Shotcrete & Gunite Contractor in Florida
Florida’s soil, water, and weather conditions create demanding construction and repair environments. High water tables, sandy and clay soils, storm exposure, coastal corrosion, and shifting foundations can all affect concrete structures over time. Consel Inc. specializes in gunite, or dry-mix shotcrete, for residential, commercial, municipal, and industrial projects in Florida that require strong, adaptable concrete placement.
Shotcrete is concrete or mortar applied pneumatically through a hose at high velocity. Because the material is sprayed onto the surface instead of poured into traditional forms, it is useful for curved structures, thin sections, vertical surfaces, overhead repairs, bridges, tanks, sewer systems, lift stations, wastewater treatment plants, tunnels, retaining walls, canals, pools, and complex structural repairs.
Since 1983, Consel Inc. has provided specialty construction repair services across Florida and the broader Southeastern United States. With more than 40 years in business, a BBB A+ rating, Florida CGC license #CGC1529641, and notable project experience involving NASA launchpads, theme park rollercoasters, and municipal tunnels, Consel brings proven field experience to complex concrete work.

Gunite Services for Residential and Commercial Projects
Consel works with homeowners, property managers, general contractors, engineers, municipalities, industrial facilities, and infrastructure clients. As a gunite & shotcrete contractor in Florida, Consel can support both new construction and repair projects where conventional concrete placement may be inefficient, impractical, or limited by site access.
Residential applications may include pools, retaining walls, seawalls, slope stabilization, decorative rockwork, drainage structures, and repairs to cracked or deteriorated concrete. Commercial and municipal applications may include structural concrete repairs, tunnel lining, canals, utility structures, industrial facilities, water-retaining structures, bridges, tanks, sewer systems, lift stations, wastewater treatment plants, and infrastructure components.
Shotcrete is especially valuable where the structure has an irregular shape, limited access, or a vertical or overhead surface that would be difficult to form and pour. Depending on the project, shotcrete may be combined with helical piers, concrete injection, or grouting as part of a broader repair plan.
How Shotcrete Works
Every shotcrete project starts with the same priority: proper evaluation, preparation, and application. The quality of the finished structure depends on the mix design, substrate preparation, crew experience, nozzle technique, curing, and project conditions.
Site Assessment
Before application begins, Consel evaluates the site conditions, structure type, repair goals, access limitations, existing concrete condition, water exposure, and project requirements. For engineered work, the project may involve specifications, drawings, reinforcement details, compressive strength requirements, and inspection criteria.
For Florida projects, site assessment may also consider high water tables, stormwater exposure, salt air, corrosion risk, erosion, and soil movement around the structure. For infrastructure projects such as wastewater treatment plants, lift stations, and sewer systems, assessment also includes evaluating chemical exposure, hydrogen sulfide deterioration, and the structural demands of constant water contact.
Surface Preparation
Shotcrete performance depends heavily on proper surface preparation. Existing concrete may need to be cleaned, chipped, roughened, or otherwise prepared to create a sound bonding surface. Loose material, deteriorated concrete, debris, contaminants, and active water intrusion should be addressed before placement.
If reinforcement is required, steel, mesh, anchors, dowels, or other embedded elements may be installed before application.
Mix Selection: Wet-Mix or Dry-Mix
Shotcrete can be placed using either a wet-mix or dry-mix method. The right method depends on the project size, site conditions, application type, access, finish requirements, and engineering specifications.
Shotcrete Application
During application, the shotcrete material is delivered through a hose and applied to the surface with controlled air pressure. The nozzle operator places the material in layers, building the required thickness and consolidating the material against the surface or reinforcement.
Proper nozzle distance, angle, velocity, and sequencing are important for reducing rebound, improving compaction, and achieving the intended strength and bond.
Shaping and Finishing
After placement, the shotcrete may be cut, shaped, trimmed, floated, or finished depending on the project. Structural repairs may require a specific profile, while pools, canals, retaining walls, or architectural features may require more detailed shaping.
Curing and Quality Review
Curing helps the shotcrete gain strength and durability. Depending on the project, the work may also require inspection, testing, documentation, or coordination with engineers, owners, and general contractors.
Wet-Mix Shotcrete
With wet-mix shotcrete, the concrete or mortar is mixed with water before it enters the delivery hose. Compressed air is used at the nozzle to project the material onto the surface.
Wet-mix shotcrete is often used for larger-volume projects, structural repairs, walls, tunnels, canals, and applications where consistent mix quality and production efficiency are important. It can be useful when the project requires controlled material proportions and steady placement.
Common wet-mix applications include:
-
- Tunnel lining
- Structural concrete repair
- Retaining walls
- Canal linings
- Water-retaining structures
- Commercial and municipal projects
- Large pool structures
- Vertical and overhead repairs
Dry-Mix Shotcrete
With dry-mix shotcrete, also commonly associated with gunite, dry cementitious material is conveyed through the hose, and water is added at the nozzle. This method allows the nozzle operator to control the water content during placement.
Dry-mix shotcrete can be useful for smaller projects, repairs, detailed shaping, intermittent work, and applications where start-and-stop flexibility is valuable.
Common dry-mix applications include:
-
- Pool construction
- Curved or shaped structures
- Small structural repairs
- Overhead or vertical patching
- Architectural features
- Irregular repair areas
- Limited-access placements
Shotcrete vs. Gunite
The terms “shotcrete” and “gunite” are often used interchangeably, but they are not exactly the same.
Shotcrete is the broader term for concrete or mortar applied pneumatically at high velocity. It can refer to either wet-mix or dry-mix application.
Gunite typically refers to the dry-mix method, where dry material is sent through the hose, and water is added at the nozzle.
Both methods can produce strong, durable results when properly designed and installed. The better choice depends on the project. A pool, repair area, tunnel, canal, retaining wall, or commercial structure may require different equipment, mix design, and application technique.
As a shotcrete contractor in Florida, Consel can evaluate the project and determine whether wet-mix shotcrete, dry-mix shotcrete, gunite, grouting, or another specialty method is appropriate.
Types, Uses & Advantages of Gunite in Florida
Gunite is valued because it can create dense, durable concrete on surfaces that are difficult to form, pour, or access. It is widely used for both repair and new construction across residential, commercial, and infrastructure applications.
Wastewater Treatment Plants
Wastewater treatment plants are among the most demanding environments for concrete structures. Constant water exposure, hydrogen sulfide gases, biological activity, and chemical contact accelerate concrete deterioration over time. Gunite can be used to reline, repair, and reinforce tanks, channels, walls, and structural elements within treatment facilities, restoring function and extending service life without full demolition.
Bridges
Bridge structures are exposed to traffic loads, water intrusion, freeze-thaw cycles, and corrosion. Gunite is well-suited for bridge deck repairs, pier rehabilitation, column wrapping, and structural patching where form-and-pour methods would be difficult or inefficient. The dry-mix method allows precise material placement in vertical and overhead positions common in bridge repair work.
Tanks and Water-Retaining Structures
Concrete tanks — including water storage tanks, process tanks, clarifiers, and containment structures — are subject to hydrostatic pressure, chemical exposure, and long-term wear. Gunite can be used to restore interior linings, repair cracks and spalls, and reinforce structural walls in both new and existing tank systems.
Sewer Systems and Lift Stations
Sewer infrastructure and lift stations are exposed to constant moisture, chemical attack, and heavy use. Gunite can be applied to rehabilitate deteriorated sewer walls, manholes, wet wells, and lift station interiors, providing a durable, bond-resistant surface that extends the service life of aging infrastructure.
Tunnel Lining
Gunite is useful for tunnel lining, underground structures, and municipal infrastructure because it can be applied to curved and irregular surfaces. It can help restore, reinforce, or protect structures exposed to water intrusion, soil pressure, and long-term deterioration.
Consel’s project experience includes municipal tunnel work, making this a strong application area for complex Florida infrastructure.
Pool Construction and Repair
Gunite is the most common method used for pool shells because the dry-mix process allows the nozzle operator to shape and control the material as it is applied — ideal for custom curves and freeform designs. In Florida, pools are exposed to soil movement, high water tables, hydrostatic pressure, and storm-related drainage changes. Gunite can be used for new pool construction, structural repairs, and restoration where project conditions require a specialty approach.
Structural Concrete Repairs
Gunite can be used to repair damaged, spalled, cracked, or deteriorated concrete. It is especially useful for vertical and overhead repairs where traditional form-and-pour methods may be slower or more difficult.
Applications may include columns, walls, beams, slabs, foundations, parking structures, utility structures, tanks, and industrial facilities.
Curved and Thin Structures
Because gunite is sprayed into place, it is well-suited for curved, thin, and irregular shapes. It can be used for architectural features, artificial rockwork, pools, drainage structures, canal features, and complex structural elements.
Retaining Walls
Retaining walls in Florida are often exposed to saturated soils, erosion, drainage pressure, and stormwater runoff. Gunite can be used for new retaining wall construction, repair, resurfacing, or reinforcement depending on the project design.
Canals and Water-Exposed Structures
Florida canals, drainage systems, and water-adjacent structures are exposed to constant moisture, erosion, and sometimes saltwater or brackish water. Gunite may be used to line, repair, or reinforce canal walls and related structures.
Limited-Access Areas
Gunite can reduce the need for extensive formwork and can be useful in areas where access is restricted. This makes it practical for certain repair sites, existing structures, steep or irregular areas, and projects where conventional placement equipment cannot easily reach.
ACI and ASA Certification Note
Some shotcrete projects may require specific ACI, ASA, or project-defined qualifications, certified nozzlemen, testing procedures, or inspection standards. Consel Inc. can review the project requirements and coordinate the appropriate field approach, documentation, and qualified personnel where applicable.
If a project specification requires ACI or ASA credentials, confirm those requirements with Consel during the estimating and planning process.
