7 Series Geogrid Instructions

  1. Follow Retaining Wall Instructions
    • Follow the installation instructions supplied with the retaining wall system including foundation preparation, block alignment, core filling, drainage rock placement, backfill placement, and compaction.
    • Place the next course of block on top of the geogrid.
    • Eliminate any folds or looseness in the geogrid by pulling tight and staking at the back.
  2. Backfill, Compact, & Repeat
    • Backfill must be compacted and level with the top of the retaining block course prior to installation of geogrids. The geogrid should start near the face of the block and remain in one continuous piece to the back of the reinforced soil mass (no splicing). ­Butt together at edges — do not overlap g­eogrid.
    • Backfill and compact the soil to 95% standard proctor. Always backfill and compact one course of block at a time. Keep an adequate cushion of soil between the geogrid and equipment.
    • Repeat process until retaining wall is completed.

Landscaping Supplies FAQs

Solvent-based adhesives offer extreme temperature flexibility, bonding effectively to frozen surfaces down to 10°F as well as wet block. Polyurethane adhesives provide rapid initial grab and fast cure times on dry or damp block, though they should not be used on plastics, rubber, or underwater applications.

Bi-directional geogrids (Universal and 3 Series) distribute stress across both length and width, making them ideal for retaining walls up to 6 to 10 feet tall. Uni-directional geogrids (5 Series and 7 Series) concentrate maximum tensile strength in a single direction to reinforce tall segmental retaining walls up to 15 feet high under heavy soil loads.

Lay the geogrid flat starting near the face of the block course and extend it in one continuous piece to the back of the reinforced soil mass without splicing or overlapping. Pull taut, stake it at the back, and compact backfill soil to a 95% standard proctor before placing subsequent block courses.

A 10 oz tube covers roughly 14 feet with a 3/8 inch bead or 32 feet with a 1/4 inch bead. A 28 oz tube provides about 35 feet of coverage with a 3/8 inch bead or 89 feet with a 1/4 inch bead.

Yes. SRW solvent-based adhesives bond directly to wet stone and frozen surfaces as cold as 10°F without requiring surface primers.
