Stop tree roots in sewer
Bought because my neighbour’s tree had got into the shared sewage pipe. I read the reviews and it was highly recommended. So far so good and this spring will show if it needs to be done every two years or longer.

Successful after a long wait.
A gully at the side of the house was blocked by a mass of thin roots from our Hydrangea petiolaris. I cleared manually those visible in the drain but beyond the trap it was blocked and letting only a very slow trickle of rainwater pass. Since I was unable to reach the roots I used 5 treatments of the Roebic root killer; finally after 4 weeks I was able today to empty 4 gallons of water from a can directly into the drain without the drain overflowing. So , although I cannot see beyond the trap of the gully, the problem has been solved, thankfully.

Done the trick, amazed!
Had tree root ingress shown by drain CCTV. Was quoted a thousand quid to remove it! Tried this stuff, and it’s sorted! How do I know?We’ve lived with it in an old house for months. The toilet would block up as loo roll would catch on the tree root and back up. It would never clear itself and would have to jet it with a pressure washer to free it up.Since using this has been a few days of use and it cleared.

Foaming Root Killer
I have had a recurring root problem with my drains for many years which needed attention to clear blockages about once per month. But since applying this product direct into the drain via the manhole, the drain has been root free and clear of blockages for about three months and no sign of the problems returning at least for now. I am very pleased with the result.

Did not work for me
Seen reviews on this type of product and they seem to be good but after using it myself it had little to no affect and the roots where still visible after I used it not much foaming really

Foams a lot
Certainly foams! Only time will tell if it kills of the roots in my slow running drain.

arrived solid rather than powder got money back
Had to return and get money back as they had all solidified in the container and hence not useable

Customer service was outstanding when I had questions about the product.
Keep out of reach of children. Avoid contact with skin and eyes. For severe recurring root problems, use monthly or as often as needed. This product destroys roots in a home's sewer lines.
