    Case Study: Brick Sill Creates Wall Damage

 
        Before and After

   

 
    The Assignment:
        Repair a brick wall with cracked bricks, poor joints.
        Use a sill stone with drip edge instead of brick on top.

    The Underlying Problem:
        The masonry and bricks on the top row had cracks letting water in.
        Sills made of bricks are inherently weak, and should be stone.

 
The Problem: A Sill made of Brick
We knew there would be water behind the wall.
The vertical masonry joints between the bricks had failed.

 
The Damage: Rotted Wood, Mold.
There was water and mold on the insulation, and the damage spread up.

 
Worse than Expected!
Water entry and a humidity imbalance led to extensive damage.
Minor maintenance would have prevented this.

The original chimney and stucco team was called in to repair the chimney.

 

Ready to Rebuild
With a concrete base to build upon, new brick is used.

Brick ties are used every 3 rows, to connect the brick wall with the plywood inner wall. Brick ties are screwed into the wall and are placed in the mortar joint to connect the two.

In new earthquake strategies, the brick ties are connected to handles on the wall that allow up and down movement.

Weeping Holes Balance the Humidity
Holes between some of the bottom bricks will allow the air between the bricks and inner wall to equalize.
Done, with Sill.
The Sill's joints are caulked, as required by Building Code.
The sill joints are no longer done with cement.

The bricks were cut to fit the dryer vent.

Silicone is used to caulk around the sill.

Built for Canada's Weather
Now the original chimney and stucco team takes over to finish the job.

The work site was kept clean throughout.

Parging was also done.
