Are there materials to avoid in moisture-sensitive subterranean homes?

Materials to Avoid

When designing or building a subterranean home, it’s essential to select materials that can withstand moisture and humidity. Avoid using wood, especially untreated or pressure-treated wood, as it can rot and decay in damp environments. Additionally, materials with high cellulose content, such as MDF, plywood, and oriented strand board (OSB), are also prone to damage from moisture. Similarly, avoid using materials with poor insulation properties, such as fiberglass batts, which can become waterlogged and lose their insulating value.

Insulation and Waterproofing Strategies

To mitigate moisture damage, focus on using materials with high water resistance and durability. Consider using rigid foam insulation, such as polyisocyanurate (PIR) or polyurethane foam (PUF), which can maintain its insulating properties even when wet. For waterproofing, use materials like liquid-applied membranes, such as epoxy or polyurethane-based products, which can be applied to walls, floors, and ceilings to prevent water infiltration. Ensure that all joints and seams are properly sealed to prevent water entry.

Best Materials for Subterranean Construction

Opt for materials that are naturally resistant to moisture and humidity, such as concrete, steel, and glass. Consider using low-carbon materials like reclaimed wood or sustainably sourced lumber, which can be treated to resist moisture damage. For flooring, use materials like ceramic or porcelain tile, which are waterproof and easy to clean. When selecting materials, prioritize durability, water resistance, and ease of maintenance to ensure a safe and comfortable living space in your subterranean home.
