EROSION STOP - FOLD OF <br />MATTING BURIED IN SLIT <br />TRENCH AND TAMPED DOUBLE ROW <br />OF STAPLES. <br />NOTES: <br />1.APPLY LIME, FERTILIZER AND SEED BEFORE LAYING THE NET OR MAT. <br />2.START LAYING THE NET FROM THE TOP OF THE CHANNEL OR SLOPE AND UNROLL IT DOWN THE GRADE. ALLOW NETTING TO LAY LOOSELY ON THE SOIL <br />BUT WITHOUT WRINKLES - DO NOT STRETCH. MAT OR BLANKET - TYPE PRODUCT SHOULD PROVIDE AT LEAST 30% COVERAGE OF THE SURFACE WHERE IT <br />IS APPLIED. <br />3.TO SECURE THE NET, BURY THE UPSLOPE END IN A SLOT OR TRENCH NO LESS THAN 6 INCHES DEEP, COVER WITH SOIL, AND TAMP FIRMLY AS SHOWN. <br />STAPLE THE NET EVERY 12 INCHES ACROSS THE TOP END AND EVERY 3 FOOT AROUND THE EDGES AND BOTTOM. WHERE 2 STRIPS OF NET ARE LAID SIDE <br />BY SIDE, THE ADJACENT EDGES SHOULD BE OVERLAPPED 3 INCHES AND STAPLED TOGETHER. EACH STRIP OF NETTING SHOULD ALSO BE STAPLED DOWN <br />THE CENTER, EVERY 3 FOOT. DO NOT STRETCH THE NET WHEN APPLYING STAPLES. <br />4.TO JOIN TWO STRIPS, CUT A TRENCH AND ANCHOR THE END OF THE NEW NET. OVERLAP THE END OF THE PREVIOUS ROLL 18 INCHES, AS SHOWN, AND <br />STAPLE EVERY 12 INCHES JUST BELOW THE ANCHOR SLOT. <br />MAINTENANCE: <br />INSPECT ALL MULCHES PERIODICALLY, AFTER RAINSTORMS TO CHECK FOR RILL EROSION, DISLOCATION, OR FAILURE. WHEN EROSION IS OBSERVED, APPLY <br />ADDITIONAL MULCH. IF WASHOUT OCCURS, REPAIR THE SLOPE GRADE, RESEED, AND REINSTALL MULCH.
