What size jack-hammer?

I don't think hedge roots would be too bothered if the strip was left in.

Hilti TE2000 - https://www.hilti.co.uk/c/CLS_POWER...25/r6025050?activeTab=preconfigured-kits-tabs - excellent machine, will go through it at a reasonable rate

Hilti TE3000 - https://www.hilti.co.uk/c/CLS_POWER...5/r11668382?activeTab=preconfigured-kits-tabs - the best option, but it weighs 30KG so exhausting. It's a slower impacting machine, with loads of power. If you have the strength, it will be quicker.

Hire one for the day, or the weekend so you can take more breaks. I hate breaking foundations up.

My wife (quite the horticulturalist) seems to think that the would good down deeper than the concrete so would be impeded.

The roots will go around the strip, they will find their own way.

No good arguing with the ultimate authority: get breaking.

It's probably 20-1 concrete mixed with mud and stones - what've got in your shed? Decent SDS, pickaxe, sledge hammer etc, find the heftiest thing and give it a try. If you get nowhere then work up. When we subbed for a tarmac contractor we would start with his power pack and then hire a big Ingersoll rand on a trailer - if that didn't work the job was too big for us. We once did a floor in a school classroom - over a foot thick and they'd only allow us to use electric breakers - took us 3 weeks on day rate - I think my boss retired off that job.
