NOTES
1. CONDITION OF USE
1.1. FOR PERMANENT STABILIZATION OF SLOPES 2H:1V OR GREATER AND WITH MORE THAN 10 FEET OF VERTICAL RELIEF.
1.2. IN CONJUNCTION WITH SEED FOR FINAL STABILIZATION OF A SLOPE, NOT FOR TEMPORARY COVER. HOWEVER, THEY MAY BE USED FOR
TEMPORARY APPLICATIONS AS LONG AS THE PRODUCT IS NOT DAMAGED BY REPEATED HANDLING.
2. DESIGN AND INSTALLATION SPECIFICATIONS
2.1. INSTALLATION IS CRITICAL TO THE EFFECTIVENESS IF THIS PRODUCT IF GOOF GROUND CONTACT IS NOT ACHIEVED, RUNOFF CAN
CONCENTRATE UNDER THE PRODUCT, RESULTING IN SIGNIFICANT EROSION..
2.2. JUTE MATTING MUST BE USED IN CONJUNCTION WITH MULCH. EXCELSIOR, WOVEN STRAW, BLANKETS, AND COIR ( COCONUT FIBER) BLANKETS
MAY BE INSTALLED WITHOUT MULCH.
2.3. PURELY SYNTHETIC BLANKETS ARE ALLOWED, BUT SHALL ONLY BE USED FOR LONG-TERM STABILIZATION OF WATERWAYS. THE ORGANIC
BLANKETS, ARE BETTER FOR SLOPE PROTECTION AND SHORT-TERM WATERWAY PROTECTION BECAUSE THEY RETAIN AND PROVIDE ORGANIC
MATTER TO THE SOIL, SUBSTANTIALLY IMPROVING THE SPEED AND SUCCESS OF RE -VEGETATION.
3. MAINTENANCE STANDARDS
3.1. GOOD CONTACT WITH THE GROUND MOST BE MAINTAINED, AND THERE MOST NOT BE EROSION BENEATH THE BET OR BLANKET.
3.2. AREAS OF THE NET OR BLANKET THAT ARE DAMAGED OR NOT CLOSE CONTACT WITH THE GROUND SHALL BE REPAIRED AND STAPLED.
3.3. IF EROSION OCCURS DUE TO POORLY CONTROLLED DRAINAGE, THE PROBLEM SHALL BE FIXED AND THE ERODED AREA PROTECTED.
