VDF Flooring also known as Vacuum dewatering Flooring is a special type of Flooring technology for High Strength, longer life, better finish and work faster. This type of flooring is suitable for high wear and heavy traffic movement.
The Vacuum dewatering Flooring or VDF Flooring is a system for laying high quality concrete floors where the key is dewatering of Concrete by Vacuum Process in which excess water from the concrete immediately after placing and vibration reduce the water: cement ratio to the optimal level.
How to: In this system of VDF Flooring vacuümontwaterd Flooring is concrete or deposited and instead vibrated with a vibrating needle especially on the sides of the panel thickness more than 100 mm. floor Than vibration is done using a dual beam screed vibrator run across the surface, supported on channel formwork 4.0 metres apart from each other. The screed vibrator is performed twice in order to reach an optimal compaction and leveling. The vibrating surface is then evened out using a straight edge.
After this a system of lower mats & top mat is placed on the Green concrete and this is with a vacuum pump connected. This pulls excess water if any. The concrete is left stiffen. When the base concrete is stiffened to the point where walkable leaves a print of about 3-6 mm, Floor hardener used in a uniformly between 3-5 kg/m². Each flow water should now evaporated, but the concrete must be a wet shine. the concrete is then compacted and leveled using the Floater Power followed by the finish as per the requirement using power Trowel
Vacuum Dewatered Flooring (VDF)
We are leading service providers for Tremix Flooring or Vaccum dewatered flooring (VDF) & IPS Flooring. Various Floors in factories, warehouses and industries has extensive application of concrete which is a versatile flooring and has been in use for a long time. To mitigate the normal issues you face with concrete, a system was devised to improve the properties of concrete floors. This system is called Vacuum Dewatered Floors (VDF) or Tremix Flooring.
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 surface immediately hardens after this process & becomes workable. This is followed by running the mechanical power floater to level off the surface. The last process is working the power trowel to trowel off the final finished surface.
Advantages of Tremix flooring or Vacuum dewatered flooring over the conventional flooring:
Increased Compressive strength of floor
Increased Tensile strength
Reduced Cement consumption (No cement is required for finishing the surface)
Increased Abrasion resistance
Reduced water / cement ration
Increased Impact strength
Reduced number of joints
Less wear and tear of floor surface
Reduced Shrinkage of concrete
