is formed with a double-layer woven fabric, joined together into a matrix of rectangular compartments, each separated by a narrow perimeter of interwoven fabric and containing interconnecting high-strength revetment cables. Similar to precast block mats, once pumped, the ABM is designed to permit differential settling and block articulation.
Form a mattress of individual blocks in a bonded block pattern. The revetment cables become embedded in the blocks to tie the blocks together and resist tension in all directions. The patented separate cable duct design assures that the revetment cables will be positioned securely in the center of each block. Relief of hydrostatic uplift pressure is provided through the narrow perimeter of interwoven fabric after the grout has hardened. ABM is custom fabricated into multiple mill-width panels, designed to fit the actual site dimensions and topography.

Unveil Innovative Solutions With Articulating Block Mat
System 21
A versatile and eco-friendly approach to pipeline protection, it is designed to provide full mechanical protection for exposed pipelines within the creek bed utilizing ARMORFORM articulating block mat 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 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.
