ENVIROFLEX® is an interlocking articulating concrete block (ACB) revetment system designed for erosion control use in riverine and channel environments or other areas with high velocity fl ows subject to scour.

Manufactured from fi ber reinforced concrete, each block interlocks with overlapped edges, eliminating the block’s ability to overturn under fl ow conditions. ENVIROFLEX® is free from protruding edges so cabling or other connection devices are not required for hydraulic stability. Openings in the block units enable vegetation to establish, providing a green, natural, and environmentally pleasing appearance while allowing stormwater infi ltration and promoting groundwater recharge. ENVIROFLEX® is FHWA tested.

Cost effective and environmentally friendly.

The ENVIROFLEX® interlocking ACB system offers a cost effective and environmentally friendly

alternative to rip-rap, gabion mattresses, concrete or asphalt linings and other hard armor

systems. By requiring a thinner section, less trucking and lower maintenance costs, this unique

system provides ample opportunity for signifi cant savings over standard project costs. The

products ability to accept sediment infi ll from storm events allows the establishment of riparian

plants and enables cyclical natural habitat while providing a stable and scour proof bottom.

ENVIROFLEX® is an economical, durable, and environmentally sound soil

stabilization system. The palletized product can be delivered right to the

installation site and is easily placed with small track equipment in locations

where cranes would fi nd it diffi cult to reach. Using a specialized grappling

tool allows placement of four pieces at a time for rapid installation.
