The build

Mull magnetic anomalies. A bit of light reading for a Saturday morning

If anyone is really interested there is a 15 page PDF you can download on the subject . The above was more than technical enough for me   .

Later in the build we’ll be looking at radon gas!

My eyes started to glaze just reading the title way beyond me.

Could it be part of "Magnetic North" and now that it has been moved all maps will have to redrawn?

Interesting info.

Well that’s a couple I never want to go for a pint with   . Luckily we don’t have to do any of that. We just have to fit a radon barrier under our floor slab. Basically plastic sheet .

I always thought it required a physical barrier, but there was no mention of it in the clip.

Just the same as an underfloor damp proof membrane which is general practice then, doing two jobs at once!

We were in a radon area in Devon and had a little monitor on the window sill ... given that MrPP used to work on maintenance and refit of nuclear subs, radon seemed like the least of our worries

Not the same, we have to have DP membrane as well . You guessed it another sheet of plastic. But a different colour, so that’s nice. And we need different tapes to hold the 2 together. Then there’s the other layer of stuff to stop the screed from eroding the insulation.

   

It’s all really quiet simple.........or not! 
And they missed a 0 off the compacted hardcore measurement !

Wednesday evening we went to see Ross ( the man that can work magic with a digger ) at the plot. Just as we were leaving I spotted a really pretty stone. Today I went back up the plot to see if I could find it again or if it had been covered over.
I found it 

  

The fact both half’s were next to each other and they fits together without any missing bits is very impressive ( well I think so   ) .

How lovely!! Anyone with an ology in Geology who can identify the rock and tell us what has happened here?

Surely you don't need a "ology" to identify and say what has happened, identity:- a stone, what happened:- Ross hit it with the diggereven

It definitely has metal content in it because a magnet is very attracted to it.

Did you spell that wrong, do you mean a chilli magnate, as you were attracted to it
