Agritel Gravel Bags – very useful for holding covers and sheeting in place. A variety of uses. They can be used to hold silage clamp covers in place and can be used as a ballast for Toptex Hay and Straw Covers. Each gravel bag is supplied with a draw tie and needs to be filled with stone/gravel. When filled with pea gravel, they will weigh around 12kg. The bag remains soft, resistant and flexible once filled, helping to create an airtight seal around the silage clamp. Bags will not retain water so don’t freeze, and hold their weight and shape. Please note bags must be filled with gravel/stone and not sand! Much easier to work with than a smelly old tyre! Fillable area: 960mm x 210mm. Large orders may be dispatched on a pallet.
