Mesh Reinforcement

The importance of mesh reinforcement in structures.

For all types of property development projects, mesh reinforcement is used in construction to reinforce the structural integrity and enhance the durability of any structure and vastly improve its tensile strength to prevent cracks or premature structural failure due to structural stresses or vibrations. 

Mesh reinforcement can greatly minimize the appearance of cracks but is recognized that it will not prevent cracks from appearing in concrete. Mesh reinforcement prevents premature structural cracks from appearing on any concrete structure which can adversely compromise its long-term durability and stability. It allows hardened materials like concrete to prevent cracks from spreading and weakening any structure.

When is mesh reinforcement required?

For any heavy concrete structure planned to be located on soft or uneven ground, adding mesh reinforcement is generally recommended to prevent any premature cracking which can result in the overall weakening of a structure due to uneven weight distribution, vibrations, and soil movements. For light-duty structures like pedestrian pathways or an ordinary shed floor, mesh reinforcement is generally not required.

While something like a domestic carport, driveway, or garage floor mesh reinforcement is generally not required but is commonly recommended to be added since vehicles can produce uneven weight stresses which can result in the premature cracking of concrete. For commercial driveways and vehicle parking areas that are repeatedly used by heavy vehicles and equipment, mesh reinforcement is always added to preclude the chances of premature concrete failure due to constant weight stresses and vehicular vibrations. 

Whenever any concrete structure is required to be strengthened, mesh reinforcement is used since the need for additional strength support in concrete varies with each specific concrete application with mesh reinforcement adding greatly to its long-term stability and durability.

Is mesh reinforcement required for concrete? 

Any concrete structure like pathways or driveways that are expected to undergo repeated pedestrian or vehicular traffic, any load-bearing structural walls, and other foundational structures will always require the extra strength provided by mesh reinforcement to concrete to provide support and add extra strength against premature cracking from repeated stress and vibrations. 

Mesh reinforcement ensures the long-term structural strength of any concrete structure and it is commonly accepted that while some areas of a structure might not require any mesh reinforcement to be added it is still generally recommended no matter the size or scale of any concrete structure such as in public works projects.

Any part of a structure that is expected to encounter a heavy workload such as repeated bending and vibrational stresses will always require mesh reinforcement to prevent concrete from weakening and cracking under long-term heavy use.

Mesh reinforcement strengthens concrete.

While reinforcing bars are typically used to encompass the edges of large concrete slabs to prevent their edges from prematurely cracking under stress. Mesh reinforcement, on the other hand, is often paired with reinforcing bars depending on specific structural strength requirements.

Mesh reinforcement comes in various sizes and thicknesses to meet specific concrete strength requirements and is made up of heavy-duty wires welded or wired together into a flat reinforcing sheet with the wires forming a grid-like pattern which allows the mesh reinforcement to better adhere and grip with the concrete with the drying process of concrete sealing off the mesh reinforcement from exposure to the elements which prevents it from corroding and rusting under long-term use. Exterior walls and exposed structural foundations and columns are ideally suited for adding mesh reinforcement.

Do all concrete construction projects need mesh reinforcement? 

Long-term use projects such as in public works, where concrete is required to be stronger than it needs to be, will always require to have mesh reinforcement and on almost all modern concrete public construction project.  Mesh reinforcement is generally added and is always necessary to ensure a structure’s long-term strength and durability. It ensures that all concrete structures are stable, able to withstand repeated stresses, and provide the utmost long-term reliability and safety.

Mesh reinforcement.

Mesh reinforcement is widely available in all shapes, sheet sizes, and thicknesses for use in specific applications. Mesh reinforcement have grids that are square to rectangular, welded or tightly wired together, brick or ladder meshed. Very specialized mesh reinforcement is also available that meets very specific structural strength requirements for structures intended to bear high stresses and very high loadings.

The common, and readily available, mesh reinforcement types.

The most common mesh reinforcement types are the:

  • Square mesh reinforcement.
  • Rectangular mesh reinforcement.
  • Trench mesh reinforcement, and
  • Ribbed mesh reinforcement.

The square-mesh reinforcement.

The square-mesh reinforcement is a general-purpose concrete reinforcement type that is used for strengthening light load-bearing flat concrete slabs and walls. The square mesh reinforcement is the most common and widely available mesh reinforcement shape and comes in many sheet sizes in either standard dimensions for light-duty, low-stress concrete applications or specially manufactured to meet specific concrete strength requirements.

The rectangular-mesh reinforcement.

Rectangular mesh reinforcement is used when the strength dimensions of a structure are required to have extra one-directional support. It is generally used when a single directional strength is required for structures like very wide and high-load-bearing walls and floors that are also too long, too tall, or too heavy and expected to undergo repeated bending and vibrational stresses.

The trench-mesh reinforcement. 

The trench mesh reinforcement is generally used for strengthening concrete footpaths, rock-climbing walls, non-load-bearing brick walls, and any other narrow structure that is only expected to undergo very light stresses. The trench mesh reinforcement is also used specifically for strengthening the side walls of trenches used in residential and commercial drainage applications. Trench mesh reinforcement is also commonly used in the construction of borders on residential and commercial foundations or for strengthening trenches used as property bordering lines in homes and commercial establishments.

The ribbed-mesh reinforcement.

The ribbed mesh reinforcement has high bond strength in concrete and provides very superior and long-lasting crack prevention by making concrete structures more flexible which results in its resistance to long-term bending and vibration-induced stress cracks. 

The ribbed mesh reinforcement is very versatile in its uses and can be embedded with other shapes and sizes of mesh reinforcement materials, from the square to the trench mesh reinforcement types. Adding ribbed mesh reinforcement is also the most common method for greatly increasing the strength of circular concrete structures that are expected to undergo tremendous vibrational and bending stresses like bridge supports and structural support columns.
