On the clothes washer's slowest spin cycle, vibration radiates out to 15' enough to loosen drywall screws and cause moldings to separate at seams.
To damp the vibration, we braced one of the two TJI's right under the washer with a 4x4. There is some improvement but not enough. We are looking for more ideas as to what can be done.
Should we try installing additional bracing under the TJI's in the location of the washer: more 4x4's, several permanent jacks, concrete block columns, etc.?
An additional possibility is to install vibration-absorbing pads. One product aimed at the retail market can be seen at http://www.kellettent.com/ (very slow loading website): the "LP-13 Shake Absorber® Vibration & Isolation Pad" described at http://www.kellettent.com/mountingpads.html .
The IQS Directory lists many suppliers of vibration absorbers, but they seem to be mostly industrial: http://www.iqsdirectory.com/pagetwoads.aspx?CatID 7.
We would be grateful for any thoughts, ideas, suggestions.
Thanks in advance.
