HI guys!

Does anyone have any experience with these?
erkat | fields of use: Demolition, Refurbishment

I have put a bid on remowing a thin layer (12mm/½") of bitumen that has PAH in it.
It has been working as a water seal on a concrete floor, above the bitumen there is polyurethane blocks that are easy to remove.

But the question is, would a Drum cutter be a effective tool for removing this thin and sticky layer of PAH contaminated pitc, so i can get a rough clean concrete surface.

The base machine would be a BROKK 180 demolition robot, i have seen surface cutters on skid steers as well, but the robot is a lot better in tight places.

how big is the wear on the teeth on a drum cutter?

on the Erkat site they show a video when they demolish a old german bunker with a drum cutter, they say it cuts up to 40mm reinforcement rods
