Key Features of Sand Bags
– Durable material: Typically woven polypropylene (PP) or burlap, resistant to tearing and bursting.
– Water resistance: Prevents sand loss and maintains barrier effectiveness.
– UV stabilization: Protects against sunlight exposure for outdoor use.
– Easy deployment: Lightweight when empty, quick to fill, stack, and transport.
– Custom sizes: Common dimensions include 30×60 cm, 40×70 cm, and 50×80 cm.
