Cold Joint


Carefully Crafted Cold Joint

Someone asked what the line in the wall of the butcher shop was. It’s a cold joint. It’s where we ran out of money.

This happened a number of times since we didn’t have any bank financing or government grants to pay for things. Instead we would save up our pennies and then pour concrete when we had enough money. Meanwhile we worked on the forms and got ready, got ready, got ready.

You’ll notice that the cold joint in the photo is sloped so that water won’t run into the building – much like shingles on a roof. I did this quite intentionally and carefully since I knew we wouldn’t have enough money to fill the forms all the way. Necessity is the mother of invention.

In addition to making slopes on the cold joints I also keyed all the cold joints and stuck chunks of granite in them. These bind the sections of pour together much like building a mortared stone wall. I also purposefully made them uneven, out of plane, so they bind together even better.

Since these are all compression joints it works. The next section sits down on the previous, interlocked and shingling to keep water out. The top isn’t going anywhere.

Put this technique on the list of innovations caused by tight budgets.

Later when we had more CSA Pre-Buys, Kickstarter and some loans from friends we had fewer cold joints. Put that on the list of less stress and preferred construction. If I could I would setup all the forms and injection mold the building all in one quick shot. Dream construction…

Call yourself Kazoo.
