Prefabricated gabions - reno mattresses


Prefabricated gabions have many advantages compared to the conventional method of constructing the gabions on site out of netting rolls.

They are available ready in the final desired dimensions. This ensures maximum construction security and of course maximum work speed.

They are made of heavily galvanized netting and are available in mesh sizes 8 X 10, 6 X 8 and 10 X 12 with wire diameter of 2,70 or 3,00 mm.

Depending on the project hydraulic data, it is possible to use gabions of smaller than the usual height (i.e. 0,50 1,00 M). Reno mattresses can have heights of 0,17 0,23 or 0,30 M, thus reducing project budget substantially.

Lacing of gabions is no longer done in the conventional way (by use of wire). Now special lacing rings made of steel wire (tensile strength 170 kgs/mm2) are available. These rings are applied using a special pneumatic spenax tool and offer the fastest and safest gabion lacing, thus reducing labour costs.


APPLICATION IN GREECE

Prefabricated gabons have already been used in many big and small hydraulic and anti-flood projects in Greece, for example :
