grow grass on concrete "

    Till the soil. Add seed. Add fertilizer. Cover with straw. Add water.

    Most so called topsoil is nothing but scrap mixed with sand,scrap mulch,stone,etc.
    The depot stuff turns pretty crusty in a hurry.
