And this is probably the primary disadvantage of the precast process. You have to transport the Countertop to the job site without breaking or cracking it.
Another disadvantage is the need to make templates. "It takes a lot more time and traveling [to do this step]," reports Tom Ralston, president and chief executive officer of Tom Ralston Concrete in Santa Cruz, Calif "We use door skins to get the exact angles. [And] if different people do the measuring and the mold, some headaches can occur."
Nonetheless, precasting allows you to work on several projects simultaniously Buddy Rhodes, president of Buddy Rhodes Studio Inc. in San Francisco, observes, "Precast Counters [are] more suited for making more thanone project at once. Also, if [the countertop] goes 'south' you can make it again and have a happy client."
