Expansion Joint Depth
Expansion Joint Depth
(OP)
I am designing a 3-story, L-shaped, CMU building with hollowcore floors. The building also has a CIP basement. The grade varies along the exterior of the building so that the basement walls are partially exposed (roughly 3' to 4' maximum) in some areas. The building is essentially two 58'-0" wide x 225'-0" long buildings, with an expansion joint at the inside corner of the overall building. The precast spans in the short direction of each building section.

Typically on a building without a basement, we stop the expansion joint at the slab on grade. So my question is: Can the expansion joint stop just above the first (ground) floor? Do I need to provide the expansion joint through the 1st floor hollowcore but not the CIP foundation walls? Or does the expansion joint need to extend through the basement walls down to the top of footing?
Maybe I'm overthinking this, but any advice is helpful. Thanks.
Brian

Don't ask me what language that is.
The joint will magically appear and you will have a torn layer of waterproofing and a leaky wall.
