A technical solution tailored to ground constraints

What is shotcrete?

Shotcrete involves applying concrete at high velocity directly onto a surface, without formwork. This technique strengthens, protects and stabilises rock faces or unstable ground. Used on its own or alongside other techniques (soil nailing, micropiles, retaining works), it offers rapid execution, optimal adhesion and durable strength.

Shotcrete, also known as sprayed concrete or gunite, is a technique of spraying concrete by dry or wet process, applied under pressure so that it perfectly follows the shape of the substrate. This method is particularly used for slope strengthening, rock-face protection, retaining structures and areas requiring rapid intervention without formwork.

Why choose shotcrete for your works?

Shotcrete offers many advantages for special foundation and stabilisation works.

A formwork-free solution

The concrete is sprayed directly onto the substrate, for rapid execution, even on complex shapes.

Excellent adhesion

Spraying under pressure ensures optimal adhesion to the ground or rock face, durably strengthening the structure.

Rapid, safe execution

The technique allows fast intervention while ensuring the stability and safety of the site.

Ideal for difficult access

Shotcrete is perfectly suited to sites on slopes, at height or with restricted access.

Expertise in special works

Every application is studied to suit the nature of the substrate and the site constraints.

A durable, protective solution

Shotcrete protects rock faces against erosion and extends the service life of structures.

Frequently asked questions

What exactly is shotcrete?

Shotcrete is a technique of spraying concrete under pressure directly onto a surface, without formwork. It strengthens, protects and stabilises rock faces, slopes or existing structures.

When is shotcrete used?

For ground strengthening, rock-face protection, retaining, slope stabilisation or securing excavations, particularly on constrained sites.

What is the difference between shotcrete and traditional concrete?

Shotcrete requires no formwork: it is applied directly onto the substrate, for better adhesion and great adaptability to complex shapes.

Is shotcrete compatible with nailed walls?

Yes. It forms the facing of the nailed wall and provides protection, stability and durability once the nails are in place.

Can shotcrete works be carried out on difficult-access sites?

Yes. It is perfectly suited to sites on slopes, at height or in confined spaces, in particular in combination with rope-access works.

What is the difference between the dry and wet process?

The dry process sprays a dry mix that is wetted at the nozzle; the wet process sprays concrete that is already mixed. Sirianni Travaux selects the method best suited to each project.
