I was pumping grout up to the 4th floor of a building today, and they had me setup next to a crane.

apparently with this crew, Riding the crane is normal

Its probably OK footing, but i dont like having spaces between my cribbing

That seems kinda unsafe in many ways.  I hate cranes, always getting in my way, and of course they get the prime spots.  They couldnt have hired a line pump to pump grout?  And it looks way thick.  They grouting by hand?

small spaces on thick timber like that = no problem at all. can help make the area bigger = spread the weight more.

I run the same pump its an old pumpcrete pump from Toronto.  Its old reliable.

goose, they were flling cracks in the concrete panels so they requested a pump. probably could have been done with a trailer, but for some reason they prefer using a pump.

and boomer, do you work at pumpcrete too?? 

and they wanted it at that slump because they said it filled in better. what they are doing is dropping a pile onto the ground then they use squeegys and spread the grout in between the pre cast panels so they are flush
