Alternate Daily Cover Tarps

With the stiff requirements for standards of operation of a sanitary landfill, and with the expensive, time consuming risky job of obtaining a solid waste permit for a sanitary landfill, the value of a cubic yard of permitted landfill airspace has seen a dramatic increase in value. Since it is becoming increasingly difficult to acquire new landfill space, the cost of providing daily cover has become an important issue. The airspace lost by soil daily cover costs in two ways: 1) the cost of material and application and 2) again for the volume of permitted air space occupied by that daily cover.

We at Airspace Saver Daily Cover have devised a proven system that will maximize your savings in landfill life as well as maximizing the use you get out of your alternate daily cover. Through ten years of having our system out in the field, we have found that our A.S.D.C. has been lasting between twelve months to two years depending on the application techniques and working face condition. The material used is a high density woven polyethylene coated fabric manufactured by Fabrene, Inc. that is heat welded together to the desired width. A series of high tensile strength (6000 lb.) polyester web straps are then sewn on top of the heat welds as well as around the perimeter of the A.S.D.C. for added strength. Steel D-rings are then sewn onto the ends of the straps approximately two feet from the edge.

To help weigh down the tarp in high wind areas, we are able to sew in cable or chain around the perimeter of the cover. This aids in keeping the tarp on the ground while deploying it as well as while it is in place.

Application and removal of the ASDC is easy by attaching the D-rings to available equipment on site and maneuvering the cover. We recommend to position the strap side of the cover down on the working face. When moving the cover, it is best to raise the leading edge as high as possible. In fact, some facilities use a spreader bar system attached to an excavator bucket to completely lift the cover into place. Reducing the amount of drag as much as possible will allow the ASDC to work longer for you.
