Revision history [back]
Hi Hannah,
My first thought re concrete versus pre moulded plastic is that concrete is widely available and can be made in small batches to suit purpose and for many purposes requiring a little knowledge and skill regarding mixing, proper placement, and curing. Pre moulded plastic is a specific skill with specific equipment and suppliers may be difficult to source or there could be delivery issues. Relative durability could also be an issue.
I speak as someone who has dealt with a lot of concrete and very little plastic so I could be biased! It would be good to hear from someone with more experience with plastic
