When surface soil conditions are �4�v <br />n n n 10 " <br />loose, use 8 x 1 x 8 or 12 x 1.5 x 12 " <br />metal pins, 8" - 18" pins with 1.5" diameter washer, or 12 -30" J -Shape pins (bent rebar) having a <br />%" diameter. Drive pins or pins flush with the ground surface. <br />5. Soil Filling: There are two options when installing Enkamat -soil filling or non -soil filling. Soil filling <br />Enkamat accelerates performance because the Enkamat, soil and the new vegetation interact <br />together to resist shear forces when water is flowing though the channel or on top of a slope. If soif <br />filling is utilized spread'/ to 3 / inches of fine soil into the mat to completely fill it. <br />A typical condition where non -soil filling is used would be to collect sediment when water is flowing <br />through the channel from an up- gradient source. <br />6. Seeding: For non -soil fillingapplications, broadcast seed or hydroseed over the installed Enkamat. <br />Make sure hydromulch occurs after seeding to ensure the seed reaches the topsoil. if soil filling, <br />seed after filling is completed. You may also seed before and after soil filling to create a better <br />established root structure and increase vegetation strength. Check with your local seeding <br />consultant to verify appropriate seed and fertilizer mixture. <br />7. Sod Installation: if covering Enkamat with sod, soil filling is required. Place sod in the direction of <br />water flow. Periodically install a row or two perpendicular to the flow to reduce the possibility of <br />water flowing along the seams of the sod. In most cases, you should pin the sod down to prevent <br />movement. <br />For technical assistance please contact your distributor or Colbond, Inc., P.O.
