soil nailing by professionAls

All Materials from one company applied to industry standards.

shotcrete

Shotcrete is our passion, whether it is dry- or wet-shotcrete, steep slopes or surface, with our Micro Silica modified mix-design we bring always highest specified parameters for approval.

Soilnailing

With our latest fleet of most modern MARINI drill rigs, LASPARSAN grouting machines and self drilling anchors, we are able to stabilize any slope. To a depth of 15m and a diameter of up to 38mm, SNI loves to drill.

engineering

Provided a proper soil investigation, excavation drawings, SNI can design your slope with a program by DEEPEX, internationally known as the top supplier of geo-programs.

hydroseeding

Hydroseeding is a "new" form of slope protection, to the installed rockfall mesh and geo-membrane SNI sprays a fertilized earth mixed with seeds. In only weeks the seeds will grow and turn the slope into a green surface.
