There are many alternatives although a personal favourite of mine is polystyrene ceiling tiles (obtainable from DIY stores like B&Q).

The tiles I have sit a little bit higher than the track but are easily sanded to the road height. Here the tiles have been finished off by painting brown/green followed by a scatter of static grass. The curb stones are made from cork sheet.

3mm hardboard is good for things like tree bases.

There is more information on My Webpage and the Members' Layouts in SlotForum resources are an invaluable source of inspiration.

Good to hear I inspired you with the borders Mark!

Here are a couple of moveable tree bases made using 3mm hardboard:

I just cut out some curvy shapes in hardboard, rounded the top edge with sandpaper, glued the trees on with PVA, painted the base and flocked it with model railway scatter.

Hope this helps.
