I hope that your 2 ft retaining wall is at least full-brick (20+ cm), not half-brick.

Half-brick - as I suspected. Hopefully, the curvature will make it stronger and stable enough.

Thanks for this..I am having a slightly higher retaining wall and will ensure its two bricks wide.

They can fail as well. Just looked at maybe doing this one.

I was about to post that as I read through the thread. They've used brick that we used making our 16 inch square pillars years ago and I used the same pointing and got a similar result, nice look.

I'm not too sure re the double brick retainer as it's curved like op said and the land looks level in the pic at least and its
only a few bricks tall but drainage, would that be required but it would look odd.

OP - the conservatory people, are they registered with someone that you can turn to if things go wrong?

NB: I'm not a builder

Good luck

Also hope the air brick goes through cavity via some sort of channel… I have doubts especially as it was done after completion. How do I check ?

Is there only one? I would have expected them to be on the other wall and inline with ones already on the house. 

Yes one air brick. The one under the house is at right angles under the existing patio doors.
i have my doubts that there is a channel via the cavity into the inner leaf. Just trying to keep me happy I guess.
i know nothing about building,seriously,yet even I can see issues. Can’t trust anybody! Call me cynical 🤨

It is the website of a company which describes itself as "The Experts in Cavity Wall Tie Replacement and Cavity Wall Insulation Removal"

I wouldn't expect them to promote the use of CWI.

In truth, it makes a difference whether CWI is being retro-installed into existing wall, or built into a new wall from scratch.  Many of the issues with CWI is where it has been installed in an existing wall with pre-existing defects, the CWI just adds to or exacerbates the issues.

If a wall is designed and built with CWI then there shouldn't be problems.

This is about retrofitted insulation. All new houses with a cavity wall have a cavity filled with either mineral wool insulation or hard-foam boards insulation. However, a proper cavity is usually 10cm+. Yours is too small. Possibly, because it's conservatory and doesn't have to satisfy building regulations.

Thanks for this,but more importantly why Section62? 🙂
