Hard Rock Concrete Cutters, Inc. was hired to assist in the repair of a downtown building by drilling multiple 1 inch holes that went 5 feet deep into the granite façade.
Drilling into granite 30’ above an active sidewalk and building entrance provided a few challenges. First, Hard Rock had to engineer and modify the coring rack and column in order to secure it to the scaffolding provided because anchors could not be used to secure the coring machine to the granite façade. Second, Hard Rock had to provide a method for collecting all slurry water to protect the pedestrian traffic which included many Lollapalooza Music Festival Fans. Each challenge was addressed and Hard Rock performed the work in a safe, clean, professional, and timely manner.
