How to make vibration isolation of the washer and dryer?

Asked .Active .Viewed 235 times.

I plan to put a washer and dryer in the kitchen, one on top of the other. The floor in the room – dry screed. Underlayment – about 10 cm of sand and expanded clay, in place of the column – sheets Knauf thickness of 4 cm. The problem is that the back legs of the column will stand on a screed, through which the riser. This screed appears to be poured directly on the floor slab. There is a concern that the vibration from the machines will pass to the downstairs neighbors without loss. What can you vibro-insulate the column? The load is point, 4 legs of 25 kg.



Put pads of thick rubber under the feet of the washing machine.


There are special vibration pads under the feet of washing machines.

But not only a fragment of the cement screed, the entire dry prefabricated floor under the tiles will cause discomfort to the neighbors.

  • Why? There's 5 cm of native sand on the floor from under the old screed and another 5 cm of expanded clay on top. Some drum effect is observed, but it feels only in its side. 

My washing machine is on a rubber mat with a thickness of one and a half to two centimeters, glued together from pieces of rubber like a cork.

On the mat lies a tile of black chic porcelain 60x60 (bought on the market for cheap with a chipped rib). On top is a washing machine on standard rubber washing machine pads.

The neighbors did not complain, and washing at night does not cause me any discomfort. The only nuance. The machine must stand perfectly straight. At the slightest tilt of the plate from the vibration during the spin, the washer can crawl off the pedestal. Also considered instead of a rubber mat, special felt sports mats for archers, but settled on rubber.
