Equipment-less Foam Sealant™ or EFS™ works by expanding in a mine void to fill and adhere to the perimeter. Starting as a liquid, once mixed, the foam turns to a gel which can be poured into a hole, crack or void. The long gel time allows EFS™ to flow outwards, making good contact with the rock. Once it begins to rise, EFS™ both adheres to and interlocks with the surrounding rock.
New user tips and Installation instructions will give you more information on how to open, mix and pour EFS™. Be sure and watch the videos too.
EFS™ will work at any temperature above freezing. It does work best, however, under certain conditions. Review the recommendations for extreme installation conditions for tips on very hot, very cold and wet conditions.
Manufacturer recommendations for extreme weather installation
How strong is EFS™? Well, it has held up to 64,000 pounds! That works out to almost 5 psi on the wetted perimeter and very near the ultimate compressive strength. Also, due to the cohesion and friction with the surrounding rock, a foam shaft plug will retain two-thirds of its capacity AFTER failure!
