About Us MineSeal is a women-owned emerging small business. MineSeal, LLC (MineSeal) is a limited liability corporation of professionals with diverse backgrounds from the engineering, construction, mining, geological and environmental professions. MineSeal manufactures, distributes and installs PUF-Seal®, a polyurethane foam (PUF) sealant used to permanently close hazardous mine shafts, adits, abandoned wells and other constructed earth openings. MineSeal has offices in Arizona, Nevada and Idaho and a packaging facility and warehouse in southern Nevada.

MineSeal’s expertise and experience can solve unusual cavity closure problems related to mining and construction operations. Our diverse background allows us to assist consultants, mining companies, construction companies and land developers. We can assist those individuals who must meet both State and Federal regulatory and environmental conditions required by the mine closure process.
