The Evergreen wall can be used as a retaining wall for earth or rock surfaces, slope stabilizers, or noise barriers. It is ideal for parks, gardens, residential and commercial districts, and along highways and railroads. GRAVITY TYPE RETAINING WALL Capable of withstanding traffic loads and earth pressures. Can vary in height from 3 to 70 feet. ROCK REVETMENT Minimizes the hazard of fractured rock falling onto roadway. Can also be used to cover existing concrete walls or buildings. FREESTANDING NOISE BARRIER Unlike some noise barrier systems, which reflect noise, Evergreen walls fully absorb noise from highways, railroads, or industries. BY PERMATILE NOISE REDUCTION: The excellent sound absorbency of the Evergreen Wall continues to improve as vegetation becomes more established. COST EFFECTIVE: The unique Evergreen component system keeps manufacturing and erection cost down by efficient use of people, time, materials and equipment. An average of 40 sq. ft. of wall surface per element allows for quick assembly. ELIMINATE FALLING ROCK: When bolted directly to a ledge, the hazard of rock falling onto the roadway is minimized. REDUCE GRAFFITI: Limited surface area, which quickly becomes covered with vegetation, drastically diminishes the problem of offensive road art.
