Process 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 & leveling. 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.

Benefits 1. Compressive strength of floor increases by upto 60% 2. Tensile strength increases by @ 70% 3. Cement consumption is reduced to the extent of 40%, no cement is required separately for finishing the surface. 4. Abrasion resistance of the floor increases by @ 60% resulting in les wear and rear of the floor surface 5. Shrinkage of concrete is reduced and floor wraps less.

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.
