Quick Answer
A $50 tarp can provide adequate moisture protection in a survival situation, but it depends on several factors, including the quality of the tarp, the installation method, and the severity of the weather conditions.
Tarp Selection and Quality
When selecting a tarp for moisture protection, look for one made from a waterproof and breathable material such as nylon or polyester. A 6-10 mil thickness is suitable for most survival situations. The ideal size is 9x12 feet or larger to provide adequate coverage. Some popular options include the Silnylon 9x9 tarp or the Tyvek 9x12 tarp.
Installation Techniques
To maximize the effectiveness of a tarp as a moisture barrier, use a ridgepole installation method. This involves creating a central pole to support the tarp, and then anchoring the tarp to the ground using stakes and rope. This design allows water to run off the tarp and prevents it from pooling under the fabric. The ideal angle for the tarp is between 30-45 degrees to ensure water runs off and doesn’t accumulate.
Additional Considerations
When using a tarp as a moisture barrier, it’s essential to consider the wind direction and precipitation intensity. If winds are strong or precipitation is heavy, consider using additional anchoring points or a reinforced tarp to prevent damage. Additionally, use a tarp shelter in combination with other moisture protection methods such as a bivy sack or a ground tarp to maximize overall protection.
