Concrete Pumping Contractor National City
Concrete Pumping in National City Via Trail Pump? It’s Possible
Concrete pumping in National City or the notion that trailer pumps can be used to deliver huge amounts of concrete were once considered impossible or something that can never be done. In a rebuff to doubters, we have demonstrated that indeed it can be done. 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. But what about the stones blended with the concrete? The remaining ¾ inch of the equation is in consideration of the water, cement and portland cement that would go with it.
Given this, there’s a likelihood that the concrete would be able to go through smoothly. You cannot avoid blockage issues, but you still need to leave at least 3/4 of an inch for a smoother flow of the concrete mixture. 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. Otherwise, four-inch hoses or hoses larger than that should be used if you are working with a distance more than what was stated.
The bigger load is going to wear the tip hose operator out eventually, the reason for the hooks. If there’s more and more concrete passing through, keeping the hose in place will be a struggle. Since the hose is larger with a bigger mass of concrete moving through it, the technician holding the nozzle may find it difficult to keep a firm grip on it.
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. 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.

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. Although it is true that boom pumps can do that, these pumps have one noteworthy shortcoming: Their outriggers consume a lot 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. Hence, we advise using trailer pumps instead. Trailer mounted concreate pumps are very economical and they work like a charm. Contrary to the belief of many, trailer pumps are actually spectacular equipment that can effectively pump even in the lowest slumps. Trailer pumps are definitely not just for small rocks. And many countries are now making this discovery as well!
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 Advantages
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. 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.
The Choice 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. 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 or Shotcrete: Which is Better?
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 liquid material is then sprayed onto the swimming pool, for instance, at high velocity. The liquid concrete will then stick to the walls or floors, as the case may be.
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.
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. The end result is a pool with weak walls that could collapse due to cracks and leaks.
Using shotcrete is your best option to avoid dealing with inconsistency issues.
Gunite problems are no more, thanks to computers and technology that make it possible to come out with an accurate mixture. Shotcrete (concrete) is made using regulated standards. As such, inconsistencies are eliminated, enabling the concrete to pump through the house and adhere to the vertical walls without a problem.
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. Having said this, you can be assured that your pools have a steady potency of 3000 to 4000 psi, greatly diminishing the possibility of leaks for many, many years. With shotcrete, everything is done in the exact way it should be done!
Pools
Most of our projects involve residential pools. We have constructed and repaired countless of pools in San Diego, all with astounding results. 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.
In addition to building pools, we have also been active in assisting homeowners who want to subcontract the work so they can make their own pool for years. 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. We have mastered our craft and we can very well build the pool that you have in mind. Thousands of homeowners trust us for our excellence and our commitment to delivering premium quality results.
Drainage Ditches
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. 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.
Many of the ditch designs are specified in the San Diego County Book of Standards. We can dig whatever type of ditch is required, using our 191Kabota excavator. 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.
Anti-Erosion Measures
Controlling erosion is another service we provide. Actually, this service is mostly geared to maintain the integrity of the slopes. This we do by placing shotcrete, and reinforcing it with steel if necessary. 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. 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. We can construct fine-graded inclines with wire mesh in different structures 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. This material is produced using higher air pressure to make the cement harder and tougher. We sometimes use quickening agents to help in the overhead placement of shotcrete.
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.
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. The dry-mix type of shotcrete is considered more durable and the one preferred by most users.
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.
Today, more contractors have been shifting to the dry mix technique because it offers greater success compared to the wet-mix method. The dry-mix techniques employ high-speed or low-speed system. High-speed gunite is created by using a small spout to release high air pressure to deliver concrete mix at a velocity of around 90 to 120 meters per second. 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.
Benefits of Dry and Wet Process
Although it is conceivable to get more exact control of the water/cement proportion with the wet process, the fact that this proportion can be kept very low with the dry process negates the complaint of the absence of precise control.
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.
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.
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.
Another point to consider is that the wet process can work better especially in windy sites. On the upside, when work is halted, the operator doesn’t have to rush to clean the equipment unlike in the wet-mix where concrete will solidify on the nozzle and hose. Hard-to-access areas would also benefit from the dry-mix delivery system, while the applicator exhibits more control of the nozzle and hose because they are lighter. It’s also more efficient when you introduce admixes because they can be applied on command.
