Finnish footing foam…

One of the ideas behind ShopHouse is “healthy”.  Things like indoor air quality are important to us.  We’re spending a lot of time on HVAC, but even the materials in the overall construction are important decisions and opportunities to make sure our indoor environment is the best if can be, as well as making sure that we at least try to choose environmentally decent materials.

Additionally, we’re incorporating a split footing design, where 2 halves of the footing are thermally isolated from on another, and also insulated from the ground (more on THAT project shortly).  So – we needed a source for 4″ xps foam to get the R values we needed AND it needed to have sufficient compressive strength to hold up the house (minor detail).  The search started with the usual suspects – Dow, and other companies that seem to be more chemical that insulation…

And… then we find out that all the foam insulation that appears to be available in the US contains HBCD (Hexabromocyclododecane – there will be a spelling quiz later – so pay attention) – a bio accumulating chemical that is banned in Europe and in the process of being phased out globally.  It’s a flame retardant and blowing agent.  Read the link for a more detailed discussion on why this is bad stuff.

Why would we want THAT all in the ground around our house and under the slab?  It doesn’t need to be flame retardant, and we’re anti – nasty chemical. So intrepid husband starts the search for happy foam to make our footings.

The US companies’ answer for removing HBCD is just to find a better chemical and make everything flame retardant.  Sigh.

Enter – FINNFOAM!

In northern Europe, apparently what we’re doing isn’t all that odd, and Finnfoam complies with the stricter chemical regulations of the EU.

So we’re now experts in importing Finnish Foam by the container.  Interestingly enough the cost was equal to the “blue foam” even including ocean freight.  We paid for the foam to be delivered and then unloaded it all into our trailer and basement.

Another round of my personal slave labor.  That was an entire 40 foot – high cube container…..

Now – on to the form making!

Site ready…

Summer is long over.  And the site is finally READY!!!

I am pretty sure I would have never anticipated this project taking this long.  My latest joke is that the pyramids were built faster.  But hey – they had slave labor and the only slave labor around here is MINE.  We’re tackling a lot of things ourselves, and perhaps that’s the right thing, but perhaps not.  I do know that we will have a one of a kind project when complete, but that completion is likely being driven to a later date because of some of our decisions.  In the overall scheme of things, that’s not a big deal  –  I mean after all, this is our “forever house”  but I am still ready to “get going”.

The site looks outstanding – it seems so long ago that the northwest corner was down about 10 feet.  Standing in the corner that will be our bedroom / master bath area you do feel like you are in the trees – but still on ground level.

Never thought I would be this excited about dirt...

We had an issue with the cistern floating because we had not completed our backfill, so that was a repair issue.  But – we then decided to add some drainage into the cistern excavation.  Good thing, because that hole DOES.  NOT.  DRAIN.  We’ve installed a 4″ corrugated drain pipe, completed the 2″ first flush drain, installed most of a 12″ drain for the cistern bypass during really heavy rains, and still have a 6″ cistern overflow and a 15″  stormwater drain to install.

Believe me - it's a lot more painful than it looks.

Believe me – it’s a lot more painful than it looks.

We’ve basically done this all by hand.  On a good note, I don’t need to go to the gym. (today…)
