HESLY GABION INTRODUCTION

At HeslyGabion®, we manufacture and supply three types of gabion products including HESCO Barriers, Double Twisted Mesh Gabion, Welded Mesh Gabion.

HESCO Bastion Barrier

Brief introduction of Hesly HESCO bastion barrier

We start to design and produce HESCO concertainer since 2005, which required by one of our customer from Saudi Arabia. since then we became the first factory who is capable of manufacturing HESCO barrier.


 

HESCO Bastion Barrier in the world

The Hesco bastion barrier is both a modern gabion used for flood control and military fortification and the name of the British company that developed it in the late 1980s. It is made of a collapsible welded wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent dike or barrier against explosions or small-arms. It has seen considerable use in Iraq and Afghanistan.

Originally designed for use on beaches and marshes for erosion and flood control, the Hesco Bastion quickly became a popular security device in the 1990s. Hesco barriers continue to be used for their original purpose. They were used in 2005 to reinforce levees around New Orleans in the few days between Hurricanes Katrina and Rita. During the June 2008 Midwest floods 8,200 metres (5.1 mi) of Hesco barrier wall were shipped to Iowa. In late March, 2009, 10,700 metres (6.6 mi) of Hesco barrier were delivered to Fargo, North Dakota, USA to protect against floods.

Assembly


 

Assembling the Hesco bastion entails unfolding it and filling it with sand, soil or gravel - usually using a front end loader. The placement of the barrier is generally very similar to the placement of a sandbag barrier or earth berm except that room must generally be allowed for the equipment used to fill the barrier. The main advantage of Hesco barriers, strongly contributing to their popularity with troops and flood fighters, is the quick and easy setup. Previously, people had to fill sandbags, a slow undertaking, with one worker filling about 20 sandbags per hour. Workers using Hesco barriers and a front end loader can do ten times the work of those using sandbags.

The Hesco barriers come in a variety of sizes. Most of the barriers can also be stacked, and they are shipped collapsed in compact sets. Example dimensions of typical configurations are 1.4m x 1.1m x 9.8m (4’6” x 3’6” x 32’) to 2.1m x 1.5m x 30m (7’ x 5’ x 100’).

A new system of Hesco Bastion concertainer developed specially for military use is deployed from a container, which is dragged along the line of ground where the barrier is to be formed, unfolding up to several hundred metres of barrier ready for filling within minutes.

 

 

 

 

 

Double Twist Mesh Gabion/Hexagonal Mesh Gabion

HESLY hexagonal mesh Gabions are rectangular wire mesh baskets filled with rock at the project site to form flexible, permeable, monolithic structures such as retaining walls for commercial, industrial and road projects. When gabions are filled with stone they become large, flexible building blocks from which a broad range of structures can be built. Gabions are also used for erosion control, bank stabilization, channel linings, and weirs.

The main advantages of gabions are their strength and flexibility. Their wire construction can tolerate differential settlement without fracture. Hydrostatic pressure does not build up behind the gabion units because of their permeable nature. This ability to combine drainage and retention functions makes gabions ideal structures for slope stabilization.

The strength of HESLY's gabions comes from a double twisted hexagonal steel wire mesh which is reinforced by selvedges of heavier wire running along the edges and by transverse diaphragms. The double twisted wire will not unravel, even when the gabion is cut.

HESLY gabions are easily assembled, and require no specialized labor; nearby rock can be used for fill. 

HESLY gabions are available with different levels of protective coating for durability. Such as: Hot Dipped Galvanized;Galfan (Al 5%-Zn alloy & Al 10%-Zn alloy); PVC coated.

 

Welded Mesh Gabion

HESLY is a manufacturer of pre-assembled welded wire mesh gabions and gabion mattresses. Welded wire mesh means that each point of contact in the grid is actually welded to form a very rigid connection, making this type of gabion indispensable in achieving that perfectly flat, sharp appearance a structure should maintain.

Welded wire mesh baskets and mattresses are used in applications which require earth retention or soil stabilization. Made from either galvanized or PVC coated mesh, the finished wall is aesthetic and cost effective.

Pre-assembled gabions by HESLY provide a shape control that is far superior to that achieved with other types of baskets, such as twisted or woven wire fabrics. In addition, HESLY welded mesh gabions install at a considerably faster rate than woven wire baskets. Studies have shown that welded wire baskets install at a rate that reduces labor costs by at least 50%.

 

Double Twist Hexagonal Mesh Gabion 

The Hexagonal Mesh Gabions are wire fabric containers, uniformly partitioned, of variable size, interconnected with other similar containers and filled with stone at the site of use, to form flexible, permeable, monolithic structures such as retaining walls, sea walls, channel linings, revetments and weirs for earth retention. 

Soil erosion is an ever present problem and gabions have proved to be a lasting solution around the world. The earliest known use of gabion-type structures was for bank protection along the Nile River during the era of the Pharaoh. In the subsequent 7,000 years since its initial use by the Egyptians, the gabion system has evolved from baskets of woven reeds to engineered containers manufactured from wire mesh. The lasting appeal of gabions lies in their inherent flexibility.

Gabion structures yield to earth movement but maintain full efficiency and remain structurally sound. They are quite unlike rigid or sem-rigid structures which may suffer catastrophic failure when even slight changes occur in their foundations. Highly permeable, the gabion structures act as self draining units which "bleed" off ground waters, relieving hydrostatic heads. Interstitial spaces in the rock fill dissipate the energy of flood currents and wave action. 

Efficiency in gabion structures, rather than decreasing with age, actually increases. During early periods of use, silt and vegetation will collect with the rock fill to form a naturally permanent structure and may be used to remove solid pollutants or "floatables" from the water.

Gabions and mattresses may be purchased as as assembled baskets, as unassembled panels, or in rollstock form.  Rollstock may utilized to build continuous gabion structures up to 300 feet in length or mattresses up to 150' in length.
