Quick Answer
Debris huts can provide adequate shelter in high humidity, but their effectiveness depends on the design and construction of the hut. A well-built debris hut can protect occupants from wind-driven rain and maintain a relatively dry interior.
Designing for High Humidity
When building a debris hut in high humidity environments, it’s essential to emphasize ventilation and slope. A minimum roof slope of 45 degrees and overhangs of at least 2 feet can help to shed rain and reduce the likelihood of water accumulation. Aim for a debris-to-tarp ratio of 60:40 to minimize water absorption.
Construction Techniques
To create a stable and water-resistant debris hut in high humidity, use a mix of 2/3 softwoods (e.g., pine or spruce) and 1/3 hardwoods (e.g., oak or maple). A 1:1 ratio of pine needles to grasses or small branches will provide adequate insulation. For added water resistance, apply a 1/4 inch layer of mud or clay around the structure. This will also help to seal gaps and cracks.
Tips and Considerations
Regularly inspect and maintain your debris hut, paying close attention to the condition of the roof and walls. Consider adding a 6-foot radius of cleared space around the hut to promote air circulation and reduce the risk of water accumulation. If you’re building in an area with heavy rainfall or frequent flooding, consider using a tarp with a waterproof coating or adding a secondary waterproof layer to the hut.
