EnkaMat A20 is a three dimensional polyamide mat with an open structure prefilled with a bitumen-bound mineral filter of stone chippings.
When laid on grass seeded soil slopes which are exposed to water, EnkaMat A20 provides a permanent solution to issues caused by hydraulic stress in areas where natural erosion would otherwise have prevailed. The product allows the area to become fully vegetated with the appearance of a grass channel. EnkaMat A20 offers immediate erosion protection from high water velocities and small wave attack.
Functions
• Water erosion protection
• Resistance to high water velocities
Application areas
• Riverbanks
• Lakes
• Canals

• Channels
• Dykes
• Overflow protection zones
• Culverts
• Other surfaces permanently subjected to water impact
Features and benefits
• A permanent solution
• Reinforces vegetation root systems
• Resists high water velocities
• Ensures no hydrostatic pressure build-up behind the protected slopes
• Faster to install than traditional protection systems
• An integrated and robust erosion solution
• Enables root systems to grow and green shoots to sprout through the mat
• Flexible, easily following the profile of the ground surface
• Ensures a natural aesthetic appearance
• No maintenance necessary
• Firmly locked to the ground by the root system
