The Maine Department of Transportation is very familiar with the GeoForm grout bag mattresses manufactured by Structure Guard, Inc. For many years GeoForms have been purchased and installed by MaineDOT’s Dive Team and various highway contractors. The GeoForms have been installed to repair scour areas under and around bridge abutments and piers.
    The GeoForms have been supplied in various stock and custom sizes and all have performed as expected. We are absolutely satisfied with their performance and will continue using this product in the future.

Carl Edwards, Dive Manager

Beaty Construction, Inc.

I would like to personally thank you for your assistance with our emergency bridge repair. 
    You provided excellent design and installation information as well as general guidance for a quick emergency project. You did this all with very little notice and a very tight schedule.
    The directions you gave for the grout bags made for a quick and easy installation. Even though you had enough supply on stock to fulfill my order, I appreciate how quickly you would have been able to get more for us.
    Overall, I was impressed with your organization and won’t hesitate to contact you again for assistance on future projects.

Say About Our Grout Bags 

Able Diving Co.


The bags worked great! 
    They are lighter weight than the grout bags I've used in the past. Unlike the poly bags that slip and move all over on the bottom, and usually have to be staked down with re-steel when filling with grout. Your bags stay in place and a minimum of staking has to be employed. Also these bags were one third the cost of poly.
    Two day job turned into not even a full day. Was home a little after noon.
    Summing this up my divers words were, "These bags are awesome." Next job, get them again.
    The whole Able Dive Crew thanks you again.
