Nylon and polyester ground sheets have a tendency to be lighter and extra packable, making them prominent for backpacking.
Hydrostatic Head Score
You'll frequently see ground sheets ranked by their hydrostatic head (HH) value, measured in millimetres. This figure informs you just how much water pressure the textile can withstand before it starts to leakage. A rating of 3,000 mm is normally considered enough for most camping circumstances, while anything over 5,000 mm offers strong security in wet or prolonged-rain problems. For ground sheets particularly, a greater score is always more effective, because they're in straight contact with saturated dirt.
Types of Waterproof Ground Sheets

Toughness and Density
Gauged in denier (D) for woven materials or GSM (grams per square metre) for non-woven materials, thickness straight influences exactly how well the sheet withstands slits. A greater denier or GSM means better durability, though additionally more weight.
Caring for Your Ground Sheet
