Tools for drilling through concrete/asphalt (3m depth)

[PRathor]

Hi I was wondering if anyone has advice on collecting soil samples at least 3m deep , through rocks/concrete/asphalt. I need something gas powered and portable. We already used the AMS core soil sampler but we hit really hard ground and couldn't sample deeper. Thanks

Do you have access to a drill rig?

Do you need a full size drill rig or a portable rig?

Shaw Backpack Drill is a portable rig that can drill through concrete and asphalt with ease.
