If you go view the takeoff of Elon Musk's recent rocket (which did not have any water cooling jets employed) you can see huge chunks of concrete bouncing around everywhere. Some bounced right up and hit hydraulic lines inside the motor, some hit some solid state motors, and so in only a minute or so the rocket failed. Apparently the craters gouged into the reinforced concrete by the rocket motors were meters deep
