Laser Screed

Summary

Laser Screed - A laser screed is a machine used to screed large areas of concrete floor rapidly.

Technical Information

The laser screed was first introduced to the UK in 1991 and it has since revolutionised the industrial concrete floor industry. It allows large pours to be screeded quickly and to a good level of flatness.

Lasers are used to ensure that the plough remains level and at the same elevation. At least one laser transmitter is set up so that it transmits lasers horizontally at a certain elevation across the warehouse. The lasers are detected by sensors above each end of the screed head which transmit data to it and automatically adjust it.

The screed head carries out three main functions which allow it carry out its functions in a single pass:

A plough spreads the concrete so that it is level.
An auger moves the excess concrete removed by the plough to the side.
A vibrator further levels the concrete and compacts it.

Once laser screeding is complete, the surface must be inspected thoroughly to ensure that there are no low points. Laser screeds can achieve a decent level of flatness if it is operated correctly by an experienced team.
