Enviroflex: Articulating Concrete Block (ACB)

Enviroflex®: Bridging High-Performance Engineering with Living Ecosystems

Enviroflex® is an advanced articulating concrete block system designed to transform traditional erosion control into a regenerative landscape. While engineered for high-velocity riverine and channel flows, its primary distinction lies in its ability to foster natural habitats and maximize groundwater infiltration.

Key Ecological Advantages:

Hydrologic Restoration

Unlike solid concrete or asphalt linings, Enviroflex® features integrated openings that facilitate direct groundwater recharge. This reduces peak runoff, mitigates downstream flooding, and filters out stormwater pollutants before they reach the water table.

Riparian Habitat Creation

The system is designed to capture sediment infill during storm events, providing a fertile foundation for the establishment of native riparian plants. This creates a cyclical, self-sustaining natural habitat that supports local biodiversity.

Natural Biofiltration

By allowing vegetation to take root within the armor layer, the system promotes biofiltration, improving water quality while replacing the industrial look of “hard armor” with a lush, green aesthetic.

Stable, Living Shorelines

The vertically interlocking, fiber-reinforced blocks provide a permanent, scour-proof bottom that doesn’t sacrifice the environment for stability. It offers a superior, eco-friendly alternative to rip-rap and gabion mattresses, which often disrupt local flora and fauna.

Eco-Engineered Competitive Advantages:

While many systems rely on heavy machinery or invasive hardware, the Enviroflex® Concrete Block (ACB) System provides a high-performance, low-impact solution through superior design:

Integrated Vertical Interlock

The unique overlapping connection creates a unified armor layer that prevents individual blocks from shifting or protruding. This 0″ protrusion profile ensures a smooth hydraulic surface, protecting the growing habitat from turbulent scour.

Advanced Material Strength

Manufactured from fiber-reinforced concrete, Enviroflex® offers enhanced tensile strength and durability without the bulk of traditional concrete, allowing for a thinner, more “breathable” footprint.

Cable-Free Flexibility

Unlike traditional ACBs that require integrated cables, Enviroflex® requires no cables. This allows the blocks to settle naturally and conform to the irregular contours of a riverbed or channel, ensuring better soil contact and more effective infiltration.

Low-Impact Installation

The system is designed for easy installation without the need for heavy cranes. This significantly reduces site compaction and preserves the integrity of the surrounding natural environment during the construction phase.

Minimized Environmental Footprint

The thin profile of Enviroflex® requires significantly less excavation, trucking, and site disturbance than traditional systems. This represents a fundamental shift from merely “containing” nature to actively participating in its long-term health and ecological recovery.

Enviroflex® – Articulating Concrete Block (ACB) – Installation Steps

Step 1 Prepare the Area The subgrade is prepared per the project requirements. Cut-off walls are installed as specified by the engineer.

Step 2 Install the Filter Fabric Install the appropriate filter fabric as specified on the drawings. If a drainage layer is required, it may be placed concurrently to keep the fabric in place.

Step 3 Place the Block Blocks are either hand-placed or placed with a grappling attachment on an excavator. Please contact us for rental information.

Step 4 Closure Pours On terminal ends and areas where Enviroflex® abuts existing structures, concrete is typically poured to finish the area. The concrete should be reinforced, have the same strength as the block, and typically be at least 6 inches wide.

Step 5 Infill The open cells of Enviroflex® are either backfilled with suitable soil for vegetation, with 3/4 inch diameter crushed stone, or left bare.
