Concrete mattresses are Grout-filled mattresses (mats) that are comprised of a two high-strength polyamide and/or polyethylene woven layers connected together by interweaving or the use of spacers.

Concrete mattresses are either permeable, flexible or rigid with a non-uniform thickness, or impermeable, rigid and with a constant thickness.

ADVANTAGES :

• They are used for erosion protection as they have a high resistance to hydraulic loads and they readily adapt to the ground profile and have a high UV and abrasion resistance giving them a long service life.

APPLICATIONS:

Typical applications include Erosion protection of river, canal, and dykes banks and groins against wave attack and flowing water. Sealing of watercourses, canals and lagoons Erosion protection in the intertidal zone, Protection of inshore / offshore pipelines and structures or to replace the conventional riprap system and protection of pipes .
