Instantly-expanding foam bridge provides barrier for bentonite to prevent solids from entering the screened interval. Allows rapid grouting to save time in the field.

                                   This compressible foam seal, wrapped in a polyethylene sleeve,expands                                    instantly when it exits the bottom of the drive casing, to provide positive                                    placement of a barrier that prevents solids from entering into the screen interval. Provides a positive grout barrier when used above the water table with granular bentonite.

GeoInsight Quick Seal Sleeves are the fastest way to install a low- permeability annular seal below the waterline. Grouting can begin almost immediately.

                                          Threads into the casing string to provide positive placement of a fast,                                           low-permeability annular seal below the water table. 1/2" and 3/4"                                           models fit in most 2" and 2-1/8" casing, and when fully hydrated will seal holes up to 2.8". The 1-1/4" and 2" models fit in 3" and larger holes and seal up to 3-3/4". 30" long units stack for longer seals.
