<p>A 'flexible mat' for lining embankments, comprises a body or upper and lower surfaces having an interior with a plurality of chambers (II), a plurality of fracture zones (gaps 32) and plurality of different zones, filter zones (12, 13). The filter zones (12, 13) are woven and porous allowing water to pass through the mat. The chambers (II) and fracture zones (32) are arranged to be filled with a setting substance, e.g. concrete. Once hardened or if the mat is moved, the fracture zones (32) fracture, but the mat remains intact and in one piece.</p> |
