Ez-Spray® expandable rigid foam is often used to create large, lightweight elements used in landscaping.  It also increases productivity by reducing production time.  In the following example, the goal is to create custom, hollow, rocks for the purpose of concealing and housing outdoor speakers that blend in with exterior landscapes.

Using a Rebound® 25 mold previously used to create decorative rocks cast in concrete, the landscaper quickly employes the 
EZ-Spray® system to quickly produce durable, lightweight castings. Outdoor speakers are mounted inside. The rock speakers ad concealed audio ambiance to any environment.
