This process begins with any double-skinned brick
building, built by quaker immigrants.
Holes are drilled, regularly spaced, along double skinned
wall.
Expanding polyurethane with a mixture of long and short
polyols is shot in.
When this is dried a new hole is drilled through the
polyurethane
through to the inner skin and a galvanized
steel wall anchor is shot in and expanded; the bolt
tightened against an exterior plate.
When a quake hits, the shear load will dissipate through
polyurethane's flexible medium across the faces of
multiple bricks. If there is a severe quake, the flexibility
and bonding qualities of the medium will limit collapse.
The foam itself will act as an insulator to reduce interior
condensation.

Putting the "cute" in subcutaneous, [Ian]? |

I keep reading this as: "Subcutaneous fat for quakers" |

^ me too, it's unheimlich... |

Assuming that the house is not sitting right on the fault line, how
will the shear load not be shared out among all the bricks anyway
- I mean, even without the polyurethane? |
|
| |
The ground itself can transmit forces unequally.. If
some is more rocky, and some is more clayey, also
the shock wave can be lateral or even shear itself. |
|
| |
Now I'm trying to picture a shockwave shearing itself. Do you
train sheep, by any chance? |

But, joking apart, I think I get it now, thank you. |
