This strengthening technique is implemented by transporting a dry mix of cement and aggregate through a pipe at high speed using compressed air, then adding water to the nozzle and spraying it onto a given surface.
With over 100 years of history, dry shotcrete is a proven technology that is considered one of the most effective techniques for structural repairs and reinforcement work, when implemented by specialists.
Tunnels & culverts
Port & Waterway structures
Pathologies encountered by our clients
Lack of concrete cover to protect rebars, lack of reinforcing bars, insufficient cross section, etc
Concrete carbonation, concrete chloride contamination, masonry deterioration, etc
Damage to the concrete surface due to hydrocarbon fires, impacts, hydraulic abrasion, etc.
When the level of service loads is increased, dry-sprayed concrete can be used to strengthen the structure by increasing the reinforced concrete sections.
Why choose the dry shotcrete technique for your project?
01. Very high adhesion
02. Very high strength
03. Almost no formwork required
04. Long conveying lengths
05. Applicable to all types of structural elements
06. Formulation according to the application
07. The result is considered monolithic
08. Covered by multiple standards
From structural analysis to implementation
we help solve your problems
Before repairing or reinforcing, the condition of the structure and its load-bearing capacity must be assessed. Freyssinet can help with the diagnosis: visual inspection, destructive and non-destructive testing, stress analysis, etc.
the right solution at the right place
We assist you in developing a repair strategy or in checking its feasibility. Our engineers analyse the project specifications, draw up plans and calculation notes. They select the appropriate equipment and define the production programme.
Guaranteed results at execution:
a complete control of the implementation
The composition of the dry mix, the power of the equipment and the skills of the nozzlemen are essential to deliver a quality job. The Foreva Shotcrete solution is applied by our experienced nozzlemen, certified in-house under a dedicated quality charter.
