Quick Answer
Yes, use rocks for ground insulation under your debris hut to keep your shelter dry and warm, but choose the right size and arrange them correctly to maintain drainage and prevent water accumulation.
Choosing the Right Size of Rocks
When selecting rocks for ground insulation, prioritize those that are 2-4 inches in diameter. These smaller rocks will allow for better drainage and prevent water from accumulating, reducing the risk of water seeping into your debris hut. Larger rocks can be used for the perimeter of your hut to create a solid foundation.
Arranging Rocks for Insulation
Arrange the smaller rocks in a single layer, overlapping them slightly to create a solid bed of insulation. This will help to prevent cold air from seeping into the ground beneath your debris hut and keep the space warm and dry. Make sure to leave space in between the rocks for good drainage and to prevent water from pooling.
Maintaining Rock Insulation
To maintain the effectiveness of your rock insulation, check the layer of rocks regularly for any signs of water accumulation or erosion. Replace any rocks that are damaged or have shifted out of place to ensure a solid layer of insulation. This will help to keep your debris hut dry and warm throughout the winter months.
