Ensuring a lawn doesn't heave

[DragonflyGardening]

I'm replacing a lawn for a couple who have a lot of weeds, perhaps some slugs, and a lot of heaving. I just was looking for any tips for making sure the new lawn doesn't heave again in a few years.

Basic process I'm looking at:

Sod cutter
Till so that it can be levelled
Add a bit of compost/topsoil - level
Roll
Sod

Any tips or tricks I should be thinking about?

There are no tip's or trick's to stop frost heave's that i know of.

Anything that holds moisture will heave. Sandy soil will move much less if at all.
