Traditional methods of constructing stadium risers have used structural steel stud, timber framed or plywood formed concrete. Whereas PREFOAM™ DRY-FIT riser system involves the use of EPS Geofoam blocks as the primary material for a prefabricated system. 

EPS Geofoam is manufactured in different material types, with different physical properties and compressive strengths, based on the specific requirements of each project. The high compressive resistance and light weight of the EPS Geofoam, make it well-suited to both new construction and renovation projects. 

EPS Geofoam blocks are custom-manufactured in factory and shipped to site, then stacked on-site to create the desired profile. The modular system components are coded to match our detailed shop drawings, which clearly illustrate the exact size and location of each component to facilitate on-site coordination and timely installation.

One of the many other benefits of PREFOAM™ DRY-FIT system is the flexibility to shut down only half of the auditorium in an existing multiplex, while the other half stays operating during renovation.
