Nylon and polyester ground sheets tend to be lighter and extra packable, making them preferred for backpacking.
Hydrostatic Head Score
You'll commonly see ground sheets ranked by their hydrostatic head (HH) value, gauged in millimetres. This figure informs you how much water pressure the material can endure prior to it starts to leak. A score of 3,000 mm is typically thought about sufficient for the majority of camping circumstances, while anything over 5,000 mm provides strong defense in damp or prolonged-rain problems. For ground sheets especially, a greater score is always more suitable, considering that they're in straight contact with saturated soil.
Sorts Of Waterproof Ground Sheets

Weight and Packability
For base camping, weight is much less of a concern, so toughness should take concern. For backpacking, seek sheets that roll or fold down little and weigh under 300g.
Durability and Density
Gauged in denier (D) for woven textiles or GSM (grams per square metre) for non-woven materials, density straight affects exactly how well the sheet stands up to punctures. A higher denier or GSM suggests greater durability, though additionally more weight.
Caring for Your Ground Sheet
To obtain one of the most from a waterproof ground sheet, shake off loosened dust after each use and clean it down with a wet cloth.
