Erosion control solutions

Rock Bags, Flexible & Sustainable, Erosion Protection. A sustainable environmental civil engineering alternative solution to gabions, large rock, blockstone, free rip rap and rock mattresses.
The Rock Bags reduce water flow velocity as water energy is absorbed into the space between the rocks. When installed under water, the spaces between the rocks provide a habitat for aquatic life.
They can be covered with soil to support plant regeneration to further protect the at risk environment and assist revegetation.

Why You Need Rock Bags for Bridge Scour Prevention

Bridges are a vital component in the transportation system in any country. They improve accessibility and help you travel and transport goods easily. But, did you know that scour is one of the biggest culprits behind bridge failures? Hence, bridge scour prevention is 100% essential. This is why early detection and action are crucial to prevent damage and safeguard bridges. Rock Bags are a globally recognized solution for bridge scour prevention .

What Is Bridge Erosion?

Bridge scour means soil erosion that occurs around a bridge foundation like pylons and piers. Bridges that run over waterways, as well as dry creeks, are both at risk of erosion. We need to pay attention to bridge erosion control in both these situations. Let us explain why. Bridge pylons and piers are the core supporting structures of bridges, and they are held firmly in place by sand. Bridges that run over rivers, lakes, and creeks are susceptible to water erosion because of continuous water flow. The currents disrupt the surface soil layer, specifically the soil around pylons and piers. This bridge pier scour can destabilize the bridge structure gradually.

How Do Rock Bags Help Bridge Scour Prevention?

Placing Rock Bags around bride pylons and piers can help you manage bridge erosion effectively. During a crisis like floods, they are the quickest and easiest solution to deploy. They prevent soil from being washed away by floods and help in retaining the strength of bridges.
A 2-tonne Rock Bag can withstand velocities up to 4.7m/sec, and a 4-tonne Rock Bag can withstand 5.3m/sec, proving their efficacy in bridge pier scour protection.

Rock Bag uses in the Rail Industry

Rock Filter Bags are renowned globally for their flexibility, efficacy, and sustainable quality. Many different types of constructions such as railways, ports, roads, bridges, and waterways use them. Over the past years, these Rock Bags proved to be very useful for the rail industry when it comes to bridge scour protection and many other issues.

Rail Bridge Scour Protection

Stabilization of River Embankments, Riverbanks, Creek Banks, and Riverbeds In addition to strengthening bridges, it’s also important to ensure the river banks along railways are protected from erosion. Rock Bags have been widely used for water erosion prevention due to the ease of installation. They are a great alternative to concrete foundations along waterways.

Water Erosion Control in Rivers and Waterways

Water erosion can become a severe issue if not identified and controlled in its first stage. As more and more soil particles get washed away, the soil structure becomes unsteady, threatening the wildlife and plants in the area. But that’s not it! Lack of water erosion control can eventually deteriorate the water quality as harmful chemicals from the eroded riverbank get mixed with the waterways.
Moreover, it can become inhospitable for marine life and unsafe for the public.

Why Choose Rock Bags for Water Erosion Control?

There are many water erosion prevention methods, such as gabions, fibre rolls, riprap, and strip cropping. However, most of them are either costly, time-consuming or not environmentally-friendly.

Our 2-tonne Rock Bag offers scour and erosion protection against water velocities up to 4.7m/sec, and a 4-tonne Rock Bag can withstand up to 5.3m/sec. They remain a better option in many ways thanks to;

Offering rapid deployment

Being eco-friendly. The Kyowa Rock Bags support vegetation growth
They feature a single-point lifting system
Get up to 30 years of protection against UV rays. Plus, 50 years of duration in water.
No need for foundation work is required for installation
Extremely flexible and simple to handle

Rock Bags for Road Erosion Control

Nowadays, road erosion control is of the essence. Roads, as the core type of infrastructure of transportation networks, are susceptible to depreciation over time. With increased usage, roadways can sustain damages, the most extreme form being sinkholes. They can disrupt daily travel and transportation, inconveniencing public life.
Here is a list of features of filter units that make them stand out;

Rapid deployment

Single-point lifting system Eco-friendly and supports vegetation growth Durable and long-lasting. You can rely on them for up to 50 years in water and up to 30 years’ protection against UV rays No foundation required for installation Flexible

Building Offshore Barriers & Stopping Subsea Corrosion with Rock Bags

Rock Bags are a popular product for erosion prevention, used in various sites across the globe today. However, this unique product aids us in many other situations as well. Rock bags are eco-friendly, durable, and long-lasting, so they are readily used in offshore and undersea projects for purposes varying from submarine cable protection to offshore barriers construction

Why Is It Important to Build Offshore Barriers and Protect Underwater Structures?

Protecting offshore structures like wind farms, oil platforms, gas production sites, and bridges is a matter of paramount importance. The design and construction of these structures are costly. Hence, it’s vital to sustain them for a long time.

These offshore sites are more prone to heavy winds, seismic forces, strong currents, and other factors associated with the location. In situations of damage or collapse, they can pose a threat to marine life. Therefore, the foundations of offshore barriers and sites should be strong.

It is also important to pay attention to submarine cable and pipeline protection as they usually carry gas and oil.

Damage can cause a leak, releasing these substances to the marine ecosystems, which is very harmful. It can be due to a heavy object dropped on them, an anchor dragging the cables accidentally, or a natural phenomenon like a storm.
Moreover, constant exposure to seawater leads to corrosion.

How Do Rock Bags Help?

A product as simple as Rock Bags can help you protect valuable marine structures. Moreover, by using them, you can,

Build offshore barriers
Tackle coastal erosion
Provide pylon protection for bridges
Protect subsea pipes and cables from subsea corrosion
Stabilize subsea pipes and cables from swaying and moving
Support the foundation of navigation towers, wind turbines, and other offshore structures

What Are The Features of Rock Bags?

Here’s why Rock Bags are the best option for your offshore projects!

A 2-tonne rock bag offers scour and erosion protection against water velocities up to 4.7m/sec. Moreover, a 4-tonne rock bag can withstand up to 5.3m/sec. Rapid and automated deployment. The R.O.V aided release system can drop the bags at the precise location safely. Even though in most cases is not necessary, a diver can assist with the deployment.
They are eco-friendly and support marine life. Rock Bags become an ideal habitat and breeding ground for small fish over time
