Woven Mesh Systems
Enviromesh are the Uk's leading name in woven and welded mesh gabion systems. The company's personnel have over 40 years experience in the design, sales, manufacture and on site support in the global wire mesh and gabion construction industry.
Their experience and technical knowledge provide a new level of insight and development for both the Civil Engineering, Architectural and Domestic sectors of the market.
GABIONS
The mesh fabric 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.
Once assembled the gabions are filled with stone or rock and the lid secured to form a monolithic structure.
GABION MATTRESSES
Gabion mattresses are box units where the plan area is large compared to its height. Each unit is subdivided into compartments normally to give cells 2mx1m in plan.
Typically standard sizes are 3mx2mx0.3m and supplied in a Zinc or PVC/Zinc coated wire.
The units are laid on the bed of rivers. Once filled with stone or rock and the lid closed, they form a blanket erosion control system.
Gabion Mattresses are also used to provide underscour protection to retaining structures.
ROCK NETTING
Rockfall protection netting is a hexagonal woven wire mesh, supplied in rolls 2m wide and 25m in length.
Rock netting is draped down rock escarpments, secured at the top to guide falling rocks safely to the toe of the escarpment.
Alternatively it can be pinned back to the rock face to retain loose spalling rocks in place.
A woven mesh is preferable to a welded mesh as it can follow the contours of the rock face.
