The Somero S-485 Laser Screed® is incredibly easy to operate and a very powerful 4-wheel drive machine. It is very multi-functional as well as capable of fine grading most subbase materials, raking concrete level, or for screeding of concrete to very high floor levelness standards, including world record setting and Golden Trowel® Award winning performance. Its lightweight design allows for utilization either on grade or on most decks (level or cambered), ice rinks, or chaired mesh or rebar. Add the optional 3D Profiler System and greatly expand your opportunities.
