Stratagrid Geo Grids

Read More...

Can I connect Strata geogrid using a bodkin connection or rebar?

No. Knitted and woven geogrids lack junction strength and will pull apart at the junctions. Junction strength is not required in uni-axial geogrids. The cross machine direction is there only to orient the machine or strength direction. As such, there can be no overlapping or connecting lengths of Stratagrid in the machine or roll direction.

Can I roll out Stratagrid along the length of a straight wall?

With the exception of SG 150, Strata geogrids are uniaxial (strength in one direction.) As such, they must be rolled out perpendicular to the wall face.

Do I overlap Strata geogrid?

No. Overlapping can cause slipping. Just butt the two pieces together side to side. There can be no overlapping or connecting lengths of Stratagrid in the machine or roll direction.

How do I install geogrid on a curve or radius?

Geogrid needs to have 100% coverage around any curve. For INSIDE CURVES, lay out the primary geogrid around the curve butting front edges together. Make sure strength direction runs perpendicular to wall face. Mark the blocks or take note of the areas where there are voids in the grid placement. Additional layers need to be installed above the course where the geogrid is required to fill voids that are created. For OUTSIDE CURVES, lay out the geogrid around the curve. Lift the section of grid that overlaps and place the fill material to separate. Grid layers need to be separated by a 3 in. (75 mm) layer of approved fill material. Never compact directly on the geogrid.

Stratagrid Geo Grids

US Fabrics is pleased to offer Stratagrid, the only precision knitted geo grid available in the market today. The Strata manufacturing process insures superior quality, consistency and dimensional stability. Strata geogrid offers superior junction integrity and a higher coefficient of soil interaction compared to any other polyester geo grid. Stratagrid is the standard by which all other geogrid products are measured.

  • Only Precision Knitted Geogrid
  • Consistent & Stable
  • Superior Junction Integrity
  • Higher Coefficient of Soil Interaction

Segmental Retaining Walls with Stratagrid

Segmental retaining walls provide unmatched outer beauty. Reinforcing the retained soil mass with Strata geo grid provides superior internal strength. These structures can be designed to uphold even the most stringent of project requirements. Walls reinforced with Strata geogrid provide an aesthetically pleasing, quick and cost-effective alternative to conventional poured-in-place and cantilever retaining walls.

Conventional site retaining walls, landscaping walls, stream channelization, bridge abutments, and tiered architectural walls are all acceptable applications for Strata geo grid. Using Stratagrid in these structures will help reduce site development costs, allow for design variability, minimize foundation preparation and result in rapid, simple construction.

Slope Reinforcement with Stratagrid

Increasing useable land has become an important economic factor in property development. Developers and designers faced with the challenge of maximizing land use often encounter difficult topographic characteristics and soil conditions.

Slopes reinforced with Strata geo grid can be constructed more steeply than the soil's natural angle of repose, eliminating costly facing elements and substantially increasing useable land. In addition, they offer the site engineer the flexibility to create stable structures that fit the natural contours of the land. Strata geo grid is layered within the compacted soil to create a reinforced soil composite that has high internal stability.

Strata is excellent for reinforced steepened slopes, surficial stability of embankments, stream channelization, embankments constructed over weak soils, levees, temporary walls, pressure relief walls and bridge abutments.

Microgrid Facing Geogrid

Strata MicroGrid is a geogrid designed to work as part of the facing and as a secondary reinforcement when constructing a reinforced slope with welded wire facing units. The Microgrid confines aggregate or soil within the facing units. Because of Microgrid's unique apertures, the use of a TRM when vegetating the face may not be necessary. Stratagrid is used as the primary reinforcement. Please see the "Bank of Kentucky" project under our "Case Studies" tab for more information on this type of structure.
