Structure Guard GeoForm Bags

Structure Guard GeoForm Bags represent a revolutionary step in the technology of underwater grout bag repairs. Our spun bond polyester weave provides the strength and durability for both temporary and permanent repairs. A pumping port, centrally located, is sewn in place to self seal upon removal of the injection pipe. The porous mesh permits the excess water to bleed off resulting in a high quality grout installation.

Where the bags are used as forms for void repairs, they can be stacked and pinned together with rebar. Pumping and relief ports are installed into the void area to permit complete filling of the undermined section. Bags can be pumped 18" to 24" thick.

For armor plating of river or stream bed to fill scour holes and line the channel, the bags can be pumped 6" to 8" thick with bags laid edge to edge.

Where rip rap placement is called for on small bridges, the bags provide a very low cost method of scour protection. Typically, a three man crew and a small grout pump, i.e. Mayo Pump, is all that is required for production pumping of 15 to 20 cubic yards in a day. GeoForm Grout Bags tend to lay flat for easy diver placement, without the floating and twisting associated with other products. Our GeoForm Bags are approved for bridge repairs by various state DOT's throughout the northeast.
