Reclaimed plywood sheets

[lettywetty]

Hi,

I bought an old house and need to clear the garden which is full of old concrete base and slabs.
I plan to hire a grab lorry as I was told it would be the cheapest.
I am looking to get some plywood sheets to protect the floor under the rubble. I am very annoyed to buy new boards for that, where could I get some old used ones for cheap in my area, I live in Woking, Surrey.

Thanks.

Letty
