If you only needed 900 PSI, you could use cheap CO2..

So, you need some kind of reservoir that has big opening for filling grout. It must be big enough to hold enough grout otherwise you will get voids. Also it must be strong enough otherwise you will be a local terrorist

I don't think pushing grout with just gas pressure is a good idea. You need pump.
