Site Preparation
Prepare Subgrade Layer
Prepare subgrade per construction drawings or Engineer.

1.   PREPARE SITE AND SUBGRADE.
     a) Clear and grub vegetative cover, debris, stumps, roots.
     b) Replace unacceptable foundation soils if specified.

2.   COMPLETE EARTHWORK.
     a) Level surface to planned elevations and grades.
     b) Compact subgrade according to specifications.




                                                                        FIGURE 5. PREPARE SUBGRADE LAYER



Layout Geotextile / Geogrid (if specified)
1.   Install geosynthetic layers according to the manufacturer’s
     directions.

2.   Ensure required overlap between rolls or pre-sewn seams
     according to project specification.




Anchor Stakes

Anchor Stakes along Route                                                      FIGURE 6. LAYOUT GEOTEXTILE


     NOTE: Take care not to damage underground
     infrastructure such as geomembranes, cables or pipes.

Stakes or pins are used to position and anchor the outer cells of
the Neoloy sections prior to infill. Use pointed wood, iron or
steel j-hooks according to the subbase hardness.

1.   Anchor the stakes firmly in the ground.
     a) Geotextiles (if applicable) – penetrate the geotextile
        fabric with the stakes; or if a non-permeable
        geomembrane is used, anchor the stakes on the sides.
     b) Intervals – typical spacing between stakes is ~50 cm
        when fully opened; depending on the cell size, project
        specifications, or on-site Engineer.
                                                                    FIGURE 7. INSERTING STAKES/ANCHORS ALONG ROUTE
     c)   Marking - string or chalk line may be used to align
          staking locations and borders.

     NOTE: Leave at least 10 cm of the stakes exposed as they will be removed before compaction and paving.
