Concrete Casting

Casting concrete into rubber molds lets you make perfect copies of any original every time! Mold rubber can often be applied right at the job site. They can be brushed on, poured on, or sprayed onto a model. Urethane rubber molds cure overnight and last in production; saving you time, labor, and material costs. Both urethane and silicone mold rubbers can be used to make architectural elements, concrete stone veneer, large scale formliners, concrete countertops, GFRC panels, concrete stamps and more.  The high abrasion resistance and toughness of urethane rubbers such as Vytaflex® mold rubbers allow for a very long production life.
