    Case Study: Chimney Repair, Articulated Boom

        Before and After

   

 
Chimney reconstruction

The Assignment:
    Rebuild the chimney with new bricks,
    The driveway is shared, and can not be filled with scaffolding.

The Underlying Problems:
    The chimney cap had holes, leaked, damaged the bricks.

 

 
Before
11 feet of chimney, using old bricks with no holes.

 
60 feet of articulated Boom.
We were not allowed to fill the driveway with scaffolding.
But the articulated boom allows us to reach all sides of the chimney.

 

The damage
Cracked chimney cap, holes, broken bricks, failed joints.

 

Removal
One can see the bricks without holes, but can't see they lifted without chiseling. They sat there with gravity only as the mortar had long failed.

Here you can see ceramic chimney flues - the top of each vent had one, only. None below.

No Flue Liners
Here one can see bricks are used to divide the chimney vents, with no ceramic flue liners.

The boom can carry 500 lbs, so many trips up and down are required to remove about 400 bricks.
heavy canvas drop sheets are placed on the roof around the chimney.

A secure base, below the flashing
We're using new bricks from the base up.
About five rows before the bottom we began to use a chisel to remove them.
All the bricks above had come off just by lifting them.
If someone had leaned a ladder against the chimney, it would have fallen over.

 

 

Chimney dust isn't good for you.
Wearing a high quality particulate mask is healthy, particularly during brick removal.

After building up about 15 rows we stop to tool the joints.

 

 

 

 

 

 

Done, covered with a tarp.
34 rows of new brick.
One can see the 5 point harness used to secure me to the basket.

The client's furnace team will place a cap on it.
