Concrete Pumping Contractor La Mesa
Indeed, It Can Be Done: Trailer Pump Can Be Used for Concrete Pumping in La Mesa
The thought of concrete pumping in La Mesa 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. We made such a sensible notion a reality by using proper equipment and developing new systems.
Prior to getting into the nitty-gritty of things, it’s only fitting that we first get to know how concrete works while in a hose. We are able to do this by adding priming materials on the concrete to make it run through the hose smoothly. Next up, we check just how big the rocks are and then multiply that size by four. Why? 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.
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 found out that such blockages could indeed happen if the hose extends beyond 150 feet. Otherwise, you may want to consider using the large hose. Otherwise, four-inch hoses or hoses larger than that should be used if you are working with a distance more than what was stated.
In any case, the issue with having a bigger and heavier hose is that it may affect the operation. 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.
Opportunely, we are here to be of assistance to you in your projects. We have a workforce of licensed, experienced and highly skilled technicians who can resolve your problems on the delivery of heavy concrete materials over long distances. Our specialty is dealing with large rock concrete pumping.

Our Trailer Pumps Can Deal with Big Rock
We’ve heard that nervous laugh numerous times whenever we put forth the idea of pumping concrete to a slab using trailer pumps. We’ve also heard how people are sure about using only boom pumps in handling big rocks. 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. Hence, we advise using trailer pumps instead. Trailer mounted concreate pumps are very economical and they work like a charm. In spite of their being small, trailer pumps are also quite powerful, capable of delivering high-pressure pumps. No, trailer pumps are not just for pea gravel and grout. The fact of the matter is trailer pumps are being utilized across South America and in several countries in Europe.
Trailer Pump Power
If you’re remodeling a commercial establishment or a house, trailer pumps are perfect since they can pump up to 300 feet vertically and more than 1,000 feet on a level plane. By and large, they can even achieve volumes of 70 cubic yards per hour. They can even work with as much as 70 cubic yards an hour in nearly all cases. While a model may slightly differ from one to the other, it’s likely that they come with the same boom pumps to pump kits and may weigh as much as 10,000 pounds.
Trailer Pump Benefits
You wouldn’t how a lot of our customers have never returned to using boom pumps after experiencing just how good trailer pumps are. They also leave little waste, their pumping rates are minimal, and they can be located even in cramped spaces. The problem with using a boom pump is that a large part of concrete stays inside the container, leading to major losses.
Alternative Boom Pumps
Boom pumps have been known to create a lot of waste. For instance, a huge piece of concrete is jack-knifed into the hopper every time a boom pump is utilized. That huge piece will already be counted as a waste considering that it could not be taken out. The estimated cost of waste each time this occurs is around $160. That’s how inefficient the boom pump is. The viable alternative is the trailer pump where, overall, the amount of waste may possibly fit one wheelbarrow. By increasing efficiency and reducing the amount of waste, you will only increase your profits in the end.
Which Option is Best For You?
There are various types of pumps used in the industry today. We recommend choosing a type or model that fits your budget and satisfies the needs of your project. The choice may ultimately hinge on whether you want to save money. If that is the case, then the use of trailer pump is your best choice.
Gunite versus Shotcrete
Gunite and shotcrete are sometimes used interchangeably. But the two methods are distinct from each other. 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.
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. You will need to do the Coring tests to check for any signs of inconsistencies. Otherwise, the walls of the pool will crack or worse, cause major water leaks.
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 perfectly regulated shotcrete mixture is used by the California Department of Transportation in constructing highways, bridges plus seismic retrofits. The result after the application is almost always around 3,000-4,000 psi, which is way above the 2,000 psi limit.
Most of our work is done in building residential swimming pools. We have done numerous pool projects in the San Diego area, earning for ourselves the expressed satisfaction of our clients. We have been using shotcrete in our projects, and we are not surprised to know that some contractors are now preferring this material to gunite, too.
For homeowners who may be on a budget and prefer to do most of the work on their pools, we also offer advisory work. We provided answers that satisfied them, encouraging them to choose us as partners in their projects.
Pool construction has seen major improvements through the years. Some of the newly built facilities have high-tech features such as vanishing edges, waterfalls, and artificial 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
Drainage ditches are narrow channels dug on the ground and lined with three to six inches of shotcrete. A typical drainage ditch, called type B ditch, is 2-foot wide and 1-foot deep. There is also a type D ditch, measuring 3 feet wide, and there is the trapezoid ditch, as well, that is recommended for commercial use. Refer to the San Diego County Book of Standards for more of the ditch specifications. Needless to say, whatever ditch you have, we have the equipment and the technology to excavate the water.
For commercial and agricultural applications, such as for irrigation for instance, drainage ditches may range from three-foot wide to a width of as much as seven feet, along with a three-foot depth. After digging the soil, our technicians will put either a 6x6x10x10 wire mesh or 17-gage wire mesh depending on the predefined requirements. Our specialists will then pour shotcrete to form the walls of the ditch. Our shotcrete team will then apply the concrete into the walls of the ditch. 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.
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 do this by applying shotcrete on the walls in variable thickness, with or without reinforced steel or as circumstances require. We likewise use shotcrete to upgrade the strength of bridges, highways and other government infrastructure projects. We can also do erosion control in private ventures. We can construct fine-graded inclines with wire mesh in different structures and with a smooth or broom finish.
Gunite or Shotcrete?
Gunite is a concrete mixture sprayed at a very high velocity. The mixture is made by combining portions of sand and cement. Recently, a new addition to the mixture was introduced. This is the coarse aggregate which serves two goals: first is to cut down the cement content, which will save some money; and second is to produce both greater dimension and consistency to the final output.
Gunite has been around since the 1900 so this is not a new technology. Nevertheless, in some applications, it’s still as relevant as it was in the early part of the 20th Century.
On the other hand, shotcrete is an improvement of gunite. Its use results in the building of more durable walls with greater thickness. 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 and Application
(a) The standard ratio of cement and sand is thoroughly mixed.
(b) The resulting mixture is then added to the “gun,” which is the industry term for the automated feeder
(c) The concrete blend is pushed toward the delivery hose and nozzle
(d) The nozzle itself has a chamber for both accelerator and air. Meanwhile, water is introduced into the mixture through the water ring within the nozzle.
(e) When the mortar passes through the chamber, it becomes wet enough to be spewed out of the nozzle with the help of the high-velocity air.
Whether dry-mix or wet-mix, the rule of thumb is this—the bigger the nozzle, the lower the velocity of the delivery is going to be. High-velocity jet, for instance, can reach speeds of up to 120 meters per second. As can be expected, the higher the velocity, the more the material will be packed in once it adheres to the target surface. On the other end of the spectrum, lower velocity delivery may not be as stable in comparison.
The Wet-Mix Process and Application
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. The lower speed gunite, on the other hand, is passed through using a big hose for bigger concrete load yield. The concrete compunction is less under this process.
Advantages and Disadvantages of Wet and Dry 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.
Pumping light aggregates is best done using the dry process. It must be noted that the dry mix process is largely dependent on the amount of water mixed with the sand. Sand that is too wet causes blocks inside the pipeline, an issue that does not occur in the wet process.
The lower water/cement ratio in the dry process has been found to be the reason for the lesser creep and tougher strength of the resulting concrete product in comparison to the concrete delivered through the wet process.
The dry process often produces pockets of rebound and lean mixture. The nozzleman needs to get rid of the low-quality shortcrete. This means that you may need to have an additional designated area for the waste materials.
These inconveniences and the hazards posed by dust happen less often during the wet process.
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. The wet mix procedure will allow you to lay the concrete faster during a windy weather as compared to the dry method.
