Vacuum dewatering system or VDS is a set of four machines that are used to get a nice and hard concrete floor. The four equipment that help in dewatering process are double beam screed vibrator, vacuum pump, power floater cum trowel and groove cutter.
There are certain advantages of using de watering systems over normal concrete slabs:
- It reduces the water cement ratio compared to the normal concrete slabs.
- It increases the tensile strength of the floor. Here, also a rise in abrasion resistance when vacuum dewatering systems are used
- Faster initial strength gain in case where dewatering systems are used.
