GEOFORM®: A REVOLUTION IN GROUT BAG TECHNOLOGY
Our spun bond polyester weave provides the strength and durability for both temporary and permanent repairs. A centrally-located pumping port is sewn in place to self-seal upon removal of the injection pipe, while the porous mesh permits excess water to bleed off—resulting in a high-quality grout installation.

Structure Guard bags are lighter-weight than any we've used in the past. Unlike the poly bags that slip and move all over, these stay in place with minimum staking necessary and are 1/3 the cost of poly! Our two-day job turned into not even a full day! My divers words were "These bags are awesome." Next job, we're getting them again.

For many years the State of Maine Dive Team has used Structure Guard GeoForm bags manufactured in Rockland for scoured areas around, under, and in front of bridge abutments and as slope protection—and we are currently considering a seawall application. We have found that these bags are our best option for short-term solutions, extreme emergency repairs, and permanent repairs.

I was thoroughly impressed with Structure Guard’s easy-to-use design and installation guide, ability to provide in-stock options for emergency repairs, and otherwise short turn-around times for custom needs—I won’t hesitate to contact you again on future projects!
