There are several things you can do to make artificial grass stand up better:
At the initial installation, add more infills (2 lbs per square foot or more).
When you start noticing the turf to lay down, to brush or broom it on a warm day.
If it is not too late, when you choose your product, you should choose shorter and more stiff ones vs the long and soft version.
