Doing big rock concrete pumping with a trailer pump? yes we can do it

as long as you use the right tools for the job, anyone can make it happen. Most people believe that because you are using a trailer pump, it’s nearly impossible to deliver 57 stone (3/4 inch rock) to a big slab.

First is Important to understand how concrete behaves inside of the hoses. We start by using a priming agent to allow concrete to slide easier thru the inside of the hoses, then we factor in the size of the rock and multiply it by 4. We do this because there is a big percentage of chance that 3 rocks are going to slide side to side, and there has to be enough room for these 3 rocks. Water, sand and portland cement take the extra 3/4 inch gap, but understanding that even though concrete will make it thru, there will be times where you are going to plug up these hoses as well, because by leaving an exact 3/4 gap, you are too precise and concrete is never perfectly homogeneous. So once you know the size of the rock is 3/4, you can safely use a 3″ hose if the pour is not too far away, say 150 feet MAX. If you are pumping anything over this length of hoses, you definitively want to use a larger diameter hose to avoid head aches, like a 4″ hose for example.

The problem now becomes a weight problem, the tip hose operator is going to have a harder time holding this size hose, and more than likely he would have to use a hook (shown in this video). Also there is a need for additional guys pulling the slack of the hose to be able to keep up with the pump.
