Propex Launches New Engineered Mattress System for Scour and Erosion Protection
Propex is starting 2022 with the launch of PYRAMATTRESS® Engineered Mattress System, an erosion control solution designed to resist potential scour and erosion caused by the constant flow of water or high hydraulic stresses.
The system utilizes the durability and erosion resistance of PYRAMAT® 75 High-Performance Turf Reinforcement Mat (HPTRM) to construct a geosynthetic, soil, and rock composite for protection of channels, slopes, and spillways.
The design of this system allows for smaller rock-fill size, which improves water flow over traditional solutions. Smaller void space also allows for reduced erosion and higher performance overall.
The patented system offers a low carbon alternative to conventional hard armoring solutions, such as reno mattresses, rock riprap, and concrete mats. Unlike these technologies, PYRAMATTRESS components are corrosion resistant and promote vegetation, allowing for an increased design life that is environmentally friendly.
PYRAMATTRESS was used to protect a drainage channel used to convey surface runoff from a luxury housing development to detention storage bins.
