Anyone cleaned a cork pool deck?

Have a customers brother that needs his deck cleaned. I was told that it has cork pieces in the cement. I have not gone to see the deck and have never seeing this type of deck. Anyone ever done one of these and could shed a bit of help on this? Thanks in advance.

Turns out this was a rubber deck and after talking with the installer of it I did this job today with a bit of help with EBC. Owner of the house has asked for a bid on the roof,house, and drive way. That made my day a great one!
Before ,during after,. First time with EBC at a customers home, very impressed, another great chemical,cleaner, ease of work solution.
