Mix design and aggregate grading
Material composition and mix condition before transport and spraying.
Shotcrete for mining
Shotcrete for mining with technical support for wet-mix and dry-mix applications
TREGA combines admixtures, fibers, complementary materials, and technical support to select and apply shotcrete solutions according to the mix, water, substrate, dosage, equipment, and actual operating conditions.
Technical criteria
Performance is defined in the operation, not only in the technical data sheet
In shotcrete, the same product category can perform differently when the mix, aggregate grading, water presence, substrate preparation, thickness, dosage, equipment, or application method changes.
That is why selection should not be based only on the admixture name or a specified strength. TREGA starts from the actual application conditions to determine which combination makes technical sense for the operation.
Critical variables
What we review before defining a shotcrete solution
The technical assessment focuses on variables that can affect pumpability, rebound, adhesion, and final performance.
Water and substrate
Water presence, preparation, and condition of the surface where shotcrete will be applied.
Dosage and equipment
Relationship between product, dosage, pumping, spraying, and the equipment configuration available on site.
Application and thickness
Application method, required thickness, and conditions that must be maintained during placement.
Application methods
Wet-mix and dry-mix shotcrete require different technical decisions
TREGA works with both methods. Selection and adjustment must respond to the available system, the material, and the application conditions.
01
Wet-mix
The mix, transport, and spraying process must work as one system
- Review of mix design and aggregate grading.
- Dosage and compatibility with the pumping process.
- Substrate and application conditions.
- Field performance follow-up.
02
Dry-mix
Performance depends on material, water, and application control
- Material condition and aggregate grading.
- Water availability and control during application.
- Equipment and spraying method.
- Review of rebound, adhesion, and final result.
What TREGA integrates
Product, technical criteria, and follow-up within one solution line
The solution is built around what the application requires, without separating product supply from the variables that determine performance.
Admixtures
Technical selection according to method, mix, dosage, and application conditions.
Fibers
Integration of fibers into the shotcrete solution according to application requirements.
Complementary materials
Supporting materials used to complete the solution when the technical condition requires them.
Technical support
Assessment, application support, and follow-up to review actual field performance.
How we work
The recommendation is built from the actual application conditions
Review the condition
We identify mix, substrate, equipment, method, and application variables that can affect the result.
Define the combination
We select the solution based on the variables that actually condition the process.
Support the application
Technical support makes it possible to compare the recommendation with observed field performance.
Follow up
Follow-up helps identify adjustments and prevents changing conditions from invalidating the initial selection.
Observable performance
When performance changes, review the condition before increasing product dosage
Changes in pumpability, rebound, adhesion, or final performance can indicate that a system condition has changed. The objective is to identify that variable before compensating only with more dosage or more intervention.

Shotcrete: criteria to review before selecting a solution
Direct answers about the scope of TREGA’s technical shotcrete line.
Does TREGA work with both wet-mix and dry-mix shotcrete?
Yes. TREGA works with both methods and adjusts product selection and technical support to the application conditions.
What variables are reviewed before defining a solution?
Mix design and aggregate grading, water presence, substrate condition, thickness, dosage, equipment, and application method.
Does performance depend only on the admixture or specified strength?
No. The result can also change when the material, water, substrate, thickness, dosage, equipment, or application changes.
Does TREGA provide technical support for selection and application?
Yes. The service line combines supply with technical assessment, application support, and follow-up according to operating conditions.
