APPLICATIONS
Understanding Our Approach
Agriculture - Silo Construction | Reservoir Construction
- Silo Construction
Utilising a single-sided shutter approach, a concrete storage silo can be constructed with great speed, superior quality and reduced costs. Before placing concrete conventionally, think shotcrete. - Reservoir Construction
Sprayed concrete is projected against a single-sided shutter delivering a concrete reservoir with no honeycombing or tie holes impacting the integrity of the reservoir wall. The inherent benefit of the shotcrete method is the creation of a monolithic structure with minimal joints , further enhancing water tightness. With the inclusion of additives such as Penetron Admix or Penetron BioMic, the retaining and durability properties are further greatly enhanced.
Mining - Silo Repairs | Silo Linings | Box Cuts | Portal Linings
- Silo Repairs
Shotcrete is an application of concrete spray used to repair cracks and holes in silo walls and roofs and it strengthens and reinforces weakened or damaged areas. Shotcrete is also useful for waterproofing and, by utilising HSWR (high-strength-wear-resistant) materials, the abrasion or impact resistance of the structure is also greatly enhanced.
- Silo Linings
Shotcrete is commonly used on silo linings to provide a waterproof seal to protect the contents of a silo. Shotcrete is applied in a wet mix form and is then rapidly cured to form a dense and impermeable layer that is highly resistant to abrasion and chemical attack. This layer of shotcrete is perfectly suited to silo linings as it can be applied quickly and efficiently and provides a durable surface that will last for many years.
- Box Cuts
Shotcreting in box cuts is a common practice in the mining industry. Shotcrete is used to reinforce the structural integrity of the walls in the box cut. It is also sprayed onto the surface of a rock wall to reduce the risk of rockfall. Applied in layers, Shotcrete consists of a mix of cement, sand and water depending on the application, the shotcrete is then compacted and reinforced with steel or fibres to increase the stability of the rock wall and improve overall safety.
- Portal Linings
Shotcrete is a sprayed concrete used to line the portals of mines and tunnels. It is a reliable and cost-effective, efficient method of lining large areas of rock or earth. This form of tunnel construction requires less labour than traditional methods and can be used in confined spaces. Shotcrete is also highly durable and resistant to water and other elements. The shotcrete mixture is applied using a nozzle to the walls and ceiling of the tunnel in a controlled manner. Numerous layers can be built up and repeated until the desired lining thickness is achieved.
Water Management - Attenuation Dam Lining | Stormwater Channels |Water Retaining Structures |Reservoir Lining | Reservoir Construction | Channels
- Attenuation Dam Lining
Water attenuation systems, typically made using a reinforced concrete shotcrete lining, are designed to store and attenuate surface water run-off from storm events. The shotcrete lining of attenuation dams provides a waterproof barrier and can also be designed to include a filter layer, such as geotextile or geogrid, to allow for the passage of water while preventing unwanted debris and sediment from entering the pond. The shotcrete lining also provides a durable, long-lasting solution that can withstand large volumes of water.
- Stormwater Channels
Shotcrete stormwater channels are specialised concrete drainage channels designed to quickly and efficiently remove water from a site. They are formed by spraying a high-pressure mixture of cement, water – and sometimes small aggregate or sand onto a prepared surface. Shotcrete channels are commonly used in areas that are subject to flooding, erosion, or other water-related problems. They are resistant to most chemical and environmental conditions and can be designed to fit any need. They are also relatively affordable and easy to install, making them a popular choice for stormwater management.
- Water Retaining Structures
Shotcrete in water-retaining structures is a form of sprayed concrete that is used to form or repair structures that are designed to retain or contain water. Shotcrete is an excellent choice for this type of application as it is a highly durable material that can be easily applied with minimal disruption to existing structures or water sources. Shotcrete is also a cost-effective option for large-scale projects and can be used to quickly patch, repair or form water retaining structures. Shotcrete is also resistant to water absorption and can be used to create structures that are designed to withstand extreme weather conditions and changing water levels.
- Reservoir Lining
Shotcrete is an ideal material for reservoir relining due to its high strength, low permeability, and excellent adhesion to the existing surface. It is also highly resistant to cracking, and can be applied quickly and easily to the existing surface. Additionally, Shotcrete is highly water-resistant and can help to protect the reservoir from further damage due to water seepage. By using shotcrete, the need for expensive and time-consuming formwork is eliminated, making the process more efficient and cost-effective.
- Reservoir Construction
Shotcrete is a construction technique that is often used in the construction of reservoirs and other water-holding structures. It involves spraying a high-pressure stream of concrete onto a prepared surface. This allows the concrete to form a dense, continuous layer that adheres to the surface and provides a strong, waterproof seal. The use of shotcrete in reservoir construction is advantageous as it allows for quicker installation and a more durable, low-maintenance structure.
- Channels
Shotcrete is a material used to line and reinforce channels such as irrigation canals, rivers and streams. It is applied as a sprayed-on concrete, reinforced with steel or fibres or rebar, to protect the channel from erosion and to provide a hard-wearing surface that requires almost zero maintenance. Shotcrete also creates a uniform surface, allowing water to flow evenly and reducing the possibility of damage to the channel.
Civil construction - Lateral Support | Retaining Walls |Concrete Repairs |Erosion Protection | Temporary Support | Permanent Support
-
Lateral Support
Shotcrete lateral support is a type of support system used in excavations, tunnel construction and other areas where there is limited space and ground conditions are unstable. The shotcrete is applied to the surface of the excavation or tunnel and then left to harden into a strong and stable wall or arch structure that will provide necessary lateral support. This type of support system is often used in conjunction with other support methods such as piles, drilled anchors, mesh reinforcement and netting to provide additional strength and stability.
-
Retaining Walls
Shotcrete retaining walls are made by spraying concrete, or a dry mix of sand and cement, onto the surface of an existing wall or structure. The concrete is then left to harden and form a strong retaining wall. This process is used in a range of applications, including flood control, erosion control and soil stabilisation. Shotcrete walls are also often used as a cost-effective alternative to traditional concrete block or poured-in-place retaining walls. Better yet, they are relatively easy to install and are available in a wide variety of shapes and sizes.
-
Concrete Repairs
Shotcrete is a type of concrete repair material sprayed onto a surface using high-pressure air. It is particularly well-suited for repairing concrete surfaces that have been damaged by corrosion, freeze-thaw cycles, weathering, salt attack and other forms of deterioration. Shotcrete is often used to repair concrete foundations, walls and other structures. It can also be used to provide a protective coating for buildings or other structures. Shotcrete is available in a variety of mixes, including lightweight, standard and high-strength varieties.
-
Erosion Protection
Shotcrete is a quick and easy way to protect a vulnerable area. It is a sprayed concrete that is applied directly to the slope where it adheres and forms a water-resistant protective layer against soil erosion. It can be applied in layers and reinforced with steel mesh for added strength. Shotcrete is typically used on steep slopes that are prone to erosion, such as riverbanks, hillsides, and shorelines and it can be used to create a barrier, such as a retaining wall, to further protect against erosion.
-
Temporary Support
Shotcrete is a method of placing a concrete mix. Concrete is pneumatically projected at high speed onto a surface. It is an effective and economic method of providing temporary lateral support in the construction of tunnels, shafts, galleries and other underground works. Shotcrete is applied on a prepared substrate and can be reinforced with steel mesh, steel fibres or steel bars to provide additional strength and stability. The shotcrete mix is designed to have a high strength and low permeability and can be applied in a single layer or multiple layers depending on the specific application. Shotcrete is used for many reasons, the primary being to provide temporary lateral support to the surrounding ground and to create a structural frame for the construction. The shotcrete also offers protection against the surrounding environment, such as water or rock burst. It can also be used to fill and seal voids, reduce the risk of water seepage and provide a solvent-resistant surface.
-
Permanent Support
Shotcrete is a form of concrete that is sprayed onto a surface at high velocity. Given its quick application, shotcrete is often used as a form of permanent support in underground mining and tunnel construction. It is a strong, stable, durable, and economical form of support, that sees it frequently used in slope stabilisation and the construction of retaining walls.

Penetron Admix
Penetron Admix is a special formulation of chemicals that is added to concrete or shotcrete to make it durable. The active ingredients in Penetron Admix are silicates, polymers and other proprietary compounds, which react with the cement particles in the concrete or shotcrete mix to form a crystalline structure that fills in the pores and cracks in the concrete. The outcome is a long-lasting impermeable barrier making it the ideal choice to use in durability, chemical resistant and waterproofing applications such as swimming pools, reservoirs, sewers and underground structures.
-
Pre-bagged Supply
Pre-bagged shotcrete material is a type of concrete that is applied to a surface by spraying it through a hose or nozzle. The dry mix material consists of cement, sand and aggregate. It is a high-strength material that is frequently used in construction projects such as tunnels, silo linings and hard-wearing surfaces. Pre-bagged shotcrete material is typically delivered to the job site in large bags or sacks, making it easy to transport and store. The dry mix is then pre-blended and mixed at the nozzle with water and air to create a wet, sticky mixture that is sprayed onto surfaces. This type of concrete provides a high degree of strength and durability and is often used in applications where quick setting and high strength are key.
