GABION BASKET APPLICATIONS
Gabion baskets are used in many situations, including the stabilization of earth movement and erosion, river control, reservoirs, canal refurbishment, landscaping and retaining walls. They can be manufactured in welded mesh or woven wire. Welded mesh gabions are faster to erect and do not need tensioning. This allows them to keep their shape, to be free from bulges and depressions and fit easily against the wall. It is possible to cut holes in them if needed to pass pipes etc through and they can be machine filled.
We also sell gabion baskets to the public for bespoke or small projects.
CUSTOMISABLE GABION BASKETS
Gabion baskets are customisable. You can sit them within each other to give a curved effect, for home garden use. The picture to the left of this is a great example of our gabions displayed at the Chelsea Flower Show. As you can see the gabions can be planted in to soften edges. If used for seating areas, slabs can be cut and placed on top of the wall to make a striking feature. When used for landscaping purposes, their versatility is limited only by imagination. For example, wine bottles have been used as an infill, or a recent trend is to half fill with stones and half fill with timber logs (please note this kind of fill is only suitable for decorative and not structural purposes). FMM can insert a partition at the front of the gabion baskets so that expensive stone can be used at the front, whilst the rest of the gabion can be filled with lower quality aggregate. We can also offer bespoke gabions for specific designs, from curves to steps.
An example of a domestic project is shown below. In this case, over the course of a weekend, a family dramatically improved their back garden, clearing away an old fence and installing a smart gabion wall. Gabion baskets are easy enough to install that no experience is necessary to get a good result.
WELDED MESH GABIONS
Welded Mesh Gabions are manufactured from Galfan Wire or triple life coated.
3" x 3" (76.2mm x 76.2mm) x 3, 4 or 5mm Galfan coated (95% Zinc 5% Aluminium for up to 4 times the life of a galvanised finish) welded mesh Gabion baskets wire as per EN 10218-2. All mesh panels used to produce our baskets are European sourced and conform to EN10244-2 with a tensile range of 540-770N/mm2, steel grade 0.10% Carbon max, Weld sheer strength minimum 75% of the tensile strength of the wire.
We also supply gabion baskets in the same specification as the above but in Green Nature coated. Full specification 3” x 3” (76.2mm x 76.2mm) x 2.77/3.22mm 4life “4 times the life of a galvanized finish", then Nature coated welded mesh. Nature coated to an overall diameter or 3.22mm, average coating thickness is no less than 0.25mm, Nature" coating is based on PE and is superior to PVC in UV resistance or behaviour in cold temperatures. Main advantage is the environmental aspects including storage, use and recycling. Apart from that "Nature" is comparable to PVC. All mesh panels used to produce our baskets are European sourced from a European supplier IS0 9001, ISO4001, OHSAS 18001 registered and conform to EN10244-2 with a tensile range of 540-770N/mm2, steel grade 0.10% Carbon max, Weld sheer strength minimum 75% of the tensile strength of the wire.
Plastic coated units are most suitable for coastal projects. The Gabions comply with the Department of Transport White Book specification, as detailed in section: 6.26/4, and amended August 1994.
Gabion boxes and Mattresses are made from 76.2mm x 76.2mm nominal (3" x 3") Welded Mesh, divided by diaphragms at 1 metre centres where necessary with wire diameters 3mm, 4mm or 5mm.
3mm diameter wire is used on lower retaining walls, 4mm diameter wire on medium to high retaining walls and the heaviest 5mm wire for the highest structures. FMM also fabricate our gabion baskets in mixed diameter wire panels for clients where cost saving is important.
Gabion baskets used as cladding can provide an attractive finish to buildings, walls and many other situations. Gabions of 0.3m to 0.5m are generally used and need to be attached to the existing building using clamp bars. At heights of 4 to 5m 4mm dia wire baskets should be used and above this height 5mm dia wire. The baskets are supplied with internal diaphragms, dividing the basket into partitions of no more than 700mm square.
Gabions have now become an important feature in many situations, and the construction of thin walls or cladding made from narrow depth gabions, have become popular where there isn't room for a retaining wall that follows the standard designs. As they require vertical faces and are narrow depth, extra support to provide stability is necessary. This can be provided by using metal or concrete posts at regular intervals inside the gabion basket.
We can't advise on the post specification or the spacing, as it does not follow our standard designs that have been calculated by a geotechnical consultant. The posts are doing the retaining, not the baskets. You will need to contact a geotechnical consultant for the design.
Fine Mesh Metals supply a range of gabion baskets specifically for this purpose, made from 4mm dia wire to provide the added strength required to prevent deforming of the face, with minimum basket depth of 0.3m, preferably 0.5m.
The example in the image is for reference purposes only, it's for short walls and has not been desiged or approved by a structrual engineer.
Below are the standard sizes we stock. Though we are able to produce any size. It is best to keep to the sizes specified to minimise costs. If you do require a certain height, try to keep to combinations of 75mm, the mesh size to give full squares.

Mattresses are useful when trying to avoid erosion in streams. The mattress goes into the river and underneath a gabion wall to stop the river undercutting the wall at the edge where the water speed is fastest.

Also available with 50 x 50 x 3mm faces for smaller stone infill
Weight of Filling Materials
The stone fill should be in accordance with the engineers specification and needs to be a hard and durable material. The gabion/mattress fill should be not less than 100mm and generally not greater than 150mm with 90% being retained on a 100mm diameter ring. For a more attractive finish hand packing to the face is required prior to machine filling.
