EcoSand® was installed on all of the major walkways around the $1.3 billion Levi Stadium prior to its opening in August of 2014. Where people are concerned about slip resistance especially where the walk area is likely to be wet, the solution until EcoSand® was launched, was sandblasting.
The problem is that sandblasting is a hazardous, very disruptive process and is banned in many countries. Sandblasting causes particles of silica sand and metal dust to hang in the air even after the sandblasting has ended. Workers using sandblasting equipment, or those who work in the vicinity not wearing respiratory protective gear, will inhale the dust particles. Many different chemical elements may be contained in the metal’s dust many with negative impact to the human body.
EcoSand® is a new process that eliminates sandblasting altogether and offers a more uniform look and more control over the design and surface performance. In addition to the safety factors, many architects and designers want a finish that shows off the sand tips in the concrete but with a uniform look. As regular concrete wears, these sand tips will be revealed anyway but the EcoSand® process will give a uniform finish across the entire hardscape versus random wear patterns depending upon the traffic.
Developed here in the San Francisco Bay Area by Bay Area Concretes, EcoSand® provides a safe alternative to sand blasting while giving architects and building owners more control over the decorative aspects of their walkways and floors. Using normal concrete on a heavily used walkway causes uneven wear and loss of a uniform look. With EcoSand® the surface looks just as good and without any wear patterns.
EcoSand® was installed by PolishedCrete for this project.
Bay Area Concretes has been innovating decorative concrete surfaces for almost 50 years including being the first installer of Bomanite stamped concrete and polished concrete flooring.
