Joint in Concrete Slab
Joint in Concrete Slab
(OP)
I am working on an 80' wide by +/- 200' long metal building with a concrete slab. The owner is adding on to the 80' end of the building with an 80' x 150' addition. The existing wall will be removed so that the completed building will be 80' x +/-350' with an open floor plan and no surrounding pavement or walls. The building use will be light storage with some small forklift traffic. The new slab will butt against the existing slab so I am showing greased, smooth dowels at 32" o.c. drilled into the existing slab. I don't think a compressible filler is required between the existing slab and the new slab because there is nothing from preventing the slab from expanding outward, but another engineer in my office says to always put it in. What do you think? By the way, the slab will be poured in the next week at what will probably be the coldest temperatures that we see on an annual basis.

I have a project that I need to think about joint protection for light forklift traffic on CJs too, I'd like to hear other posters experiences and suggestions.

Leave at least 1/4" space past the end of the inserted dowel to allow for dowel expansion. Probably won't ever occur, but good to have a little space in there.
Consider using flat plate dowels. Those are good for thin slabs.

Going from 200' long to 350' long will definitely change things!!
