Polyethylene is the most cost effective and commonly utilized-- it's dense, naturally water-resistant, and durable enough for most camping conditions. Nylon and polyester ground sheets tend to be lighter and much more packable, making them preferred for backpacking.
Hydrostatic Head Ranking
You'll commonly see ground sheets ranked by their hydrostatic head (HH) worth, determined in millimetres. This figure informs you just how much water stress the textile can withstand before it begins to leakage. A rating of 3,000 mm is normally considered sufficient for most camping situations, while anything over 5,000 mm provides strong security in damp or prolonged-rain problems. For ground sheets especially, a greater score is always more suitable, because they're in straight contact with saturated dirt.
Kinds Of Waterproof Ground Sheets
Not all ground sheets are produced equivalent, and the ideal kind depends completely on how you utilize it.
Impact Ground Sheets

Weight and Packability
For base outdoor camping, weight is less of a worry, so durability must take top priority. For backpacking, search for sheets that roll or fold up down tiny and weigh under 300g.
Toughness and Thickness
Determined in denier (D) for woven textiles or GSM (grams per square metre) for non-woven products, thickness directly influences how well the sheet withstands slits. A higher denier or GSM implies better toughness, though likewise even more weight.
Taking care of Your Ground Sheet
To get the most from a water resistant ground sheet, get rid of loose dirt after each usage and clean it down with a damp cloth. Prevent folding it when damp for extensive periods, as this can break down coverings gradually. Shop it freely rolled in a dry location, and occasionally reapply a DWR (sturdy water repellent) spray if the surface starts to wet out instead of grain.
