Expansion joints in concrete

I'll try to answer them in order: 1) Installation isn't that hard. Since the reinforcing stops 2 inches from the face of the joint, the forms don't have to accomodate the lapped bars. They do, however, have to be split to allow the centerbulb of the waterstop to project through. 2) You model the wall as a cantilever.
