Re: [papercreters] Re: Construction Question

Hi Bob,  Good questions. As far as joints I am think of a tongue and grove that would be actually part of the drying frame mold so that the panels dry in a shape that make them interlocking. Once in place one could come along with a bucket of PC perhaps a bit more portland rich and with a trowel complete the unions thus making the surface look like a uniform panel.  As far as the the top plate for joist and rafters goes this would all be a wood frame.  Runners along the floor and the plate would act to secure the PC panels in place.  This is how I did it with EPS panels in my last home and it worked very well.  The house even withstood a 6.2 earthquake 3 weeks ago and we were located only 2 miles away from the epicenter!!!!  I hope this makes sense.  I have done it with one medium and it just struck me that it could be done with PC panels. I will be working out the kinks in the next month with my shed.  Hope this all makes sense.  Any observations would be great!  -Tomas

Tomas, I like your idea of light weight panel walls of PC. How would
you attach these each other and to the floor or slab and what about a
top plate for ceiling joist and rafters?

Hi Bob,
Just built a house in Costa Rica using pier and beam foundation and
although I had planned my light weight panel walled construction
before hand it struck me while building that PC wall panels would
have been perfect for the job (light weight, great r-factor, etc.). I
have not heard of PC panel construction mentioned yet in this group,
but for my next construction I am planning on using it.  Basically I
am going to pre-make large PC panels approximately 8' by 4' by 5
inches wide and then place them into the frame of the home. I am
currently experimenting with panels of this size with a chicken wire
core and others with treated bamboo to give rigidity to the panels.
My roof will have a large over hang thus limiting the amount of
direct contact with rain.  But your idea of piers I think would
greatly increase the viability of PC construction (while taking
advantage of it's light weight, etc.) thus eliminating some of the
hassles of foundation seepage, wicking, etc. prone to PC construction.
I am making a storage shed with this type of construction first here
in the Philly suburbs and hope to get it done by late Feb. depending
on weather.

My Question is; "Has anyone built a pier and beam foundation, at
least 24" out of the ground, top it with a treated 2x8 mud seal,
applied rim joist and floor joist of treated 2x8's then applied wire
mesh to the bottom of the floor joist after installing rough-in
plumbing, and then filling between the joist on top of the wire mesh
with papercrete, then installing a wood floor and complete the
structure with papercrete walls, topped with a 2x8 treated top plate
and finish off with truss rafters?"

Bob
