Andehh

UFH everywhere, and A2A in key rooms for short boosts of heat, and cooling during the summer. Unbeatable combo!! Slept like a (chilled) baby last few hot weeks!

Bitumen paint, a friend to many of us in these situations!!

Home insurance policy? Accidental damage etc?

Also be keen to see if ever an option ourselves!

Is that where it puddles by any chance or drains? How long since it's rained for you? We have it odd that after rain, as it dries... Some individual blocks look wet still, then lots around are dry... Almost dries like a checkerboars. Soon all driws the same.

Check check and check again! Some bellend changed the style of the windows, and builder failed to spot it... So we ended up with windows different to what we wanted to. Caused a lot of upset for many weeks... Our biggest build emotions.... But now forgotten and accepted. But windows can be one if the biggest single purchases, with so much choice and made to measure etc. We have the smart ally system and very happy with the windows, we just didnt want a central mullion l... Rather a single large pane of glass... But someone added the mullion be cause our windows were too big for single pane, but nobody told us until they arrived.

Anti crack mat for sure! We installed one, and still see a few cracks in the grout which need redoing, but touch wood no other issues. Similar sqm to you, laid in 75mm ish sand and cement.

Ain't water a bitch... Who needs it!!! You wouldn't have this issue with gin! 🍸

On the brightside , playing with concrete is always good fun! So you did that!!!

Ah mate

How often do you get flooded? During those circumstances I'd imagine you're gunna have bigger worries to work through!!!

How much insulation have you got below the UFH? And in the house in general? Tog slow the heat transfer , but don't stop it. Providing you have a good amount of insulation below you might not need to be too over zealous with the underlay, if there is a risk of compromising actual usability. (Ironic as we spent a couple grand on low tog carpet underlay, likely with a ROI beyond my own life span... But hey ho... )

Very satisfying!

Are you able to dish it/level it to push water away from the wall??

That gap between the block and historical stone work has got to be a major weak point to focus attention in?
