What is vdf flooring?

VDF Flooring

also known as Vacuum Dewatered Flooring is a special type of Flooring Technique to achieve High Strength, Longer Life, Better Finish and Faster Work. This type of floor is suitable for high abrasion & heavy traffic movement.

In this system, concrete is poured in place & vibrated with a Poker vibrator. Then a screed vibrator is run over the surface, supported on channel shuttering spaced 4.0 meters apart. The screed vibrator is run twice to achieve optimum compaction & levelling. After this a system of lower mats & top mat is laid on the green concrete & this is attached to a vacuum pump. This draws out excess water. The concrete is left to stiffen. When the base concrete has stiffened to the point when light foot traffic leaves an imprint of about 3-6 mm,a suitable Floor Hardener should be applied at an even application rate of between 3-5 Kg/Sqmt.

 Any bleed water should now have evaporated, but the concrete should have a wet sheen. The concrete is then furt

her compacted and levelled using Power Floater followed by finishing as per the requirement using Power Trowel.
