UNDERLAYMENT for hay stacks is designed to be used where separation of the hay from the ground moisture and contaminants is necessary to keep the hay stack in premium condition for sale or use at a later date. The Underlayment material is a heavy duty waterproof fabric that can be staked down on the ground and then stacked on. Hay growers utilize a underlayment that is about six feet wider than the hay stack. This allows the fabric to tuck up on both sides about three feet.
Custom sizes also available.
