Killing big roots

It was lavender, a really well established bush. The 'tentacles' are woody and look dead but are alarmingly big, I am just worried about them going under next door's drive really and coming through somewhere there. DP has dug out about 4 really big stumps (the size of someones knee and lower leg) and these are the bits that he had to hack off to get them out.

what kind of tress were they? lots of roots dont grow back from when a tree is cut down if there is a stump left take all the bark off the stump and cover the stump with stump killer and then cover it with a black bag or something for a few weeks, it wont grow back. you can also drill big holes into the stump and fill them with stump killer.

This might be what you're thinking of.

We have root issues in our garden!
My mum tells me there is something that you can pour on that will kill the roots...why not ring your local garden centre and ask them? That's what I'm planning on doing! Good luck!

Please bear with me, I am a beginner grin This might be long...

We have a paved driveway with a sort up built up, edged bit that is meant for planting. When it was first done I grew lavender there with a lot of success but had a real problem with brambles coming through, presumably from old roots buried deep, as I didn't see any when I dug the ground to do the planting. Something odd happened last year when a big scorched 'hole' appeared in the lavender, which we think was caused by a rogue cigarette from someone walking past but it damaged about half so we decided to cut it down and start again. We were having a tree lopped so the guy cut it all down at the same time leaving some fairly big roots. We have been digging it out but the roots are enormous under the ground and the 'tendrils' and go under next door's driveway.

Most of them look dead and DP has taken out the big bits but we are worried they are going to regrow or erupt through next door's concrete. Is there anything we can pour or paint onto them to kill them dead? I am not worried about tainting our soil as we are going to put slate chips down and have big square planters with something in them rather than a bush type thing. I have just been googling caustic soda so I did consider Oven Pride! Any advice would be great.
