VERSA-Grid is lightweight and easy to install. It’s flexible, with virtually no memory, so it lays flat after being unrolled. Just unroll and make sure the VERSA-Grid is rolled out continuously, perpendicular to the wall face. Telecharger windows 7 titan 32 bits iso 9000.

VERSA-Grid comes in multiple strength types. VERSA-Grid 3.0, VERSA-Grid 5.0 and VERSA-Grid 8.0 are the strengths commonly used for landscape and commercial walls. These VERSA-Grid strengths are generally available in 6-ft.

Wide x 150-ft. Long rolls (100 sq.yd. For some residential walls, VERSA-Grid 1.5 is used, but only for walls up to 6 feet tall. It is available in 4-ft. Wide by 50-ft long rolls (22 sq.yd. Estimating Geogrid Quantities The length, vertical spacing, number of layers and strength of the geogrids needed will vary with each wall project, depending on wall height, loading, slopes, and soil and water conditions. Retaining walls taller than 3 to 4 feet typically require a qualified professional civil engineer (P.E., licensed in the state of the project) to prepare a project-specific, final wall design that shows the needed geogrid based on actual site conditions.

Consult with a local building code official regarding permitting and wall design requirements. VERSA-LOK and local VERSA-LOK representatives can provide contacts for engineers with segmental retaining wall design experience who are licensed in your state. For preliminary geogrid estimates, your local VERSA-LOK representative can assist in estimating geogrid lengths and quantities. VERSA-LOK’s can also help in preliminary estimates of geogrid quantities. The for each type of VERSA-LOK unit also includes VERSA-Grid estimating charts for that unit type, for common site conditions.

This installation guideline applies to Tensar TriAx geogrids supplied by Tensar International or any of its appointed distributors. It provides a guideline for.

Step 1 The wall installation, including geogrid installation, should be done in accordance with the project-specific final wall design and specifications, prepared by a qualified, licensed professional engineer (P.E.) and any applicable building codes and standards. Prepare to install VERSA-Grid by placing VERSA-LOK units, backfilling and properly compacting soil fill and up to the height of the first (lowest) soil-reinforcement layer that is specified on the final, professionally engineered construction drawings (P.E. Stamped plans) (Figure 1, below). Several layers (lifts) of soil fill will need to be placed and then compacted to reach the height of the first geogrid layer elevation. Note that the maximum allowable thickness for loose soil lifts, before compacting, varies with type of backfill soil and equipment used.

Step 3 Placing geogrid behind curves and corners requires special layout and overlapping procedures. Never overlap geogrid layers without soil in between the layers; always provide at least three inches of soil fill between overlapping geogrid layers.
