squeaky floor and polyurethane foam

[SLAWEK]

Maybe silly question,

Is it a good idea to try stop squeaky floor by spraying in, trough a drilled holes a polyurethane foam? In theory, set foam should stabilize floor and reduce noise. The floor is a hollow one, chipboards on wood joints laying on the concrete floor ( it is not possible to drill in a concrete as it is too strong - already killed two professional sds high power drills ).I cannot put chipboard on a concrete as there is a loads of pipes and cables on it. Any ideas/suggestions?

Thanks everyone.

i have done it and it does work, but and a very big BUT. you have to be very carful about how much you pump in as it expands a damn site more than you think and it will lift the floor if you put too much in
