Indeed, It Can Be Done: Trailer Pump Can Be Used for Concrete Pumping in Campo
The thought of concrete pumping in Campo 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. However, in a rebuff to doubters, we have demonstrated that indeed it can be done.
Before we reveal how we made this possible, let us imagine a large hose with concrete flowing out on one end. We are able to do this by adding priming materials on the concrete to make it run through the hose smoothly. Our team uses a priming agent to improve the viscosity of the mixture. In a test, we discovered that a mass comprising of three stones can slide easily through a hose with a three-inch diameter together with the portland cement, water and sand.
Ideally, the concrete should be able to pass through the hose without any problem, but there are times when its passage is not that easy due to stumbling blocks along the way. It has always been our goal to leave about ¾ inch space to accommodate the mixture, but apparently, it is not always the same case every time. In a further test, we discovered that such blockages could indeed happen if the hose stretches out past 150 feet. Having said this, it’s safe to say pouring within 150 feet would work just fine with a three-inch hose.
As the load becomes heavier, more manpower will be required. In this case, having hooks will be of great help. Getting an extra pair of hands to pull the slack is also beneficial when it comes to weighty setups. 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.
Whether you are dealing with heavy mixes or lengthy distances, there’s no need to fret as we have the knowledge and right skill set to make your projects become realities. Our specialty is dealing with large rock concrete pumping.

Effectiveness of Trailer Pumps in Cramped Spaces
Some people think we’re just boasting when we discuss our use of trailer pumps for delivering concrete to a project site. They can’t seem to understand that this is possible. They say only concrete boom pumps can deal with big rock. They say only concrete boom pumps can handle big rock. Yes, they are right, boom pumps are great indeed.
I’m sure you know very well how frustrating it can be to work on construction sites at the heart of a very busy city or maybe with power lines getting in the way. They are becoming more popular in the U.S., South America and even Europe.
Powering the 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 pump units may not look exactly same, but they all weigh up to 10,000 pounds and are generally outfitted with similar pump kits as those used in boom pumps.
Benefits of the Trailer Pump
A considerable number of our clients have shifted to using our trailer pumps instead of boom pumps even if they have the space in their project sites for those big machines. They have realized the many benefits offered by trailer pumps. Unfortunately, the leftover concrete can’t be used during cleaning time, which costs around $160 for each cleaning session. To us, this is a lot of wasted money. If you include the original cost of the boom pump, the cost will just continue to grow.
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.
Decision is Up To You
Whatever type of pump you want, it is yours to decide. Modern pumps offer numerous benefits, so it is not like you will be at a losing end when you choose one over the other. Things have changed a lot since the early years of concrete pumps. So it will now just boil down to how much you can afford and whether or not your space is suitable for your choice of concrete pump.
Gunite versus Shotcrete
Gunite is a material long used for building swimming pools. It’s a mix of sand and cement, blended dry onsite and pumped through a three-inch hose using jets of air from heavy-duty compressors. Water is put through a ring in the nozzle of the hose, with the volume controlled by a technician. It’s a blend of cement and sand, mixed dry onsite and driven through a 3-inch hose utilizing air from powerful compressors. Water is placed inside the spout tip through a special water-ring, with the volume controlled by the operator. The material leaves the spout as a packed wet compound that sticks to walls.
However, the application relies mostly on the skill of the nozzleman to do the job well. While the worker can control the speed and volume of material that is sprayed out of the hose, there’s just no uniform standard of application that ensures the quality of work every time. This means gunite is very vulnerable to cracks and brittle construction.
Deviation, no matter how small, in the mixing of dry materials and water causes a reduction in the pressure rating, which is set at 2,000 psi. If there are problems with the consistency of the mixture, chances are the pressure ratings will be less than the recommended 2,000 psi.
Shotcrete is the solution to this gunite issue.
All irregularities of gunite are ruled out through the use of a computer-controlled blend from a concrete batch plant where concrete is fabricated using strict guidelines. The wet material, concrete, is pumped through a two-inch hose to a spout with an air-ring, enabling it to stick to vertical walls.
The regulated controls on the concrete product have prompted the California Division of Transportation to use only shotcrete in the construction of bridges, expressways and seismic retrofits. The mixture can also be used in making pools since it can maintain up to 4,000 psi which helps prevent water leaks.
We are very proficient in creating whatever shape or size of residential swimming pools. Whatever design you have in mind, we can create it for you. Our team has created several pools all over San Diego, California, and all of our past clients were very happy with the end product. Through the years, our company has been using shortcrete to make our clients’ pools, so we know for a fact that this is the best mixture to use.
Homeowners who wish to subcontract their pool project may also approach us for assistance. We are always willing to provide expert advice if you ask, and if you want some clarifications about shotcrete, feel free to tell us. We provided answers that satisfied them, encouraging them to choose us as partners in their projects.
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. From a simple design of a hole in the ground, we now introduce additions like waterfalls, fountains, simulated oceans and invisible edges long before other companies followed suit.
Drainage ditches are narrow passages dug on the ground with walls lined with three to six inches of shotcrete. A common drainage ditch, called type B ditch, is two-foot wide and one-foot deep. There are other sizes and shapes of ditches. A type D ditch is 3-foot wide and 1-foot deep. The volume of water blended with the concrete is very important in constructing these ditches.
For larger commercial properties, drainage ditches that measure seven feet wide and three feet deep are used. Commercial drain ditches mostly come in a trapezoid shape. The San Diego County Book of Standards outlines the different specifications for the various types of drainage ditches. Our 191Kabota excavator is very useful in digging a ditch according to the specified requirements. We do our work in full view of the contractors and homeowners, allowing them to see with their own eyes how we can easily come up with excellent results in the service we provide. We strive hard to satisfy both the homeowner and the contractors by ensuring that the services we deliver are of the highest quality.
Roadway and foundational erosion control is also another major aspect of our specialty. We do factor in the environmental conditions surrounding the construction site and study documented geographical conditions to limit the risks. We do this by applying shotcrete on the walls in variable thickness, with or without reinforced steel or as circumstances require. We also do erosion control in basements and underneath houses and buildings to prevent water from weakening their foundations. Some slopes comprise of nearly vertical embankments where we place shotcrete with a rough nozzle finish that follows the shapes of the incline. We also use shotcrete in commercial projects to strengthen bridges and roadways. We can also do this in residential projects. This way we are able to build fine-graded slopes with wire mesh in various forms and with a smooth or broom finish.
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. Water is only added once the dry mix is inserted inside the hose. In recent times, coarse and fine aggregates are also combined with the dry mix to improve its thickness. The added components also help lessen the amount of cement used.
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.
Thanks to the air pressure coming from the compressors, the sprayed mixture becomes compact once it adheres to a vertical surface. Sometimes, the process requires using set accelerators. In case of emergency repairs, you can use the Redi-set cement. It is a newly developed material that easily sets. There are very subtle differences between shortcreting and guniting. For example, shortcrete is newly introduced, while gunite was introduced to the industry around the early 1900s. The two mostly differ in the thickness plus the use of small coarse aggregates. Gunite does not use aggregates unlike shortcrete.
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 and Application
In the wet-mix process, the concrete is mixed with water just like in normal cement mixing. It is then placed in the transport pipeline to the nozzle, where it is propelled by compressed air at high pressure into the surface.
By and large, the wet-mix process has been set aside since the dry-mix process yields better results. The dry-mix methods utilize fast or low-speed processes. 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. Higher velocity results to better compaction. If you want to achieve a lower velocity, you need to use a large nozzle.
Advantages and Disadvantages of Dry and Wet Process
A few examples of the pros and cons of using the dry and wet mix procedure are discussed in detail below. Although we can control the water and cement ratio in the wet mix method, it is more recommended to use the dry mix method instead.
The dry process is an ideal choice when you are using light-weight aggregate. Then again, if you are using wet sand, the procedure will not be as effective because there are sensitivities it just cannot handle.
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.
Nonetheless, air-conveying agents can be used to improve the strength of concrete that passed through the wet process. In general, admixtures can be used more advantageously in the wet process.
Pockets of lean mixture and rebound can occur in the dry process. It is important for the nozzle operator to have a facility where he can put low quality shotcrete that is produced when he is still adjusting the water content or when he is encountering trouble with the equipment.
However, unlike the dry process, the wet process does not regularly yield compact concrete. Work can proceed even during windy condition with the wet process, unlike in the dry process. Work can continue outdoors even during windy weather with the wet process, unlike in the dry process. The wet process also results in higher rate of concrete laying.
