Gabions are manufactured from dimensionally stable panels of mesh that are formed by welding transverse and longitudinal wires at each and every intersection to form a grid. The gabion box is then part assembled by hinging the face, back, sides and internal diaphragms to the base panel and the lid to the rear panel with ‘C’ rings or clips. The units are transported to site flat packed with lacing wire as standard for on site erection.
Welded Mesh Gabion 39 System: Standard gabions
Welded mesh Gabion 39 System is available in mesh aperture 76.2mm x 76.2mm and in the following specifications to the nominal dimensions stated below. Other non-standard mesh apertures are available on request.
Welded Mesh Gabion 27 System: Modular welded mesh gabions
The Gabion 27 System comprises of modular welded mesh units that are sub-divided into 685mm cells along the length of the cage. The base of the gabion forms the lid of the unit below. The base is extended by fixed dimensions on one face to allow for a predetermined stepping arrangement at each course. The base on the other face is flush, allowing for a flush faced wall to be constructed if required or coursing with a combination of flush and stepped faces.
Woven mesh gabions and mattresses
The mesh fabric for all these products is formed by weaving adjacent strands of wire by twisting them through one and a half turns at intervals, forming a hexagonal shaped mesh. The ends of the mesh wires are wrapped around a heavier transverse edge wire to form the panels. The tensile strength of the mesh in the direction of the weave is greater than across the weave. The gabion box is manufactured from a main panel that forms the face, base, rear and lid of the unit. The side panels and diaphragms are then jointed to the base section of the main panel. The unit is then folded flat for transportation. On site, the unit can be opened out into the required position and the sides, diaphragm and end panels are rotated vertically. The vertical joints are formed by a continuous lacing operation with the wire supplied or with ‘C’ rings to form the box shape.

Japanese knotweed control
Japanese Knotweed is recognised by the Environment Agency as the UK’s most invasive species. Knotweed can grow up to 10cm a day. It is a statutory offence to cause or allow Japanese knotweed plants to grow in the wild, whilst great care must be taken over disposal, as waste regulations categorise all of the plants and contaminated soil as controlled waste. Adjoining owners may take civil action seeking damages due to the spread of Japanese knotweed onto their property. Keyline has a range of tried and trusted costeffective environmentally aware japanese knotweed solutions, to fit clients’ timescales, budgets, and site specific requirements, as well as meeting all regulations. Solutions can also be applied to Himalayan Balsam, Giant Hogweed, and most other imported invasive plants.
