Polyethylene is one of the most budget-friendly and commonly utilized-- it's thick, naturally waterproof, and resilient sufficient for the majority of camping problems. Nylon and polyester ground sheets have a tendency to be lighter and a lot more packable, making them prominent for backpacking.
Hydrostatic Head Score
You'll often see ground sheets rated by their hydrostatic head (HH) value, determined in millimetres. This number informs you just how much water stress the fabric can endure prior to it begins to leak. A rating of 3,000 mm is generally thought about sufficient for most camping scenarios, while anything over 5,000 mm offers solid defense in damp or prolonged-rain problems. For ground sheets canopy tent especially, a higher rating is constantly better, since they're in straight contact with saturated dirt.
Kinds Of Waterproof Ground Sheets

Weight and Packability
For base camping, weight is less of a problem, so resilience should take concern. For backpacking, look for sheets that roll or fold up down small and consider under 300g.
Resilience and Density
Measured in denier (D) for woven materials or GSM (grams per square metre) for non-woven products, thickness straight influences just how well the sheet withstands leaks. A greater denier or GSM implies greater toughness, though additionally even more weight.
Caring for Your Ground Sheet
To get one of the most from a water resistant ground sheet, shake off loose dirt after each usage and clean it down with a damp cloth.
