How A Laser Screed Works
The Somero Laser Screed is a self-propelled four wheel drive, four wheel steer unit with a telescoping boom. The combination of different head width and boom reach ensure that our machines will fit your application.
The machine's automatic laser control system ensures an accurate level finish through the use of electro-hydraulic controls. Laser receivers mounted at each end of the screed head receive a signal from a transmitter multiple times per second providing totally automatic control to finished floor level.
A single laser transmitter controls up to 1000 ft (or greater depending upon model) enabling the screeds to work to a tolerance of 3mm or better.
Concrete is discharged in strips to match the size of the machine approximately 1" higher than final grade. The Laser Screed moves into position and the telescopic boom extended over the discharged concrete.
The screeding/compacting head is then lowered to the grade established by the laser-level transmitter. Retraction of the boom causes the screed head to be drawn across the fresh concrete which is leveled and compacted in a single pass. Once a pass is completed, the machine is repositioned to the right with some overlap on the previously screeded concrete. The operation is repeated, ensuring optimum finished level tolerances are attained across the whole floor area.
The screed head itself consists of 3 parts: the plow, the auger, and the vibrator. The plow disperses the concrete evenly, the auger removes the excess material to finished grade, and the vibrator smoothes the surface.

3-D Profiling
Laser Screed America Rentals utilizes the Somero 3-D Profiler System which allows concrete to be placed over contoured sites automatically using a Somero Laser Screed. The highly accurate Laser Screeding of concrete, until now restricted to single and dual plane applications, is now available to meet the demands of real 3-dimensional paving.
What Does Faster, Flatter, Better Mean?
Faster placement — A Somero® Laser Screed can screed up to 50,000 square feet per day, easily moves around obstacles on the jobsite and needs only perimeter forming when placing slabs-on-grade. An SXP equipped with an LS-12.5 head has a 12-1/2 foot wide head and 20 foot telescopic boom which makes it possible to screed 240 square feet in just 60 seconds! That means more floor is placed daily and production schedules are satisfied or actually shortened. Fast track production, high quality, and cost effectiveness are all direct benefits of utilizing the Somero Laser Screed.
Flatter floors — You get laser-precise flatness and levelness every time, using a Laser Screed. Floors are routinely flatter and more level than floors produced with any other conventional method.
Better quality — The Somero Laser Screed creates the highest quality concrete surfaces.
