Rough concrete levelled for screeding

THE PREPARATION GROUP’s contracting division PPC, was contracted to level a 300sq m tamped concrete slab that had been laid for a new office building.

It had been badly finished off with visible raised areas and needed to be levelled in readiness for the application of a screed, followed by tiles.

For the first stage, the company used its 320 Planer to reduce the concrete, removing the high spots and levelling the area.

The 320 is a three-phase self-propelled planing machine with variable speed control and an adjustable cutting depth. It’s made from 8mm steel for the downforce and strength required to remove most stubborn materials including thermoplastic lines, roof chippings, screeds and self-levellers.

The second stage was to flatten and smooth the surface using a 250 Grinder. The result was a flat ‘profile’ ready for applying the screed and new floorcovering.
