Concrete Pumping Contractors San Diego - Can You Really Use a Trailer Pump?
Recently, we’ve seen numerous misconceptions surrounding concrete pumping but we’re here to set the record straight today. As strange as it sounds, it is possible to use trailer pumps in order to deliver large amounts of concrete. As long as you have the right tools and follow the right steps, anything is possible!
Before we continue, we should first explain exactly how concrete will behave inside a hose. For us, we start with priming agent and this allows the concrete to move freely through the hose. Then, we consider the rock size and multiply by four because, in all likelihood, three rocks will slide so there needs to be enough room (the extra 3/4 inch space is taken up by Portland cement, water, and sand).
With this in mind, the concrete should (theoretically) pass through nicely but you must understand there will still be blockages and issues at times. Although the aim is to leave 3/4 of an inch for the mixture, working with concrete is never an exact science. This being said, a three-inch hose will work as long as the pour is within 150 feet. If you’re looking at anything more than this, you should try four-inch hoses or maybe even larger to avoid confusion.
As you start to get larger and larger, new problems start to creep in like weight. As more concrete passes through, the tip hose operator will struggle to keep the hose in place and this is where hooks come in handy. With the weightier setups, you will also need extra people pulling the slack.
Fortunately, we are here to help with any project you may have as we specialize in big rock concrete pumping. Whether you’re limited by heavy mixes or long distances, we can help with the right skill set and experience to make it happen!
Why use a concrete line/trailer pump?
A line/trailer pump can keep your labor costs down by requiring less employees to be on the job site. The pump can go where concrete mixers cannot go. You can guide the hose as needed for each application or location for the placement and finishing of your concrete. We help you get the job done in a safe and cost-efficient manner.

Can concrete be pumped uphill?
Concrete can be pumped uphill, downhill, through small openings, across long distances, and around and under obstacles. Just let us know what you require and we will be able to help.
Why is some concrete not able to be pumped?
Concrete is made up of many different ingredients. Certain mixes such as exposed concrete have a significantly higher proportion of large rocks than a normal mix or duramix. The extra rock content can bind in our hoses, preventing us from pumping. Also, other types of non-pumpable concrete could include mix designs with too much sand.
Who pays for the concrete if it is not able to be pumped?
We try our best to pump concrete supplied by the concrete company that you hire. We do not supply concrete, so it is impossible to ensure that the concrete is 100% consistent from job to job. We will, however, make our best attempt to pump the concrete mix as long as it is safe to do so. However, we are not responsible for the cost of the concrete mix if it cannot be pumped. As long as it is in our schedule for that day, we can wait for a replacement load, but sometimes it is better if we can reschedule for another day.
What is the coldest temperature at which concrete can be pumped?
As we have been told, our concrete pump can pump in really cold weather, however we have set our limit at 32° Fahrenheit. If the weather is below 32° Fahrenheit, we will ask to reschedule.
