VDF FLOORINGS

A vacuum dewatering concrete flooring is a special type of flooring technique to achieve high strength, longer life, better finish and faster work. It is suitable for high abrasion and heavy traffic movement. The Vacuum Dewatered (VD) Flooring method is a system for laying high quality concrete floors with superior cost-effectiveness. The key to the use of this method is the dewatering of concrete by vacuum process. Surplus water from the concrete is removed immediately, after placing and vibration, reducing the water-cement ratio to an optimum level.

1)Adopting the VD flooring method facilitates use of concrete with better workability than what is normally possible.

2)A lowered water to cement ratio due to vacuum dewatering leads to improvement in each of the properties of concrete like wear resistance, compressive strength, less shrinkage and minimum water permeability.

3)Through the vacuum treatment, it is possible to reduce the water content in the concrete by 15-25% which greatly increase the compressive strength.

4)By lowering the water-cement ratio, the tendency of shrinkage and subsequent cracking is greatly reduced.

5)Since the water-cement ratio is lowered through vacuum dewatering, concrete of high initial slump can be used while pouring.

Advantages of vacuum dewatering concrete flooring method

• Reduction in W/C ratio leads to early setting and high strength.

• This system removes the excess water after pouring of the concrete & thus an ideal water cement ration can be achieved.

• Increase in compressive strength of concrete by 40-70%.

• The surface hardness of the slab increases by 130%.

• Water absorption is reduced enormously.

• Minimum dusts.

• Level floor, high flatness accuracy.

• Minimized crack formation, Shrinkage reduced by 50%.

• Improved wear resistance.

• Elimination or minimization of overtime.

• High and early strength, minimize damage to newly cast floors.

• Void-free & Denser concrete.
