Vibro-base series channels



The new generation of GRIDIRON VIBRO-BASE SERIES vibrocompressed channels is the result of a careful and precise design. It introduces innovation and perfection to the channel sector while keeping costs down and positioning itself on the economic end of the range.
The vibrocompressed concrete, which is obtained from a mixture of riverbed inert materials and concrete, together with vibration and compression productive methods, make the VIBRO-BASE SERIES channels highly resistant to compression (RcK>45N/mm2), to freezing and thawing cycles as well as to climatic and mechanical erosion.
The ductile iron gratings GJS500-7, which are housed directly on the edge of the channels, are locked with a stainless steel screw in order to uniformly distribute the stress created by the passage of vehicles guaranteeing stability and silence .
The classification and control comply with European standard UNI-EN1433:2008.


All the VIBRO-BASE SERIES channels must be installed according to the provided instructions.
To make this operation easier, GRIDIRON has created four recesses on each side of the product that improve anchoring to the support and above all make it possible, with the use of specific equipment, to position it easily, making the application easier and quicker.



The channel closing end caps are made with male-female connections, with a in inner seat that makes it possible to seal them together.
It is recommended to use silicon sealant with neutral cross-linkage (model Sitol Silicon Pavimento-Torggler).




The ductile iron gratings locked to the channel have two raised notches in the lower section, which are inserted in their relative housings on the edge of the channel that prevent their longitudinal movement.
