Articulated Concrete Blocks and Mats
Rigid, flexible, and aesthetically pleasing for functional hard armor erosion control.
Whether looking for rigidity, flexibility, or both, Articulated Concrete Blocks, also known as ACBs, are a premium solution for erosion control. Unlike riprap, poured-in-place concrete, and other heavy-duty erosion protection systems, ACBs are both aesthetically pleasing and functional. What’s more, they are easy to install. In comparison to other systems, life-cycle costs are less due to its permanent nature and low-maintenance requirements.
How do articulated concrete blocks provide erosion control?
To explain, ACBs are a flexible, interlocking matrix of uniform size, shape, and weight. Furthermore, they can be hand-placed or connected by a series of cables that pass longitudinally through pre-formed ducts in each block to create a mat. Once the system is installed, ACBs shift with the ground instead of cracking–whereas a concrete slab generally breaks. In addition, ACBs are more porous and flexible, encourage vegetation, and enhance habitat. As a self-weighted system, ACBs have the high tractive force resistance to produce a rigid hard armor lining for erosion control and score protection applications.
What are the key features and benefits of ACBs over other hard armor solutions?
- They are more durable and affordable.
- Resisting both lateral displacement and vertical uplift, ACBs provide more stability.
- They quickly become part of the landscape as well as the environment.

What are Articulated Concrete Blocks?
A versatile solution for erosion control, ACBs safeguard vulnerable areas such as riverbanks, shorelines, or slopes. This is accomplished by forming a flexible, mat-like cover. Professionals hand-placed or interconnect ACBs using cables or geogrids. As a result, this enhances their adaptability and ease of installation. The key to their effectiveness lies in their interconnected nature, which allows the system to flex and conform to changes in the underlying terrain. Consequently, ensuring structural integrity even in the face of soil movement or settling. This feature is particularly crucial in environments subjected to high-velocity water flow or wave action forces. In such scenarios, ACBs excel by dissipating energy and preventing soil erosion. That is why they are an indispensable tool in the battle against erosion.
What are the benefits of Articulated Concrete Blocks?
ACBs are engineered to endure severe conditions, such as high-velocity water flow and direct impacts from waves. As a result, they are an optimal solution across diverse environments. Among their notable attributes are their high strength and durability. In addition, they offer the flexibility needed to conform to changes in the terrain. Furthermore, ACBs are environmentally friendly, support the potential for vegetation, and offer straightforward installation and maintenance. Because maintenance and repairs are minimal, they are a cost-effective and long-term hard armor solution.
