Oct 26: Masonry Walls

Our mason, Brad Bonny, starts his work day on-site by laying-out the dry stack concrete blocks in the corner behind the location where the wood stove will be, between the Living Room and Dining Room, right.
The block wall is actually a double block wall with space between for insulation, as shown in the photo below.


A close-up view of a corner block, below, shows that it is not an ordinary concrete block, but rather a ground concrete block. The colors in the aggregate are exposed by grinding the surface smooth on all exposed sides, plus the top and bottom are ground smooth for the block to be dry stacked without mortar.  Finally, the edges have been bevelled to create a block with integrity.





An interlocking feature of the block adds strength to the vertical joints in the dry stacked wall, shown in the photo above.

Brad sets-up his masonry saw to cut the first course, which is only 2-1/2" high.


Lotte and Deschutes have found a place in the morning sunshine against the east wall of the Morning Room beneath the window sill.
