Mineshaft Closures Boise, Idaho
The once-booming mining industry left thousands of abandoned mineshafts scattered across the U.S.—many of them hidden beneath growing residential and recreational areas. These sites pose serious safety risks, including cave-ins, toxic gases, and dangerous wildlife. Remote locations, unstable ground, and large mine shaft openings often make traditional filling methods costly and impractical. To restore safety and stability, we provide strategic solutions by sealing mineshafts with geotechnical spray foam and geotextile fabrics.
How We Can Help
With the increased dangers that old mine shafts pose, our geotechnical foams are an excellent, cost-effective solution to closing and abandoning old mine shafts. Our foams are environmentally friendly, water-blown, and highly resistant to acid-rock drainage.
Fast-Expanding Foam for Complete Sealing
Within seconds to minutes of mixing our two-part liquid foams, they expand rapidly (usually 30 to 40:1) to fill voids and cracks in the mine shaft opening. The foam quickly hardens, forming an extremely rigid plug that firmly bonds to the surrounding rock of the mine shaft. This creates a strong, shrink-resistant, and secure mine shaft closure that also helps protect against groundwater contamination.
Efficient Closure of Large and Vertical Openings
One of the main advantages of our expandable geotechnical foams is their ability to close large mine openings quickly while using a fraction of the material required by dirt, rock, or concrete.
When sealing vertical mine shafts, we use geotextile fabric to cover the opening. Once in place, we spray the liquid foam from a safe distance, allowing it to expand and form a lightweight but incredibly strong foam plug. After curing, the area can be backfilled with native soil, creating an environmentally safe mine shaft closure.
Ideal for Remote Access Locations
Accessing remote sites can be a challenge when it comes to mineshaft closures. Fortunately, our foam systems can be transported easily in manageable quantities using 4-wheel UTVs, ATVs, horseback, bush planes, or helicopters — no heavy equipment required.

FAQs
-
What is a mine shaft closure and why is it necessary?
Mine shaft closure is the process of permanently sealing abandoned mine openings to eliminate safety hazards such as cave-ins, toxic gas exposure, and wildlife intrusion. Closures help protect people, animals, and the environment from long-term risks.
-
How does Go Green Insulation seal abandoned mine shafts?
We use a two-part geotechnical spray foam that expands rapidly to fill voids and hardens into a rigid, shrink-resistant plug. For vertical shafts, we apply geotextile fabric before spraying foam from a safe distance, then backfill the area with native soil.
-
Is your foam environmentally safe for mine shaft closures?
Yes. Our foam is water-blown, environmentally friendly, and resistant to acid-rock drainage—making it a safe solution for sealing mine shafts without contaminating the surrounding ground or groundwater.
-
Can your system be used in remote locations?
Absolutely. Our foam materials are lightweight and easy to transport using ATVs, UTVs, horseback, bush planes, or helicopters—making them ideal for difficult-to-access mine sites.
-
Why use foam instead of traditional fill materials like dirt or concrete?
Foam expands rapidly, bonds tightly to rock, and requires far less material than dirt or concrete. It’s a faster, more cost-effective, and more practical solution—especially for large or vertical shaft closures.
