Sealing Solutions to Protect Your Geodesic Dome from Water Intrusion
To ensure your Ekodome® stays dry and weather-tight, it’s essential to create a proper seal around the base of your dome where it meets the foundation. The best sealing method depends on the type of foundation you’re using, whether it’s a concrete pad, wooden deck, or another structure.
Recommended Base Sealing Methods
Here are common sealing solutions that help prevent moisture, rain, and groundwater from seeping into your dome:
-
Exterior-grade caulking: flexible and waterproof, ideal for small gaps or uneven surfaces
-
Silicone sealant: long-lasting and weather-resistant, great for exposed edges
-
Flashing: a metal or waterproof membrane that bridges the gap between the dome and the foundation, providing a protective overlap
Example: Using Flashing with a Custom-Fit Foundation
If your foundation has been designed to perfectly match the contour of the dome, flashing is a great solution. It wraps around the base, extending the dome’s coverage and creating a reliable moisture barrier.
