Quick Answer
To create a ground barrier under your tarp, use rocks, logs, or even an old tire to elevate the tarp's edges, and lay down a bed of leaves, grass, or pine needles to absorb moisture and provide insulation.
Choosing the Right Materials
When selecting materials for your ground barrier, consider what’s readily available in your environment. Pine needles, leaves, and grass are excellent choices as they provide insulation and absorb moisture. If you’re near a body of water, use rocks or logs to elevate the tarp’s edges, creating a dry space beneath. For example, lay down two large rocks on either side of your tarp, angled inward to direct water away from your shelter. This will ensure your ground barrier remains dry and secure.
Creating a Bed of Insulation
Once you’ve chosen your materials, it’s time to create a bed of insulation. Start by laying down a layer of large leaves or branches, followed by a layer of smaller leaves and grass. This will help absorb any moisture that seeps through the tarp and provide additional insulation against the cold ground. For maximum effectiveness, aim for a layer depth of at least 2-3 inches. You can also use pine needles, which can be layered to a depth of up to 6 inches for added insulation.
Securing the Tarp’s Edges
To secure the tarp’s edges, use rocks, logs, or even an old tire to weigh them down. This will prevent the tarp from flapping in the wind and ensure your ground barrier remains in place. For added stability, you can also tie the tarp’s edges to nearby trees or poles using cordage or twine. By securing the tarp’s edges, you’ll create a dry and comfortable space beneath, perfect for a restful night’s sleep.
