Missing Bricks

We are in the process of demolishing the West gable wall.  This was due to the appearance of significant cracks on the outside and loosened stones on the inside.  I have noticed that where the brick lining is missing is where the damages have appeared.

You will notice, in the picture above, when you click on it and enlarge it, that there is a crack that runs from top, where the cross is, down through the circular and semi-circular openings.

You will see from this picture above that the West gable wall is not brick lined like the North gable wall pictured below.

The deterioroation of the stones in the picture above is due to the portland cement wash on the exterior stones.  Since it is not porous it has caused the deterioration of stones all over the exterior of the Cathedral.  There are no structural cracks in this wall.

The inside of the West gable wall is lined with bricks except for one place.  The stones in this place have become loose and buckled inward.
