Eco-Flex Articulating Block Mat

They are identical to Ercoform but include open cells to provide environmentally compatible protection against periodic high flows. Eco-Flex mats are comprised of concrete-filled elements and unfilled areas, allowing for the establishment of riparian vegetation.

Woven in such a manner as to provide a woven double-layer, joined into a matrix of rectangular compartments (blocks), each separated by an area of non-woven yarn to produce a 25% open cell mat. Ducts (grout tubes) interconnect each block, and high-strength revetment cables are installed between blocks and through the grout tubes, joining one block to the next. The non-woven areas between the blocks serve as a hinge to permit articulation, while the cables remain embedded in the concrete blocks to facilitate articulation.

A versatile and eco-friendly approach to pipeline protection, it is designed for complete pipeline coverage within the creek bed utilizing Ercoform™ while promoting the growth of local riparian vegetation within the mat along the creek banks, utilizing Eco-Flex™.

Designed for complete pipeline coverage within the creek bed utilizing Ercoform while promoting the growth of local riparian vegetation within the mat along the creek banks incorporating Eco-Flex. This is accomplished by a two-phase mat, where an Ercoform solid mat and an Eco-Flex open-cell mat are combined during manufacturing and inflated on-site.
