High Street — Heavy Exposure Concrete Floor Finish

High Street is the most recognisable and preferred diamond polished concrete floor finish, suitable for newly-laid or existing concrete, and is ideal for refurbishment projects in residential or commercial settings. The floor is ground flat revealing a mixture of heavy stone and fine aggregates, that are then resin diamond polished. This full exposure best emphasises the underlying aggregates in the concrete.

The process requires the removal of 3-5mm of the concrete laitance to reveal the underlying aggregates. The floor is created using well established Megafloor processes with internationally recognised and quality assured, equipment, tooling and chemicals.

Megafloor finish and sheen options can be selected for the desired performance and gloss level for the application.
