Apologies - no destruction video (yet). Anyone got opinions if there's any danger of a concrete pillar getting pulled over by a slackline? Pillar has a square cross-section, approx 1ft x 1ft; I'd want to attach about 1ft off the ground.

Fine at that height.

Reinforced concrete? What's it formed on?

How do I check?

It's on the edge of a swimming pool, supporting a roof.

Cut it in half!

Got a picture? Sounds like it's supporting a roof so would probably be reinforced.

I wouldn't like to say it'd be ok, but I'd probably do it myself. Just be aware of the consequences if it fails!

Number one, is what I'm guessing your trying to avoid?

If it looks sound (i.e. is not rotting or cracked), then I'd use it. If it was free standing, I'd hesitate but with the added info that it is supporting a roof, you have a large compressive load applied to it, so your slack-line is not likely to cause any tensile stress.

Thanks for the replies. The opposite end was to be a free-standing concrete 'ornament', with a circular cross-section and diameter about 2 feet. Having watched the video, I decided to find some trees instead!
