SFRC Manhole Cover Overview

SFRC is the first manhole cover to combine the strength and durability of cast iron with the lightweight properties of glass-fiber reinforced concrete. SFRC manhole covers have a multitude of advantages over their traditional counterparts, thanks to the properties inherent in their steel fiber reinforced concrete. All of these come together to deliver a product that lasts longer and costs less to maintain than traditional concrete or iron covers.

Advantages of using SFRC Manhole covers

Advantages of Using SFRC Manhole lids:

  • Anti-theft and anti-burglary. The manhole covers are made from steel fiber reinforced concrete which makes the covers difficult to be removed without machines. As a result, they do not get stolen.

  • Anti-slip. The surfaces of the manhole covers are smooth, making them safe for pedestrians and vehicles even when wet.

  • Lightweight - Easy to install, remove and transport. Compared to other manhole cover materials like cast iron or ductile iron, our SFRC manhole cover is lighter in weight. This makes installation easier and ensures that injuries sustained during manual handling are reduced significantly or eliminated entirely. Workers can easily remove and transport the heavy lid from one place to another without getting injured or falling ill as a result of the strenuous strain required during removal operations at construction sites

  • Long Life Span - Resistant to Corrosion Our products have a higher compressive strength than other materials usually used for manufacturing sewer lids such as cast iron or Ductile Iron (DI). This means that our products can resist corrosion over time better than other materials hence their long life span

Types of SFRC Manhole Covers

Steel Fiber Reinforced Concrete (SFRC) manholes are the new generation of manhole covers from ACO. Created with a unique combination of steel fibers and concrete, SFRC manholes are stronger, lighter and more durable than traditional cast iron covers. Ranging from 100mm to 300mm in height, you can choose from round, square or rectangular shapes depending on your requirements. Each

SFRC manhole is reinforced with steel bars that run along the length of the cover to increase its load bearing capacity. It also features an anti-theft locking system as standard. The wide variety of sizes and shapes makes these covers ideal for any application. They can be used in pedestrian areas, car parks and high traffic areas where various types of vehicles need access to services below ground level.

SFRC Manhole Life Span

The life span of SFRC manhole lids can be increased with proper maintenance. For example, the proper replacement of the jointing material has a significant influence on the service life of the cover. The correct choice and installation of such materials are essential factors in the overall performance of an SFRC manhole cover. With proper maintenance, this lifespan can be reach up to 100 years or more. It’s far longer than traditional cast iron covers (5 to 10 years).

Where Do the Manhole Covers Need to Be Installed?

Manhole covers are perfect for, but not limited to:

  • Roads

  • Pavements

  • Public areas

  • Driveways

  • Gardens and landscaping areas

  • Playgrounds and play areas

  • Parks (including parks) and recreational grounds

SFRC Manufacture and Testing

The product development, production and quality control processes are all tightly integrated to assure consistent quality in our products. The first step in the process is the design and manufacturing of our products. We manufacture both pre-cast and cast-in-place manhole systems to meet your individual needs.

The next step is the test and inspection phase where we provide proof of high quality performance for all SFRC manhole products. Before shipping, each product is inspected by State Departments of Transportation (DOT) approved personnel to ensure that it meets or exceeds state DOT requirements. All SFRC manhole components are tested for compressive strength at outside accredited testing laboratories before being shipped to you.

Final Thoughts

SFRC manhole covers are in place to prevent injuries from falling into the manhole and can help protect pedestrians from injury or capture vital information that may assist the police with a potential crime scene.
