Woven Mesh Gabion Description

Woven Mesh Gabion baskets or cages and mattresses are purpose designed stone filled wire mesh baskets or cages, filled with stone. The name Gabion is derived from the Italian word gabionne which means “big cage”. Woven Mesh Gabions are an economical, environmental and established solution for structural retaining walls and coastal defences. Designed like for like, gabions are hard to beat on cost and aesthetics when compared to other established retaining wall systems such as reinforced concrete and masonry. This is particularly so for low to medium height retaining walls.

Woven mesh gabions are nowadays usually refered to as the traditional gabion and have been in use for retaining wall construction for a long time and is a tried and tested retaining solution. You may also wish to consider our range of Welded Mesh Gabions (Click for info).

Baskets are manufactured from a triple twist chain link hexagonal woven wire mesh. The triple twisting prevents unravelling in the event of some wires getting cut or damaged. They are also sometimes referred to as just stone filled bastions, cages or baskets.

The pliability and flexibility of a Woven Mesh Gabion basket makes it extremely flexible and tough and the ideal solution for civil engineering applications usually on poor or uneven ground, where some deformation of the basket is expected. The resulting wall also tends to look more natural, giving it a dry stone wall effect. As a result it particularly suits retaining wall applications for river training and coastal defence applications.

Woven Mesh Gabion retaining walls can be designed using the traditional gravity retaining wall concept, or alternatively, they can also be used as the facing element for reinforced earth retaining structures.

Gabion Wire Diameter and Coating Options

We offer Woven Mesh Gabion baskets for sale. Baskets are supplied flat packed and then laced together on site to form the required retaining wall. Prefilled gabions are available on special request. It is recommended that gabions be filled insitu whenever possible.

Woven mesh gabion baskets and mattresses are available with a choice of different wire coatings. Standard coatings are HDG (Hot Dip Galvanised), Alu-Zinc (95% Zn + 5% Al) coated or PVC coated. Alu-Zinc coated baskets are often mistaken for galvanised ones as they look similar but can actually last up to 3-4 times longer under similar exposure conditions. PVC coated cages on the other hand can have a design life expectancy of up to 120 years, depending on exposure conditions. PVC coated gabions should be considered for longer service life requirements and for application near the sea, river or locations where exposure to corrosive chemicals, acids and salts is possible.PVC coated baskets are usually supplied with a grey PVC coating as standard but other colours are available to special order.

Standard wire diameter is 2.7mm, while 2.0mm and 2.4mm are available for certain mesh size combinations. Minimum thickness of PVC coating for woven gabions is 0.5mm.
