ECO FLEX ARTICULATING BLOCK MAT

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 the riparrian 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 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 growth of local riparian vegetation within the mat along the creek banks incorporating Eco-Flex. This is accomplished by a two-phase mat were an Ercoform solid mat and an Eco-Flex open cell mat are combined during manufacturing and inflated on site.
