Horrible smell from rear of toilet

[Compo37]

Moved into an old council house and I think the toilet soil pipe is leaking I fitted a new pipe but we still have the same smelly problem. I noticed that waste appears to be coming back behind the toilet soil pipe , should I use rods to clear any possible problem? Or use concrete to fill around the pipe and seal it? Or is there an extension that fits inside the soil pipe that would put waste further down the pipe? Any help appreciated. Many thanks

Hello. A photograph would help, as it's hard to imagine it.
Your joint should have been a tight seal. Perhaps you have put a toilet pan connector designed for pushing inside a 4" pipe & you have put it into a joint in the cast iron or clay soil pipe?
To seal that you normally need to use a small piece of 4" pipe & seal it

The concrete at the rear of the soil pipe was broken obviously I didn't repair the concrete well enough to perform an airtight seal and the waste is somehow back filling up the pipe and out around the soil pipe, probably best to repair my concreting to seal the hole.

Concreting is probably not the best solution.

There are many available 'off the shelf' products that could solve your issue once and for all.
It's just a matter of knowing what is available and what best suits the repair that you require.

You could end up spending more money trying to repair it yourself than the cost of getting a Plumber in to do the repairs

I would get a plumber in for piece of mind more than anything. They can give it the once over and make sure the job is repaired properly once and for all.
