Common materials for pond tarps include PVC-coated polyester, PVC (polyvinyl chloride), polyethylene, and generic plastic films.
Listings show a range of thicknesses such as 20 mil, 14 mil, and thinner products described as 5 mil. Note that some descriptions inconsistently use ‘5 mm’ or ‘5 mil’ — verify the unit on the product spec to be sure.
Product descriptions vary: some tarps are advertised as fully waterproof (including claims like “100% waterproof”), while others are labeled water‑resistant. Check the individual product listing and specifications to confirm whether a given tarp will fully block rain.
Many tarps list rust‑resistant grommets (brass or aluminum), reinforced edges or corner plates, and rope‑ or hem‑reinforcements to resist tearing at stress points.
Seams and hems are commonly heat‑sealed or made double‑thick and are often rope‑ or hem‑reinforced to limit moisture ingress and add edge strength.
Options include clear/transparent vinyl for visibility and light transmission, dark gray reversible tarps, and blue/silver reversible polyethylene finishes, depending on the listing.
