We are a firm having expertise in Vacuum Dewatered Concrete Flooring [TREMIX]. Mr. V.K.SAH, the key personal, has been in this trade for more than 12 years. One of the pioneers of Vacuum Dewatered Flooring [VDF] Kolkata W.B.Odisha and Jharkhand Bihar.
Unfortunately, today’s VDF scene has been hijacked by one-time labour operators, knowing nothing about the actual significance of the process. These fly-by-night operators have access to the equipment but not the technology & perform works at low rates, which are always attractive to clients. Many a times, vacuuming, the very heart of the process is not done.
We in corporates the technical aspects of this fine process & gives you the ‘real thing’. Being qualified civil engineers, we understand & know the theory behind the process. Significance of dewatering is clearly understood. The advantages of this process as detailed on the page “Benefits” has been verified with test reports ourselves.

Floors in factories & industry have always been a source of problem in the production areas. Abrasion of floor, breakage due to lower compressive strength etc are some of the prime reasons for failure of concrete floors.
Concrete being the most versatile of flooring material, has been in use for a long time. To overcome the deficiencies of concrete, a system was devised to improve the properties of such concrete floors. This system was “Vacuum Dewatered Floors”. This system permits us to add as much water for making concrete workable & easily pourable. Normally addition of water beyond a point reduces the strength of concrete. All the same, to mix the concrete well water used is generally more than the optimum water cement ratio. This system removes the excess water after pouring of the concrete & thus an ideal water cement ration can be achieved.
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. 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.
The process is ideal for concrete roads too & is widely in use.
Some Of The Benefits This System Has Over Conventional Floors Are:
- Compressive strength of floor increases by upto 60% resulting in higher structural strength & therefore durability.
- Tensile strength increases by @ 70%
- Cement consumption is reduced to the extent of 40%, as no cement is required separately for finishing the surface.
- Abrasion resistance of the floor increases by @ 60% resulting in less wear & tear of the floor surface.
- Permeability is reduced as a result of which liquids falling on the floor have less detrimental effect on the concrete.
- Impact strength is increased.
- Shrinkage of concrete is reduced & the floor warps less.
- Numbers of joints are reduced as this method allows long strip floor as against conventional checkered method.
- Floors can be put to use much earlier because of lesser curing time.
- Water/cement ratio is reduced by @ 18%.
