Hard to understand your question.
Can you explain in more detail or post a picture?

We have a radon box under the sitting room floor and it was piped to outside.

We built on and the builders just poured a floor over the pipe.

If the vent pipe has been blocked then you need to get it sorted because the gas will continue to build up.

They poured a concrete floor over the vent pipe

Around the vent pipe?
The vent pipe should be buried in your sub floor build up.
Who is designing the extension and who is providing certification for the extension? Who is inspecting the works for Building Regulation and Planning compliance?

Over the pipe.

Don't ask, long story. I think we spoke before about it.

Has your extension not got a radon membrane and a radon sump?

He should not have covered the cap with a floor.
This must be left exposed for possible future use should you have radon issues.

Simpliest thing would have been to expose it back to the 90 and link to the radon sump in extension, then take this to outside, turn up and cap.

It might be possible to clean down around the cap and leave a way to vent. Have done in high security circumstances where exterior capping was not possible. But unusual and will require guidance from an experienced professional.

As above, who's the assigned certified? Who detailed the radon proofing to extension and tie in to existing. Sounds a bit dodgy.

Not necessarily. The cap is actually for future use and should be sealed externally to be used as a vent if required.

But you are right. It cant just be buried regardless.

We live in an old house, there was no radon barrier in the house but a radon box was installed under the floor and piped under the floor to outside.

We built an extension for disabled use and found out our builder is a cowboy. No radon barrier or box was put in extension.

Was it installed for a reason?
Generally a retro fit is due to high radon in the building.

In these circumstances it would be best to vent the sump though rather than cap as the sump does little/nothing when the outlet pipe is capped.

Unfortunately yes it seems you've encountered a "cowboy"

1. Is it finished and paid for? If so is much retention held?

2. Is it signed off? By who?

To answer your original question OP. It is neither allowed nor ok.

You'll have to remedy the situation somehow - either by installing a new pipe/pipework or somehow repairing the existing one. You should also sort out the radon protection of the extension.

You should also carry out a test for radon - usually this is done by leaving two little boxes in your house for six months - but there is no point doing this whilst building and remedial works are ongoing. I am aware of devices that advertise an instant measurement of radon but I have no idea if they are appropriate or accurate.

Yes paid. Signed off? It should be on an episode of cowboy builders.

You wouldn't believe me if i told you.

how can i sort protection of the extension?

Metric Tensor

It usually involves some sort of retrofitted ventilation system combined with floor remediation works.

However, it's only usually used when a radon problem is confirmed so testing is the first step.
