My gym is inside a multi storey building, on the bottom floor, and there have been complaints by other occupants in the building about the noise and vibration from our deadlifts. The bar also bounces a lot on this deadlift platform, so it definitely needs to be replaced and improved to fix both of these issues. The current set up is Strength shop granuflex mats (they are supposed to be good for vibration absorption, 20mm thickness I believe) on the gym floor (horse stall mat), one layer of 3/4 inch thick plywood on top of the granuflex mats, and a weird thin rubber layer on top of the plywood
If we were to place a new good deadlift platform (2 layers of 3/4 plywood plus a 3rd layer consisting of 3/4 inch plywood in centre and 3/4 inch horse stall mats on the sides) ON TOP of the granuflex mats, would that fix both problems (the vibration/noise being felt across the building, and the bar bounce during deadlifts)?
I am concerned the granuflex mats may lead to the platform having too much give/ bounce, but without the mats I fear the vibration issues won’t be fixed. I’m getting us a ‘good’ deadlift platform (as I described earlier) regardless, I just want to know whether the granuflex mats will help or not in such a situation?
The attached photo shows the current setup, the layer in between the plywood and gym floor is the granuflex mat for reference, it feels kinda squidgy tbh but I guess that’s how it works for vibration absorption.
We train on calibrated powerlifting competition plates. More controlled eccentrics isn’t really an option.
Has anyone got any experience with a similar setup? Any help is much appreciated, thank you.
