Yes, It’s Possible: Trailer Pump Can Be Used for Concrete Pumping in El Cajon
The thought of concrete pumping in El Cajon or that trailer pumps can be used to convey immense loads of concrete were once viewed as outlandish; something that can’t really be done. We are here to explain how things work in complete detail. Unknown to many, cement can be pumped using trailer-mounted pumps.
Before we share how we were able to achieve this, allow us to envision a big hose with concrete streaming out towards one end. Well in our company, we begin by introducing a priming agent. This permits the concrete to move without restraint inside the hose. Then we make a careful estimation of the rock size and multiply it by four, making sure there is enough room, and leaving about ¾ inch of space for the cement, water, and sand. We also consider the size of the rocks and multiply it by four to ensure that the pump will not get blocked. There should be enough room for the water, portland cement, rocks and sand inside the pump.
Of course, testing and the real thing may sometimes be two different things. However, it is best to keep in mind that while we leave some space (3/4 inch) for the mix, getting the way around concrete could never be an exact science. In a further test, we discovered that such blockages could indeed happen if the hose stretches out past 150 feet. Otherwise, you may want to consider using the large hose. To make sure that the stream of concrete would flow easily, you can use a hose with a diameter of four inches or greater.
If there are more concrete mixture passing through the hose, you will need to use hooks because it will be harder for the hose operator to hold the hose. To remedy this, you may use hooks and assign more workers to hold the hose to keep it stable. In any case, the issue with having a bigger and heavier hose is that it may affect the operation.

Our Trailer Pumps Can Deal with Big Rock
The idea of using trailer pumps for pumping concrete to a slap may seem far-fetched to some people. If only they realize that pumps of this kind can handle big rocks just as well as boom pumps can. We believe that while boom pumps offer more power, the outriggers of the pump can take up a lot of space in the construction area.
Our trailer pumps can deliver grout mixed with pea gravel and even bigger stones. These situations call for an economical and efficient resolution, and we assure you the answer is using trailer pumps.
The Power of Trailer Pump
Trailer pumps are actually perfect when you’re working on fixing up either a commercial building or residential space. Why? It’s because these equipment pumps as much as 1,000 feet horizontally and 300 feet vertically. Trailer pumps may differ in some aspects, depending on the model, but you will find that most of them will have roughly the same pump kits, and that they will usually weigh no more than 10,000 pounds.
Trailer Pump Advantages
You wouldn’t how a lot of our customers have never returned to using boom pumps after experiencing just how good trailer pumps are. First of all, they are easier to operate. They also leave minimal waste.
If you use a trailer pump, expect to collect just one wheelbarrow of excess concrete. This saves you money and results in a better-executed project.
The Choice is Up to You
Obviously, there are pros and cons to each method. The technology used by most commercial pumps today is amazing so if there are differences, they are not significant enough to make a dent in your wallet. We also suggest selecting a pump that can help you minimize the space needed for the equipment and the cleanup time and expenses.
Gunite versus Shotcrete
If you are planning to have a pool in your home, making a research about it will likely lead you to a product known as Gunite. The concrete mixture is pushed through the tube using pressurized air. Water needs to be added to the tip of the nozzle in order to control the flow better. The wet mixture passes through the nozzle and sticks to the wall where it is sprayed.
Gunite is made by dry mixing sand and cement right on the site itself, and then pushed inside a 3-inch hose with the aid of a large compressor. A nozzleman determines how much water to add in the nozzle tip that comes with a special water-ring. The by-product leaves the nozzle by way of pressure.
This particular step is quite tricky. How good the mixture turns out depends on the skill of the workers. There is no exact formula that will guarantee perfect results. Coring tests made in different sections of the same pool can confirm these inconsistencies. The end result is a pool with weak walls that could collapse due to cracks and leaks. This results in a pool with walls that are liable to break down due to leaks and cracks.
Shotcrete is the answer to the gunite problem.
All anomalies in gunite are precluded with the use of a computer-controlled mix from a concrete batch plant where each truckload of shotcrete is manufactured under rigorous supervision. The wet material, concrete, is pumped through a two-inch hose to a nozzle with an air-ring, giving it the property to stick to vertical walls.
Because of the accuracy of the process, shotcrete is now the preferred choice of material by the California Department of Transportation in the construction of bridges and retrofitting. The mixture can also be used in making pools since it can maintain up to 4,000 psi which helps prevent water leaks.
Most of our projects involve residential pools. We have constructed and repaired countless of pools in San Diego, all with astounding results. Throughout the years we, together with other contractors, have seen the benefits of shotcrete over gunite.
We have been working with private property owners who subcontract their pool projects to us. At first, they asked for information about the service we provide and inquired about shotcrete. We offer recommendations when requested and answer any inquiries concerning shotcrete that will help people in accomplishing the project that they exactly have in mind.
Pools have seen extensive improvements through the years. Some of the newly built ones have more complex features such as vanishing edges, waterfalls, and fancy rocks. Our company has been the pace-setter in this development. Our help has been sought by many pool builders and homeowners who know fully well our capacity to deliver the best results even in the most challenging conditions.
Drainage ditches are made to minimize water buildup in a property. In most cases, drainage ditches have a six-inch concrete lining. Most of the drain ditches for residential properties measure two feet wide and one foot deep. We can customize the structure depending on the function and purpose. The volume of water blended with the concrete is very important in constructing these ditches.
The San Diego County Book of Standards features many ditch designs. We can build whatever kind of ditch you need, utilizing our 191Kabota excavator. After digging the ground, our personnel will place either a 6x6x10x10 wire mesh or 17-gauge wire mesh depending on the specified requirements. Whether you are a contractor yourself or a homeowner, you can count on us to deliver the needed serve to your utmost satisfaction.
In building ditches, we guarantee that there will be no erosion by ensuring that the slopes are well protected. We do this by applying shotcrete on the walls in differing thickness, even without reinforced steel bars. We also engage in erosion control in basements and underneath houses and other structures to keep water from undermining their foundations. Some slopes are in nearly vertical walls where we apply shotcrete with a rough nozzle finish that conforms to the shape of the slope. Slopes with vertical embankments are shotcreted with a rough finish, taking the shape of the slope. There is another slope type which you may often see in commercial applications, but may also be used in residential homes. Slopes of this kind are usually fine-graded, with wire mesh.
Gunite or Shotcrete?
Gunite is the end-product when mortar passes through a hose and propelled at high pressure to the surface. When sand or small coarse aggregates are used to add thickness to the mix and to make the product more cost-effective by reducing the cement content, the end-product is called shotcrete. We also use the newly created “Redi-set cement” in the shotcreting process. Ordinarily, newly applied cement with no droppings can support itself without inclining or peeling off.
It can be expected that materials with no slump will be able to stand on its own with no danger of sagging or peeling off.
On the other hand, shotcrete is a new development based on the same principle as guniting but producing walls of greater thickness with the addition of small coarse aggregates. Two different processes are used—the “wet-mix” and the “dry-mix.” The dry-mix process is generally more effective and the one most commonly used. The process of shotcreting, on the other hand, developed only in later years to yield thicker and small coarse aggregates.
The dry-mix process is done this way:
(a) Cement and sand are thoroughly blended.
(b) The cement/sand mixture is put in a special air-pressurized mechanical feeder called “gun.”
(c) The blend is measured and placed in the conveyance hose by a feed wheel or distributor.
(d) This material is pushed by compressed air through the conveyance hose to a special nozzle. The nozzle is placed inside with a perforated manifold through which water is passed and blended with the sand/cement jet.
(e) The wet mortar is ejected at high pressure from the spout onto the surface to be gunited.
The Wet-Mix Process
Concrete and sand are mixed with water before being fed into the delivery system and sprayed onto the surface through compressed air. The application concept is very much like your garden hose. You train the nozzle to where you want the mixture to go.
The wet-mix procedure is no longer used as much today as it has been found to yield less successful results compared to the dry-mix procedure. High-speed gunite is made by using a small nozzle to discharge the concrete mix at a speed of around 90 to 120 meters per second. This results in extremely high concrete compaction. Meanwhile, the low-velocity gunite is produced using a large diameter hose. The compunction, in this case, is not that high.
Advantages of Wet and Dry process
In the wet process, you can be able to accurately control the ratio of water to cement, but the ratio must not be too low, an issue that is better addressed by the dry process.
Pumping light-weight aggregate content is best done using the dry process. It must be pointed out that the dry process depends a lot on the water content of the sand. Excessively wet sand causes obstruction inside the conveyance pipeline, a problem that does not happen in the wet process.
There is a lower water/cement ratio used in the dry mix process, which is why the ending result produces more durable concrete. However, it is worth noting that you can use air-entraining agents to strengthen the concrete is you prefer using the wet mix technique instead.
Pouches of lean mixture and rebound can happen with the dry process. It is essential for the nozzle operator to have a place where he can dump poor quality shotcrete obtained when he is still modifying the water content or when he is experiencing difficulty with the equipment.
Because there’s no prior blending that occurs in the dry process, you really have to monitor the water content, which can cause an obstruction to the hose or nozzle. Rebound is also quite high in this method compared to the wet mix.
The personal nuisance and hazards caused by dust in the air during the dry process are experienced less often by technicians during the wet process. However, unlike the dry process, the wet process does not consistently produce compact concrete. Due to the high limits that concrete pumps produce, a higher rate of concrete laying can likely be accomplished using the wet process rather than the dry process.
