Laying Loam/Growing Grass

[BrianS]

This weekend I am putting freinds and family to hard labor.

I have a side yard that has some weird holes and only marginally has grass on it...

SO.. I ordered 5 yards of loam to be dumped down so I can smooth things out and hopefully grow a little grass...

My question is this.. There IS some grass there... If I am laying down 2 inches of loam, will new grass seed take in this? will the grass and root system below be a problem?

If new seed ISNT a problem, should I lay anything down with it like turf builder?

I dont have access to a rototiller, and the idea of turning it with a shovel isnt thrilling...
