Foam Concepts LLC pioneered the original portable hand-mix PUF, designing, packaging, and selling two-part, self-contained rigid pour foam systems for a wide range of geotechnical applications. Our aim is to help you tackle closure and filling challenges using advanced, proprietary chemical systems and packaging.

Federal and state agencies, general contractors, and conservation groups across all 50 U.S. states, 10 Canadian provinces, and more than 12 countries rely on Foam Concepts LLC products. Whether your project involves mine closures, landfill gas wells, blast holes, or exploration holes, our solutions and expertise can help you work faster, more efficiently, and in an environmentally conscious way.

Our products are certified NSF/ANSI/CAN 61 for potable water applications and comply with USCG Title 33, Chapter 1, Part 183 as flotation foam. The packaging ensures structural fill materials reach remote locations quickly, simply, and with minimal environmental impact. Installing our products requires no special equipment and only basic training or experience.

We've been showcased on the Discovery Channel's Dirty Jobs and the Smithsonian Channel’s “How did they fix that?” (Season 3: Episode 6). If you can fill it with concrete, grout, or dirt, foam can do it too—faster, cheaper, and more easily!
