Sv: [Strawbale] Thermo floor from snail-houses/mussels

[SVEN AERTS]

To prevent round snail shells from sliding and... There are regions where
you have underground mudd streams... Very strange thing.

Here in Brussels f.e. They exist too: its a mudd stream that keeps coming
and coming... Some construction companies here - when they were trying to
suck away the unsteady ground - kept on sucking that mud steam until 5
houses away there were some foundation problems raising... They had sucked
away all the ground... There's seems only 1 way to stop it and to inject
some hardening stuff in it.

In my system that would never happen.... My whole foundation is linked to
each other as a raster/network thanks to the cement milk.
Loads can be higher too.

Regarding the interest in my site... Let's co-organise some lectures.
