Gabion Box
Three gabion formats, each with its own published size table, for bank protection that has to flex instead of crack.

Pick the format by what the water is doing, not by what is in stock.
The Problem
Why This Needs A Process
Three different gabion formats solve three different problems, and they are routinely substituted for each other. A box used where a mattress belongs is expensive and overbuilt; a mattress used where a box belongs will not retain height. This is how to choose.
Process
Step By Step
Read the hydraulics
Is the structure retaining height, lining a surface, or being placed in emergency conditions?
Choose the format
Gabion box to retain, Reno mattress to line a bank or channel, sack gabion for emergency and underwater placement.
Size the mesh
Select mesh opening and wire diameter together - they are paired in the table, from 60x80 mm at 2.0-2.8 mm wire to 120x150 mm at 2.0-4.0 mm.
Choose the coating
Heavily zinc coated soft temper steel as standard; PVC coated, or an additional polymer coating over the base coating, in aggressive water.
Plan the fill
Confirm stone size and source; install diaphragms and stiffeners before filling, and secure lids with spiral binders, lacing wire or C rings.
Ship folded
Units fold flat for transport, which cuts freight, and are opened and assembled on site.
FAQ
Erosion Control and Bank Protection Systems Questions
Box, mattress or sack - how do I choose?
Box retains height. Reno mattress lines a bank or channel and is 0.15-0.30 m thick. Sack gabion is cylindrical, filled on site and launched, including under water, for river training and emergency works.
Do I need skilled labour to install them?
No. Simple installation with no special technology needed is one of the stated features, and Reno mattress construction does not require skilled labour because the units are very easy to build.
What about hydrostatic pressure?
The stone fill is permeable, so water seeps through while the soil is retained. No additional drainage is required to relieve hydrostatic pressures.
Will vegetation grow through it?
Yes, and that is intended. Sludge in the stones supports plant growing, and the voids in the rockfill fill progressively with silt, promoting vegetation growth.
