Stockpile Covers

Fleximake Stockpile covers are ideal for protecting your valuable stockpile from rain and wind erosion, UV damage, pest and animal ingress, dust contamination and human contact. Our stockpile covers are suitable for both short term and long term storage. Stockpile covers are one of the most efficient and economical methods available for protecting various types of bulk products. They can also prevent manufacturing downtime by keeping your products in perfect quality and condition. Our tarp covers can be used to ensure compliance with environment obligation by preventing contaminated rain water runoff, wind blow dust and odour nuisance. They are tough, durable, tear and abrasion resistant, 100% waterproof and are available in Polyethylene(PE) and Polyvinyl Chloride (PVC) materials. Our tarp cover seams are heat welded using sophisticated welding machines that result in strong bonds and waterproof seams. Unlike stitched seams, the welded seams in our bulk storage covers will not rot, break or leak. We provide a variety of cover securing choices including roped edges, webbing straps, weights, hook & loop fasteners, eyelets and etc.

To suit your product, we can custom make your cover to the required dimensions. If you are struggling to determine the size of the cover, we can assist you with calculating it. To do this, we would generally need to know:
  • Repose angle of product
  • Height limit of the material stacking equipment
  • Required tonnage
  • Specific gravity

  • Stockpile Cover

    We are also capable of manufacturing tarps to suit large, complex shaped stockpile through determining the sizes of sectional tarps by processing contour diagrams.
    In addition to this, we can provide you with groundsheets. A groundsheet may be required for some stockpiles and they will help you to keep your product in perfect condition. We can manufacture almost any size groundsheet to allow you to have the perfect solution. We can also assist you with calculating the best size for your groundsheet.
    We manufacture all our stockpile covers in Australia. We here at Fleximake have the fastest and most sophisticated plastic welding machines in Australia. The modern tech, high speed machines bring us the capability to guarantee you a fast delivery regardless of the size of bunker cover. This also means that we can offer you very competitive prices as opposed to our direct competitors.
