Preparation for the new concrete slab pour continues at 623–627 Cleveland Street with installation of a vapor barrier and expansion joint material. Crews fit the membrane around plumbing penetrations and extend it up the surrounding walls to help limit ground moisture from migrating through the finished floor, while the joint material is placed along the floor perimeter.
