Strength of flexi land drainage pipe - Drainage unde patio

[art davidson]

Hi Gents,

I will be building a patio and decking area next to the house, garden slopes towards house. I have a land drain 7m from the house and plan to have patio falls etc towards drain. I was thinking of running some flexi pipe from decking (glorified pallet) under the patio? Would flexi pipe withstand pressure from hardcore and whacker plate etc or would it collapse?

Kind Regards
