GroundMaster 18oz Tan Canvas Tarpaulins are some of the toughest multipurpose covers available. At 18oz (around 610gsm) these tarps are considered super heavy duty, they have increased resistance to tearing and abrasion, and offer a great deal of protection. These tarps are commonly used in the agricultural and construction industries, protecting machinery, securing truck loads and transporting materials. Due to their robust and breathable nature they have a wide range of additional uses; such as a building tarp, kennel/hutch cover, or as part of a shelter. Fixed eyelets every 2ft allows you to easily secure these covers using bungee cords, ropes and pins. These canvas tarps are rot-proofed and have gained water resistant properties due to being wax-treated.
