Base for Rad 1 curves

[Wet Woking Neil]

Before I start hacking up bits of wood, is there anything that is the ideal track base l for rad 1 curves and or other radii curves. Initial thought is series of small plywood blocks maybe 2' x 1' with potential 20-30° wedge ends. Alternative maybe an open PVC frame. Or is there non wood Alternatives? Any suggestions/recommendations appreciated.
Thanks

On the ground or elevated?

Elevated, ideally around waist height, although not decided how yet. Plan was on breeze blocks to allow change with initial setup, but housing manager (wife) has banned them.
