Vacuum-dewatered flooring, also known as VDF flooring, is a flooring system that is commonly used in industrial, commercial, and residential construction. It is a type of concrete flooring that is created using a specialized process that involves the use of a vacuum pump.
Process of VDF flooring
The VDF flooring process starts by laying a concrete mix on the sub-base of the floor. The concrete mix is then spread evenly over the surface using a screed board.
After this, a vacuum pump is used to suck out the excess water and air from the surface of the concrete, leaving behind a denser and more compacted layer.
This process helps to improve the strength, durability, and finish of the concrete.
Once the vacuum dewatering process is complete, the concrete is left to cure and harden. The surface of the concrete is then polished using a power trowel or a mechanical polisher to create a smooth and level surface.
Cost of VDF flooring
The cost of VDF flooring ranges from INR 70 to 120 per square foot in India.
Application of vacuum dewatering flooring
1. Industrial flooring: VDF flooring is commonly used in industrial settings, such as factories, warehouses, and manufacturing plants, due to its durability, strength, and resistance to wear and tear.
2. Commercial flooring: It is also used in commercial settings, such as retail stores, offices, and restaurants, due to its clean and polished look, low maintenance requirements, and ability to withstand high foot traffic.
3. Institutional flooring: It is suitable for institutional settings, such as schools, hospitals, and government buildings, due to its hygienic properties, resistance to stains and chemicals, and ease of maintenance.
4. Residential flooring: It is also used in residential settings, particularly in areas that require durable and low-maintenance flooring, such as garages, basements, and outdoor living spaces.
5. Sports flooring: It is commonly used in sports facilities, such as gymnasiums, arenas, and tennis courts, due to its ability to withstand heavy impact, abrasion, and foot traffic.
6. Outdoor flooring: It is ideal for outdoor applications, such as parking lots, sidewalks, and driveways, due to its resistance to moisture, chemicals, and stains.
7. Airport runways and taxiways: It is suitable for use on airport runways and taxiways, due to its high strength, durability, and resistance to wear and tear.
8. Bridge decks: It is also used on bridge decks, due to its ability to withstand heavy traffic loads and harsh environmental conditions.
9. Hospital and laboratory flooring: It is ideal for use in hospitals and laboratories, due to its ability to maintain a clean and hygienic environment and resist stains and chemicals.
Advantages of VDF flooring
1. High strength and durability: Vacuum dewatering flooring is known for its high strength and durability, making it suitable for areas with heavy foot traffic, impact, and abrasion.
2. Minimal shrinkage: It has minimal shrinkage, which reduces the risk of cracks and improves the overall durability of the flooring system.
3. Improved dimensional stability: It has improved dimensional stability, which means that it maintains its shape and size even under heavy loads and temperature changes.
4. Reduced drying time: Vacuum-dewatered flooring has a shorter drying time compared to traditional flooring systems, which can reduce the overall construction time.
5. Reduced curing time: It has a shorter curing time, which allows for faster installation and reduces the risk of delays due to weather conditions.
6. Better bonding: The vacuum dewatering process creates a better bond between the flooring and the substrate, which improves the overall strength and durability of the flooring system.
7. Low maintenance: It is easy to clean and maintain, reducing the cost and effort of upkeep.
8. Resistance to stains and chemicals: It is resistant to stains and chemicals, making it suitable for industrial and commercial settings that are exposed to harsh chemicals.
9. Hygienic properties: It is ideal for settings that require high levels of hygiene, such as hospitals, laboratories, and food processing facilities.
10. Customizable: It can be customized to suit the specific needs of the project, including color, texture, and finish.
11. Environmentally friendly: It can be made using recycled materials, reducing waste and promoting sustainability.
12. Fast installation: It can be installed quickly and efficiently, reducing construction time and costs.
13. Suitable for outdoor use: It is resistant to moisture, chemicals, and stains, making it ideal for outdoor applications.
Disadvantages OF VDF flooring
1. Slippery when wet: VDF flooring can be slippery when wet, increasing the risk of accidents and injuries.
2. Initial installation costs: The initial installation costs of It can be high compared to other types of flooring systems.
3. Noise level: It can be noisy underfoot due to its density and hardness.
4. Limited availability of skilled installers: It requires skilled installers, which can be a limiting factor in some regions.
5. Cold underfoot: It can be cold underfoot, making it uncomfortable in colder climates.
6. Cracking: It can be susceptible to cracking if the subfloor is not properly prepared.
7. Limited design options: It has limited design options compared to other types of flooring systems.
