Concrete Pumping Contractor Del Mar
Indeed, It Can Be Done: Trailer Pump Can Be Used for Concrete Pumping in Del Mar
The thought of concrete pumping in Del Mar 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. But what about the stones blended with the concrete? 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.
There may be some instances when the pump will be blocked even if you use a primer. 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. If you need to pour from a longer distance, you will need to use a larger hose to ensure that the mix would flow properly.
Because the hose is heavier with the bigger volume of concrete flowing through it, the operator holding the tip of the hose may find it hard to keep it steady. But you may use hooks and more people holding the hose to stabilize it. However, the problem with having a bigger hose is that its weight will impact on the operation.
Regardless if you have a large or medium-scale project, we will be here to lend you a hand. We are staffed by experienced and skilled technicians who can help you resolve problems with your delivery of heavy concrete mixes over long distances. We can use our expertise to help you achieve the best results for your projects.

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. Well, that point is well taken as boom pumps are admittedly useful. Nevertheless, this kind of pump is how outriggers occupy a considerable size of space.
Just imagine how difficult it is for the boom pump to navigate a project site that is located in a congested area or where the power lines are in a messy situation. They are becoming more popular in the U.S., South America and even Europe. In spite of their being small, trailer pumps are also quite powerful, capable of delivering high-pressure pumps.
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. 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.
Trailer Pump Benefits
Many of our clients who used trailer pumps have not reverted to using boom pumps because of the extra space they were able to save. They also loved how the equipment is very user-friendly. The trailer type of pump produces lesser waste and offers lower pumping rates. This is simply because they are very easy to maneuver, give less waste, allow lower pumping rates and can be utilized in small spaces. 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.
Decision is Up To 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. However, you do have to factor in the location of the project, the deadline for delivery (including cleanup) and your budget, as well.
Gunite versus Shotcrete
Gunite is a type of construction material used in constructing pools. 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.
It is in this technique of application that gunite encounters problems. The quality of the mix depends totally on the accuracy of the onsite operator. There are no mechanical controls or reliable systems to ensure a dependable, long-lasting and correct mix.
Coring tests carried out on different parts of walls that are in the same pool could affirm irregularities. 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. A simple coring test will reveal inconsistencies in the application.
Shotcrete is the answer to your gunite problem.
Unlike the gunite mix, the shotcrete is computer-controlled. The mix is carefully designed and produced in a plant. The mix will adhere to the walls once you start to spray it.
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. With shotcrete you are guaranteed that the walls of your pool have a constant strength of 3,000 to 4,000 psi, thus preventing leaks and cracks from happening. With shotcrete, everything is done according to the highest standards.
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. 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.
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.
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. 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 is also a type D ditch, measuring 3 feet wide, and there is the trapezoid ditch, as well, that is recommended for commercial use. There are also 7-foot wide ditches that are 3-foot deep and constructed in trapezoid pattern, which is a requirement for certain commercial applications. The amount of water mixed with the concrete is crucial in building 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 soil, our technicians will put either a 6x6x10x10 wire mesh or 17-gage wire mesh depending on the predefined requirements. Our shotcrete team will then apply the concrete into the walls of the ditch. We strive hard to satisfy both the homeowner and the contractors by ensuring that the services we deliver are of the highest quality.
Part of our work is erosion control. By doing erosion control, we protect the slopes. 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.
The Gunite and Shotcrete Process
Gunite is the mortar that is sprayed on the surfaces at a high velocity. By adding small-sized coarse aggregates into the mixture, the procedure is able to generate thicker products, which making it more cost-effective in the long run. 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.
Guniting and shotcreting are nearly identical. Gunite was first used in the early 1900s. The technique used air pressure to apply mortar on walls, which were thinner than the ones we have now.
The pressure from the jet presses the material to the surface. Quick drying products like Rediset also accelerate the drying process because it solidifies in a matter of hours. The application doesn’t vary much between gunite and shotcrete. As already mentioned, it’s in the blending process which makes the latter superior in quality in terms of the final product.
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
In the wet-mix process, the concrete is blended with water just like in ordinary cement mixing. It is then passed through the conveyance pipeline to the spout, where it is pushed by compressed air at high pressure onto the surface.
However, more and more contractors have abandoned the wet-mix process because the dry-mix has been known to produce more stable and consistent results because of the low water content of the latter. High velocity or low velocity works well in the dry-mix process. The high-velocity gunite, which has a velocity of 90 to 120 meters per second, is produced with the aid of a small nozzle and high pressure. This produces good compaction results. Meanwhile, the low-velocity gunite is produced using a large diameter hose. The compunction, in this case, is not that high.
Benefits of Wet and Dry Process
Dry-mix application involves a lot of dust, which can be hazardous to the applicator. Also, the contractor can save a lot because the wet-mix doesn’t require as many hired hands as the dry-mix process.
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 proportion in the dry process is believed to be responsible for the lesser creep and stronger strength of the concrete made this way compared to the concrete delivered through the wet process. However, air-carrying agents can be used to enhance the solidness of concrete delivered through the wet process. Admixtures, for the most part, can be used more conveniently with the wet process, with the exception of the accelerators.
Another issue with the dry process is the possibility of rebound and the development of pockets of lean mix. The nozzleman has to understand this and must assign an area where he or she can place the shotcrete to be rejected in the course of adjusting the water supply.
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.
Also, it results in a lot of waste especially if the applicator has to adjust the nozzle or when the water content is less than satisfactory. While doing so, a large amount of the material will be dumped to the ground. 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.
