    Impermeable Layers for Best Management Practices

    I echo beej67, a Polyprop landfill liner would be best. Comes in large rolls and if joints are needed can be welded to form a continuous barrier.

    Can pin piles be driven into bedrock?

    You would not be able to drive a micropile into bedrock no. It would have to be drilled in and grouted.

    Piles driven into bedrock

    born2drill - Yes that is exactly the type of system I was talking about. I have seen the MAI bar used with a Tungsten Carbide bit (from the same source I believe) drilled using rotary percussive action into strong rock with success.

    Piles driven into bedrock

    Why not consider using hollow bar type systems to drill the hole with ? You can then grout simultaneously ensuring you have correct grout coverage and also correct location of the pile in the bedrock.
