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 watercement ratio to an optimum level.
Adopting the VD flooring method facilitates use of concrete with better workability than what is normally possible. 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. Through the vacuum treatment, it is possible to reduce the water content in the concrete by 15-25% which greatly increases the compressive strength. By lowering the water-cement ratio, the tendency of shrinkage and subsequent cracking is greatly reduced. Since the water-cement ratio is lowered through vacuum dewatering, concrete of high initial slump can be used while pouring.
Advantages The vacuum treated concrete floor/pavement, exhibits inherent advantages viz. Monolithic, Shrinkage free pavements. Single panel without joints upto 100 sq. meters (depending on design specifications) Very high splitting strength. Very high quality pavements in terms of strength of the pavement is increased giving flexibility to adopt wither leaner mix or design a slab of lesser thickness giving the required strength. Controlled and uniform surface finish. Very high output exceeding 100 to 200 sq. meters. in a day (depending on the configuration of Vacuum Dewatering System and other site conditions like concrete mixing and pouring speed)
