Learn More About Our Shotcrete Services

We specialize in the application of Shotcrete. This form of concrete is applied at high pressure through a nozzle, if you’re not familiar with the method. Shotcrete passes through the line wet, much like pre-mixed cement, with water added at the nozzle.

We don’t just create pools; we also provide full-scale Shotcrete facilities to all of our clients. You’ve arrived at the right place if you want to create anything with this innovative technology. Please contact us to learn more about our capabilities and to begin working on your next project!

Concrete Design & Build

Nova SCP has a long history in shotcrete, which has helped us to grow into a full-service provider for the construction industry. We now have the skills and expertise to provide a wide variety of tangible solutions to our clients. One example is our specialist Concrete Design/Build services, in which we hire a structural engineer and work with them during the design process to ensure that our clients get a cost-effective concrete system with their first set of structural drawings.

Builders save time and resources by preventing change orders when value engineering has already been completed. Early on in the process, our design-build team collaborates with other design experts (architect, wood structural engineer, civil engineer, etc.), which can be extremely useful with today’s complex building designs.

Nova SCP can anticipate and quickly respond to any problems with formwork, shotcrete or rebar by shuffling crews to accommodate scheduling.

Concrete Reinforcement

Concrete has a long history of large-scale construction due to its incredible compressive strength; the Romans have used forms in a way that is similar to modern precast manufacturing. Researchers are still studying Roman concrete today to figure out how buildings constructed thousands of years ago have stood the test of time so well.

The Romans, on the other hand, never knew how to strengthen concrete to compensate for its poor tensile strength. Rebar, welded wire fabric, prestressing/post-tensioning, and fiber are the four main methods to strengthen concrete today. The spectacular and versatile uses of concrete that we associate with modernity are made possible by these technologies.

Steel rods are the world’s oldest method of strengthening concrete, dating back to the 15th century. However, it wasn’t until 1853 that the material was used in a four-story home in Paris by François Coignet. Steel bars embedded in concrete improve the tensile strength of the material, allowing cured concrete to be used in applications such as precast beams and deck plates. This works well not only because of the intrinsic tensile strength of steel, but also because the coefficients of expansion of steel and modern concrete are very similar. The two materials maintain the same size compared to each other as temperature changes cause them to expand and contract, avoiding excessive stress and cracking.

The size or area, weight, and precise placement of bars must all be carefully considered for successful steel reinforcement in any application. Fortunately, this is a well-studied field, and when designing new elements, precast manufacturers have access to detailed specifications, well-developed codes, and equipment.

Concrete Pumping

With “wet-process shotcrete,” a low-slump concrete mix is pumped to the pipeline’s end, where a special “shotcrete nozzle” is attached, using a Concrete Pump. The compressed air introduced by the shotcrete nozzle is injected into the concrete. This compressed air is typically supplied by a 165-185cfm air compressor, which is available separately. The compressed air gives the concrete more velocity, causing it to spray out of the nozzle. The low slump of the shotcrete mix, combined with the high velocity, allows the concrete to be sprayed on cliffs, vertical walls, and overhead.

Any wall thickness and concrete finish can be shotcreted. Basement and parking garage walls are two examples of typical applications. Shotcrete has no limits. Design your custom creation without the constraints of cast-in-place concrete’s constructability and expense. Shotcrete contractor for pools and aquatics that is dependable and of high quality. Make a link with Nova SCP and never look back.

A high-quality construction guarantees that your pool can last as long as possible. Shotcrete may be spread horizontally, vertically, or even upward to adhere and shape to the underside of a ceiling since it is a free form of concrete. This results in extremely strong and watertight structures that can be shaped into any shape. Using a pump, hose, and a specially built application nozzle, shotcrete is applied pneumatically. In a shotcrete application, the cement content is higher and the water content is lower than in a “cast-in-place” application. The mixture produces a dry concrete mix suitable for use on vertical surfaces such as pool walls.

Aside from the obvious construction benefits mentioned below, shortcreting gives the builder and designer more versatility and design imagination.

Shotcrete pools are the best and most watertight when correctly built and installed. As compared to other alternatives such as block-filled walls or reinforced concrete, shotcrete is ideal for extremely fast construction. Since the concrete mixture contains less water, there is less volume change as a result of water hydration, resulting in much less joints in the pool between wall parts than for a cast-in-place wall.

  • Higher compressive strengths than cast-in-place concrete, ranging from 6,000 to 7,000 psi.
  • Any shape or design can be made strong and watertight using the free form application.

The consistency, strength, and integrity of construction materials are ensured by using wet concrete, which is mixed to exacting standards in a factory-controlled environment and trucked directly to the pool site.

And when using shotcrete for pool construction, the contractor must be highly skilled, as is the case for any construction. Shotcrete, when done correctly, produces a much better and watertight pool installation than cast-in-place.

Concrete Finishing

Since the 1960s, shotcrete, specifically the wet mix process, has been used in construction projects. Shotcrete may be used for a variety of purposes, including swimming pools, basement walls, and slope stabilization, to name a few. The visual appeal of the surface finish is one of shotcrete’s fundamental weaknesses. When left in its natural state, or ‘gun finish,’ the end result may appear messy and unattractive, particularly when used in large quantities. Furthermore, using inexperienced shotcrete contractors and low-quality materials can result in an eyesore that is difficult to repair.

Shotcrete industry leaders are well aware of the problem and have produced a variety of finishes that are far superior to the traditional gun finish. There are several different levels of finishes available, which are usually achieved by adding an extra step to the previous process, which comes at a cost to the consumer. Steel trowelled, virtual rocks, and colored finishes are just a few of the options, and today we’ll take a closer look at each of them and the processes that go into achieving them on vertical walls.

  • Gun Finish
  • Screed Finish
  • Wood Float & Sponge Finish
  • Steel Trowel Finish
  • Oxides & Pigments
  • Simulated Rock & Block Finish

Shotcrete

Shotcrete, a building method first used in the early 1900s, is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. It is usually supported by traditional steel rods, steel mesh, or fibers.

Shotcrete is a generic term that refers to both wet-mix and dry-mix forms of the material. Shotcrete refers to wet mix in pool construction, while gunite refers to dry mix. These words are not synonymous in this sense.

Owing to the force with which shotcrete is expelled from the nozzle, it is both mounted and compacted/consolidated at the same time. It can be sprayed on every kind of surface, including vertical and overhead areas.

Pumping a previously prepared concrete, usually ready-mixed concrete, to the nozzle is the process for wet-mix shotcrete. To propel the mixture onto the receiving surface, compressed air is added at the nozzle. When compared to the dry-mix process, the wet-process technique produces less rebound, waste (when material falls to the floor), and dust. The most significant benefit of the wet-mix process is that all of the materials are combined with the required water and additives, and greater quantities can be put in less time than dry-mix concrete.

Shotcrete machines are available that monitor the entire process and make it extremely quick and simple. Wet spraying may be done manually or mechanically, but wet sprayed concrete is traditionally applied by machine. Because of the high spray outputs and wide cross-sections, the work must be automated. Working with wet mixes necessitates the use of concrete spraying systems with duplex pumps. Unlike traditional concrete pumps, these systems must also provide a concrete flow that is as consistent as possible, and therefore continuous, in order to ensure homogeneous spray application.
