Strip Mall Extension
Strip Mall Extension
(OP)
I'm designing an extension to an existing strip mall and I'm looking for tips for properly detailing the separation between the new and the existing building.
My question primarily relates to the location where the new slab on grade will abut the existing exterior wall of the mall. Should an expansion joint be provided at this location, or can the slab be cast against the existing wall?

Although the definition of "expansion" joint can me a lot of things to different people, what I picture as an expansion joint would be overkill here.

The elevation of the new slab on grade relative to the existing exterior wall has not yet been verified (thus it hasn't been detailed), though I presume it will be cast flush up against the concrete foundation wall.
My thought was to provide a separation between the slab and the wall with a joint filler, though I don't want to add cost if it's unnecessary. Mijowe- why would you provide a joint filler? and BAretired - why do you prefer not?
