What radon protection did you use?

9 years ago

Is the grpund floor a solid slab or suspended block and beam with just the membrane for radon protection? Many thanks for any insight into this

Hi Johnny,

Thank you for your query and apologies that it has taken a little while to respond.

To answer your questions:

Here in Cornwall, only 'half-measures' are required by building control i.e. radon-proof membrane. There's no requirement for sump, or de-pressurisation pipes and extract fans.

It's a solid ground-bearing slab - concrete on DPM, on sand, on hardcore with insulation boards over slab and then polished concrete layer. As the building is Grade II* listed, then full building regulations take second place to preserving and not compromising the historical value and fabric of the building, so some modern requirements can be relaxed or not done.

We would suggest that you ask your project advisor be clear about what is best for the building and then discuss with building control.

I hope that this is helpful and good luck with your project!

Hi weezer16. I've had the same problem several times. If I were you I would keep to a fairly simple shape like a drum e.g http://www.pagazzi.com/shop-for-lighting/ceiling-lights/davis-extra-large-pendant-silver.html I can't tell from your photos whether a warmer colour would go better but the shape won't detract from the wall paper on the chimney Brest and ties in with the fairly simple mantle but a larger size will stop it blending into the background. Then you can add a bit more interest with your cabinet lighting etc.

I'd say we all want to live in that lovely house we passed whilst on the way to go brambling with a jam jar in our hand and high hopes of a good day. Maybe it was the gates, or the gravel driveway that appealed, and it even had stone pillers and Georgian windows . And I'd wait and stare, and wait and stare curious about who lived there and hoping they'd drive out allowing me a quick glimpse of another world. Them. Then I'd feel ashamed stood there in my jumble-sale-new clothes, bothered that perhaps someone might come out and ask me what was I doing. I learnt it was a very rich person home, a shipbuilder who owned a shipping fleet and I wanted to copy him, if he could do it- then so could I. So that man and that lovely house blighted my life for the best, and it still does. I love this house and stop outside it whenever I pass by. I'm heart broken, and I'm a big strong man and big strong men are not allowed to cry. That adopted house is my comfort blanket, my home, and I go to sleep and it becomes mine.This is my lounge, this my garden, this gate is mine, and please come in when you go brambling. Don't walk on by, share it with me, you can adopt upstairs or the fireplaces, or ceiling coving and florals, I won't mind.

Lots of the UK has a radon risk so it is not practical to avoid properties that fall into these possible areas. As I understand it the risk is low as we all routinely breath this gas daily. I understand that the normal course of action is to buy the house and an indemnity insurance policy. Once moved in an inexpensive test can tell you if you have slightly higher levels than normal and then if necessary the insurance policy pays for any remedial work to vent the gas safely which means a pipe that looks like your soil pipe is installed from your foundations to the roof. You do the test after you move in as the results are more accurate over a 90 day period. I have never actually had this issue so you may want to collaborate this information with your solicitor.
