Features:

• Innovative design gives the system the flexibility to adapt to ground movement and grade changes while maintaining stability.
  
• Subgrade preparation time and costs are reduced due to the flexible properties of the mats.
  
• Open areas within the mats permit plant growth which enhances the system's stability over time.
  
• Air-entrained concrete for durability and freeze-thaw fracture resistance.
  
• Royal will supply detailed engineering expertise to aid in the design of your project.
  
• Ideal for a wide range of applications including channel linings, dam/spillway overflow protection, lakeshore protection, slope stabilization and more.
  
• Exceeds both federal and state D.O.T. requirements (as verified by a complete engineering analysis with flume testing).

Cable Concrete™ protects underlying subgrades while allowing beneficial vegetative growth. This mattress system consists of concrete blocks, integral stainless steel cables which are poured into the blocks and pre-attached geotextile fabric. The innovative design gives the system the flexibility to adapt to ground movement and grade changes while maintaining stability.
