FAQ

ASSEMBLY

What depth should I plan for my retaining wall?

The depth of a gabion wall is primarily decided according to the height of the wall to be built, but also according to the specifications of your project (type of support, type of soil, applied vertical load, etc.). To get an idea of the depth for a typical retaining wall, apply the following rule: DEPTH=HEIGHT/2 (validation by the experts at GABIO is still essential).

What type of foundation and what thickness should I plan?

A foundation is necessary no matter what type of gabion work is bring done. The type of foundation varies according to your wall. Generally speaking, at a minimum, a foundation should be composed of 300 mm (around 11 ¾ inches) of MG20 compacted to 95%.

TECHNICAL SPECIFICATIONS

What tools are necessary?

Our gabions don’t require any particular tools – a simple pair of pliers is all that’s needed to close the C-shaped metal clips that are supplied separately. Spirals are also supplied with certain gabion orders. These spirals, installed vertically, are required to ensure structural integrity of the gabion.

What are the available gabion formats?

GABIO can manufacture any size of gabion. However, the mesh size must fit for the chosen dimensions, either 75mm x 75mm or 50mm x 100mm. The final dimensions of a panel cannot be more than 2m x 1m.

Is your mesh guaranteed against rust?

GABIO steel mesh and its accessories are protected by Crapal Premium anticorrosion treatment. This coating was developed in Europe by Arcelor Mittal and is made of zinc, aluminum and magnesium. This type of coating offers a corrosion resistance that is eight times higher than hot-dip galvanising that can currently be found on Asian products.  Crapal Premium is the highest level of protection offered on the market, allowing us to offer a 20-year guarantee against corrosion.

FILLING

What size of stone should I use?

The minimum size of stone should be 80 mm (more than 3 ¼ inches) to stop the stone from passing through the mesh. Maximum size depends only on the visual aspect you want and the depth of the work being done. We don’t advise the use of frost-shattered stone, as it doesn’t stack properly.

What quantity is needed to fill a gabion?

Generally speaking, in terms of quantity, you should count around 1.6 metric tonnes of stone for every m³ of gabion.

What other materials can be used?

All kinds of solid materials can be used as fill: wood, flat stones, crushed glass, recycled materials, etc.
