Inquiry (采购产品): void grouting below slab I'm putting together an estimate for the building owners. one month ago a interior rain leader for a 4 story building ruptured during a heavy storm below the bottom floor slab. The water pressure blew sand and water above the slab and flooded the building. Approximately 25 lf of slab seperated at the expansion joint between two particular steel columns. One side settled approx. 1.5" down from the other. **** Hidden Message ***** Moe Villano 06067 Company: Connecticut Carpentry Corporation E-mail: mvillano@ctcarpentry.com **** Hidden Message ***** mvillano@ctcarpentry.com
