Bouncy floating bamboo floor
The question comes down to - when one walks on our new kitchen floor there is a feeling of bouncy and depression of the bamboo planks that doesn't feel quite right. There are also some irregularities in the concrete that may accentuate the movement in some areas. Should this be considered normal? The installer did a very nice job on the fit, appearance and trim work but the softness and movement was not something I expected. But we've never had a floating floor either.
How much movement do you normally feel in a floating type floor installed over foam underlayment?
Background: We had engineered Mohawk strand bamboo click and lock planks installed as a floating floor in our kitchen. The kitchen floor is concrete slab above grade. The bamboo was installed using their first quality 3 in 1 foam urethane type heavy underlayment pad. The underlayment was intended to serve as a humidity barrier, insulator, sound deadener and softener.
