2. No personnel working on the geogrid shall smoke, wear damaging shoes or engage in
other activities [hat could damage the geogrid.
3. On slopes, the geogrid shall be secwely anchored and then rolled down the slope in
such a manner as to continually keep the sheet m tension.
4. Geogrid panels shall be deployed in such a manner as to preclude wrinkles and folds.
5. Geogrid within the lined area shall be cut with a cutter approved by CC&V, such as
scissors. Unshielded razor knives are not acceptable.
6. Two layers of geogrid shall be installed as indicated on the Drawings. The layers will
be placed at right angles to each other as dvected by the CERTIFYING ENG WEER.
7. The subgrade shall be prepared for geogrid placement by uniform grading. No steep
grade changes or edges shall be allowed. The CERTIFYING ENGINEER shall
approve the subgrade prior to geogrid installation. The subgrade must not be smooth
rolled.
B. Joining
I. The geogrid shall be placed in continuous pieces downslope.
2. If the geogrid is to be joined end to end, a pinned connection splice shall be used. The
pinned connection must be manufactured from FIDPE materials and shall be
manufacrurer approved.
C. Defects and Repairs
• 1. All damaged geogrid rolls shall be rejected. No repairs shall be made.
3.03 PLACEMENT OF SOIL OR GRANULAR MATERIALS:
All soil materials located on top of a geogrid shall be placed in such a manner as to enswe:
1. The geogrid is not damaged.
2. Minimal movement and wrinkling or folding of the underlying geogrid layer(s) occurs.
3. No excess tensile stresses shall occw in the geogrid such as when earth moving equipment makes
sudden starts, stops, or toms.
4. Soil placement over the geogrid shall be performed with constmction equipment approved by the
CERTIFYING ENGINEER. Such construction equipment includes low to moderate ground
presswe dozers (e.g., D-6 or D-8 CAT dozer). Dozers will push soil materials over the geogrid
from the bottom of the slope in an uphill direction.
5. A minimum of 6" of soil cover shall be placed over the geogrid layers. No construction
equipment shall operate directly on the geogrid layer or on less than 6" of soil cover.
6. Soil cover over the geogrid shall consist of Select Stmcrural Fill and shall be compacted and
placed according to Select Stmctural Fill SPECIFICATIONS in Section 2200.
7. Extent of geogrid reinforced areas shall be surveyed and staked in the field by the CONTRACTOR.
Subsequent construction activities over the reinforced areas shall not damage geogrid or reduce soil
. cover thickness to less than 6 inches.
