Retaining Walls and Fiberglass Rebar Advantages

Retaining walls are used in various applications to hold back a large amount of soil or sand that would not typically stand at that specific angle, typically a very steep slope or hill. This helps to avoid erosion They are used on roadways, coastal lines, and landscaping. When it comes to coastal lines where soil or eath is on the backside and water on the front side it is called a seawall.

They are one of the most exposed concrete structures as they are prone to salt and water damage. Retaining walls are used on roadways where they can be splashed by water and dirt or along coastal walkways and barriers where the saltwater can eat away at the structure. The weight of the saturated soils behind the walls can also push against and that can cause it to break apart in some cases or have poor drainage solutions.

Fiberglass rebar holds a large advantage over steel rebar when it comes to structures such as retaining walls. Structures can corrode over time which is a chemical reaction between any material and its environment and can cause deterioration of materials. Corrosion-resistant options will save money and time long term especially in structures such as retaining walls that pose a costly risk to tear down after rebar has corroded. Fiberglass rebar is a corrosion-resistant product and will not rust even in harsh environments such as salt, chemicals, chloride, or the alkaline present in concrete.

Fiberglass rebar also has a stronger tensile strength than other forms of rebar. It has double the tensile strength and is only a quarter of the weight of steel rebar.

Fiberglass Rebar Environmentally Friendly Factors

Not only does fiberglass rebar provide long-lasting solutions it is an environmentally friendly product for building sustainable concrete structures. The Environmental Protection Agency defines sustainable manufacturing as “the creation of manufactured products through economically-sound processes that minimize negative environmental impact while conserving energy and natural resources.”

TUF-BAR Fiberglass Rebar is an environment-friendly product that aids in the achievement of several LEED® credits in both Canada and the United States. It is the most effective solution for building sustainable concrete structures. As global changes cause more severe weather, having a sustainable concrete solution that is corrosion resistant and requires less rehabilitation of the structure is imperative.

TUF-BAR is proud to be part of the Canada Green Building Network

The Canadian Green Building Network is a national organization that has been working since 2002 to advance green building and sustainable community development practices in Canada. The CaGBC advocates for green building policies with all levels of government and the private sector across Canada. TUF-BAR adheres to these policies in both their manufacturing and their building processes of fiberglass rebar and all composite products.

Glass Fiber Reinforced Polymer (GFRP) reinforcement bar is the solution to corrosion of reinforced concrete structure. Fiberglass Rebar is an excellent replacement for conventional types of steel rebar. Almost all types of steel rebar will eventually corrode and therefore require a type of coating such as zinc. Fiberglass rebar eliminates the possibility of corrosion in the structure and resists a broad range of pollutants experienced in urban environments.

TUF-BAR is seen as both a sustainable and environmental leader in the fiberglass industry in North America. There are many case studies that show the successful applications of our GFRP products. You can purchase fiberglass rebar in a variety of shapes and grades: bent bars, straight bars, columns, piling cages, spiral, rectangular, etc. Custom bars can be manufactured to meet your unique requirements.

The Best Concrete Reinforcement Solution for Marine Structures

Marine structures, such as seawalls, submarine tunnels, piers, and groins, are engineering facilities which are constructed as a source of development and marine resource exploitation. Rock, sand, concrete, and steel are some of the conventional materials used in marine applications. Marine concrete structures have to withstand the extreme environmental pressure. They are subject to corrosive agents which can corrode the reinforcing steel causing spalling, rusting, and shortening the service life of the structure.

Corrosion and marine environment

Corrosion can simply be described as the deterioration of a metal by an electrochemical reaction. The pH of the concrete can fall when it became carbonated, causing the loss of passivity. The passivation layer is broken when chlorides reach the steel. Some of the common causes of corrosion are:

  • Chloride-containing admixtures
  • Sea water
  • Airborne chlorides
  • Carbon dioxide in the atmosphere
  • Sea dredged aggregates

Corrosion process forms rust, causing a seven times increase in the volume of reinforcement bars. The dramatic change in volume causes spalling of the concrete surface making it even more vulnerable to aggressive environment. The abundance of moisture and chlorides make the environment extremely harsh for marine construction projects. Some of the structure that are build in or close proximity to oceans are:

  • Retaining walls, seawalls
  • Floating structures
  • Decks, quays, and piles
  • Boat ramps, jetties, and bulkheads
  • Roads, buildings, and aquariums

How to control corrosion

So far as marine structures are concerned, reinforcement concrete needs to be a highly durable and corrosion-free structural material demanding little or no maintenance. Without correct mixing, design, placement, and curing, the durability of concrete can be impaired. Good practices and quality material can play a role in minimizing the direct maintenance cost and increasing the life cycle of a sensitive concrete structure.

GFRP reinforcement

Glass fiber reinforced polymer (GFRP) reinforcement has compelling mechanical and physical properties that make GFRP particularly attractive for marine structures operating in aggressive environments such as coastal regions, public infrastructure, and buildings that host sensitive equipment. The property of being corrosion-free makes fiberglass rebar a perfect alternative to conventional steel bars which cannot resist rust. Pultrusion is the manufacturing process used to produce fiber reinforced polymer (FRP) bars.

Marine structures reinforced with fiberglass rebar are invulnerable to strong chlorides and moisture. When bonded in concrete, GFRP or fiberglass bars do not react to chemical products, salt, and alkali. Fiberglass rebar is not manufactured with steel or any other metal the pultrusion process helps produce fiberglass rebar that is twice the tensile strength of steel bars. Furthermore, GFRP bars do not interfere with the sensitive electronic equipment.
