    Case Study: Concrete Stairs and Landing

 
        Before and After

   

 
The Assignment:
    Remove damaged stairs, create depth for new ones
    Adjust step rise height to be equal and legal.
    The stairs were of uneven height, one was too high.
    Replace.

 
Removal:  >  3 Tons
There were a lot of large stones in these stairs.
It made the removal more difficult and explained the damage.
The stone and concrete was briefly laid on tarp-covered plywood.

 
Partially Removed
Here is the debris from just 3 stairs.

 
Forms Up, Railing Set
You can see there will be a lot of concrete.
We removed about 15 inches of mixed stone and concrete.
The stairs had had layers of new concrete put on top.
But those repairs had never 'repaired' the original cracks.


 

LaFarge Delivers New Concrete
3 meters of new concrete are set.

Curing Concrete
Rebar and Steel Mesh installed.
Concrete poured, vibrated, now curing.
Each step is 7.5 inches high, 15 inches deep.

Forms Removed
We and the client are surface-wetting the concrete to add strength.
.

Equal, Legal, and Done.
No longer of unequal height, nor illegal height,
A very strong stairway, with railing posts buried deep.
The sides and vertical faces are parged for a smooth finish.
