Quick Answer
Short Answer: Yes, using a ground cloth under your tarp shelter is a good idea as it helps to protect the underside of the tarp from abrasion, punctures, and water pooling that could compromise the integrity of your shelter.
Choosing the Right Ground Cloth
When selecting a ground cloth, look for materials that are waterproof, breathable, and durable. A good option is a silnylon or nylon tarp material with a thickness of at least 0.8 mm. A larger ground cloth is also more beneficial as it provides better coverage and protection against water and abrasion.
Setting Up the Ground Cloth
To set up the ground cloth, stake it down with rocks or sticks on all four corners to create a taut surface. Make sure to leave a small gap between the ground cloth and the tarp to allow for airflow and moisture transfer. If using a frame tarp, attach the ground cloth to the tarp’s perimeter using cordage or clips to prevent it from shifting during wind and rain.
