Mostotrayd 19

Thanks to TENAX T-BLOCK System the southern section of Saint Petersburg’s Ring Road in Russia has been completed in record time.


The final height of the structure reached 11m with a total wall surface area of 25,000 m2 .


The Tenax Geotechnical Office (Milan) carried out the detailed designs for many of the structures consisting of bridge abutments, wing-walls, approach ramp roads and high retaining walls.


The pre-engineered block wall system proved to be an attractive, economical, and durable alternative to stone or poured concrete retaining walls.


The inherent design flexibility could accommodate a wide variety of site constraints with a pleasing aesthetic appearance.
