Concrete Pumping Contractor Poway

Concrete Pumping in Poway With A Trailer Pump, Why Not?

The thought of concrete pumping in Poway 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. Trailer pumps can handle concrete pumping jobs of all sizes. Despite it being rather small the machine is actually very powerful, and coupled with the right knowledge, it can do a lot of wonders!

Before we share how we were able to achieve this, allow us to envision a big hose with concrete streaming out towards one end. We can do this by adding priming agent on the concrete to make it flow through the hose. But what about the stones blended with the concrete? 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. 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. Nevertheless, a three-inch hose should work out just fine if the pour is up to 150 feet only. 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. To make sure that the stream of concrete would flow easily, you can use a hose with a diameter of four inches or greater.

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. 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.

We know these things because we are specialists in rock concrete pumping. Our specialty is dealing with large rock concrete pumping.

Besides concrete pumping, we can also set up house lintels, tie beams, sauna tubes, preform columns, sink holes, power jacking, and slabs. We provide only the first-class array of line pumps. With this, we are able to draw out rock, grout or pea rock in all sizes up to an inch in diameter.

Our Track Record

As soon as you call us and agree to use our services, we will meet with your structural staff to make a detailed plan for your project. We could be your partner in building commercial or residential foundations, in waterproofing or even in decorating your home. Over the years, we’ve worked on hundreds of various projects with varying requirements. With our track record, building a retaining wall is the least we can do.

House Lintel Pumping

Our service price includes the setting up of 50 boards on the walls to provide 50 clean outs in house lintel concrete pumping. But if your requirements go beyond this, then we will adjust. Just let us know so we can discuss the matter thoroughly. Before we start the project, one of our technicians will check the down cells to make sure they are in good condition. We will then prepare the mixer and check the truss straps. We work with great efficiency. Because of the “j bolts” we place in the garage header and because we make it a point to clean the walls and ground after our operation, you won’t even know that we have already finished the job when you come to inspect. We will then check all the inspection holes before removing the boards and nails.

Our Trailer Pumps Can Deal with Big Rock

When we try suggesting using trailer pumps to transfer concrete mixture to a slab, we often get a dubious look from our customers. Once we explain the procedure, they tell us that it is not possible because we should use concrete boom pumps instead. 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.

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. Our trailer pumps can handle not just grout and pea gravel but also bigger stones. They are widely used not just in the U.S. but also in South America and even Europe.

Trailer Pump Power

In case you’re renovating your business establishment or residence, trailer pumps are the most suitable equipment for delivering concrete since they can pump up to 300 feet vertically and more than 1,000 feet horizontally. They can even accomplish volumes of 70 cubic yards per hour. Trailer pump units have slight differences, but they all weigh up to 10,000 pounds and are generally furnished with similar pump kits to boom pumps.

Benefits of the Trailer Pump

As we have experienced, a great number of trailer pump customers no longer ask about boom pumps, even if the project site is wide enough to accommodate the gigantic equipment. This does not come as a surprise, considering that they do get the same results without worrying about space, waste products, and costs. They can be operated even in a cramped location. Best of all, the cost of using them is comparatively low.

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.

Which Should You Choose?

The decision on whether to use boom pump or trailer pump is of course up to you. All modern concrete pumps are marvelous equipment. In the last 20 years, technological improvements have made these pumps more powerful and yield better results. Thus, it all boils down to your project budget – whether you want to save hundreds of dollars during machine cleanup time.

Gunite vs Shotcrete

Gunite is a material that has been used for a considerable length of time in building 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. 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. 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 your gunite problem.

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 application is mostly the same, however. You still have to use a hose and compressor to spray the liquid material to the pool walls and floors.

The latter is the preferred method of new construction today. In fact, the California Department of Transportation has ordered that only shotcrete will be used in roads, bridges and retrofits. By using shotcrete in pool construction, leaks will be highly unlikely. Choose shotcrete because it is accurate and exact; no more guessing games.
Pools

The vast majority of our work is in building private pools. We have finished many pool projects in the San Diego area, for which we have gained our customers’ seal of approval. Throughout the years we, together with other contractors, have seen the benefits of shotcrete over gunite.

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 can guide the process of application to make sure it’s done correctly and passes the standard for strength.

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 guidance has been sought by many pool developers and property owners who have known of our capability to produce the best results even in the most difficult 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. 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. The San Diego County regulates most of the specification of drainage ditches. Our company can help your dig and create the right type and size of ditch that you need for your property. Whether you are a contractor yourself or a homeowner, you can count on us to deliver the needed serve to your utmost satisfaction. 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

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. Nevertheless, we can introduce mechanisms and measures that will ensure the integrity of the project. Shotcrete sprayed in slopes will be vulnerable—even with reinforced steel—to water movement if we don’t introduce anti-erosion controls. There are also slopes with very steep inclines that they are almost vertical. But we’ve used the methods that we designed particularly for these situations.

Gunite or Shotcrete?

Overall, gunite has taken a backseat to shotcrete in terms of efficiency and stability. But gunite can also serve its purpose in select projects because the procedure is cheaper, at least initially. Typically new materials with zero droop can bolster itself without leaning or peeling off. The high-pressure application of the shotcrete makes the material tougher. 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. 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 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

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.

The wet-mix process has generally been cast aside in favor of the dry-mix process, because the latter produces much better results. The dry-mix technique can either use low velocity or high velocity, depending on the compaction needed for the project. Smaller nozzles are used to achieve higher velocity. The nozzle velocity can reach up to 432 kilometers per hour. Meanwhile, the low-velocity gunite is produced using a large diameter hose. The compunction, in this case, is not that high.

Advantages and Disadvantages of Dry and Wet Process

Although more accurate control of the water/cement mixture can be done through the wet process, the fact that the mixture is kept exceedingly low in the dry process counteracts the objection on the lack of precise control.

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.

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.

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.

Even though the wet mix technique will help you avoid more waste materials and dust hazard, you will not be able to get a dense mortar, unlike if you use the dry method.
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.
