Answer: I think I would investigate a little further. You can fill with topsoil but you'll want to determine just why the sunken areas are appearing near the foundation of your home. If it is new construction it could just indicate settling of the soil. If your home is a few years old, it could indicate poor drainage, in which case you might want to install a curtain drain to help redirect rainwater. Best wishes with your landscape!
