Screeding Rails

Concrete screed rails are tools used for the correct leveling of concrete floor bases. By setting two screed rails in parallel, at equal heights and level, it's possible to level a wet concrete pour by dragging over wide rakes, vibrating screed levelers or other tools.

Screed rails can be either a permanent fixture in a slab, offering such advantages as crack control and reduced labour, or they can be removed after leveling.

Screed rails can also be used as shuttering for concrete slabs to prevent concrete egress into other areas, and even as a framework for other construction systems. Many systems, including Combiform and K Form, also offer pre-drilled holes for dowel sleeves and rods, allowing continuation of steel reinforcement across slabs and concrete expansion and contraction control.
