• <br />high flow channel <br />3-4 pins per sq. yd. <br />low flow channel <br />2-3 pins per sq. yd. <br />Always install two rows of pins <br />spaced 1.5 x 1.5 feet apart at all <br />roll splice locations. <br />4 <br />Anchoring Devices: Typically 11-8 \, <br />gauge of a 6" x 1" x 6" metal pins are r ,i <br />used. When surface soil conditions are ~~v~~~ <br />~~ <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" <br />'/a" diameter. Drive pins or pins flush with the ground surface. <br />CHECK SLOT AT 25' (7.6) lHTERVALS <br />(OR DOUBCE ROW Of PINS) <br />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 soil <br />filling is utilized spread '/z to 3/4 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 filling applications, 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.
