Section 2

Product Specification - Structural Geogrid BX1200
The structural geogrid shall be an integrally formed grid structure manufactured of a stress resistant polypropylene material with molecular weight
and molecular characteristics which impart: (a) high resistance to loss of load capacity or structural integrity when the geogrid is subjected to
mechanical stress in installation; (b) high resistance to deformation when the geogrid is subjected to applied force in use; and (c) high resistance to
loss of load capacity or structural integrity when the geogrid is subjected to long-term environmental stress.
The structural geogrid shall accept applied force in use by positive mechanical interlock (i.e. by direct mechanical keying) with: (a) compacted soil or
construction fill materials; (b) contiguous sections of itself when overlapped and embedded in compacted soil or construction fill materials; and (c)
rigid mechanical connectors such as bodkins, pins or hooks. The structural geogrid shall possess sufficient cross sectional profile to present a
substantial abutment interface to compacted soil or particulate construction fill materials and to resist movement relative to such materials when
subject to applied force. The structural geogrid shall possess sufficient true initial modulus to cause applied force to be transferred to the geogrid at
low strain levels without material deformation of the reinforced structure. The structural geogrid shall possess complete continuity of all properties
throughout its structure and shall be suitable for reinforcement of compacted soil or particulate construction fill materials to improve their long
term stability in structural load bearing applications such as earth retention systems. The structural geogrid shall have the following characteristics:

meters (13.1 feet) in width and 50.0 meters (164 feet) in length. A typical truckload quantity is 165 to 220 rolls. On special request, the structural geogrid
may also be custom cut to specific lengths or widths to suit site specific engineering designs.
Notes
1. Unless indicated otherwise, values shown are minimum average roll values determined in accordance with ASTM D-4759. Brief descriptions of test
procedures are given in the following notes. Complete descriptions of test procedures are available on request from Tensar Earth Technologies, Inc.
2. Nominal dimensions.
3. True resistance to elongation when initially subjected to a load measured via ASTM D6637 without deforming test materials under load before measuring
such resistance or employing "secant" or "offset" tangent methods of measurement so as to overstate tensile properties.
4. Load transfer capability measured via GRI-GG2-87. Expressed as a percentage of ultimate tensile strength.
5. Resistance to bending force measured via ASTM D-5732-95, using specimens of width two ribs wide, with transverse ribs cut flush with exterior edges of
longitudinal ribs (as a "ladder"), and of length sufficiently long to enable measurement of the overhang dimension. The overall Flexural Stiffness is
calculated as the square root of the product of machine-and cross-machine-direction Flexural Stiffness values.
6. Resistance to in-plane rotational movement measured by applying a 20 kg-cm moment to the central junction of a 9 inch x 9 inch specimen restrained at its
perimeter (U.S. Army Corps of Engineers Methodology for measurement of Torsional Rigidity).
7. Resistance to loss of load capacity or structural integrity when subjected to mechanical installation stress in clayey sand (SC), well graded sand (SW), and
crushed stone classified as poorly graded gravel (GP). The geogrid shall be sampled in accordance with ASTM D5818 and load capacity shall be measured in
accordance with ASTM D6637.

PART 3 – EXECUTION
3.01 Site Excavation
A. The contractor shall excavate the site to the width, depth and length necessary to accommodate and
install the CUDO stormwater system including provisions for cover over the system and depth below
the system in accordance with the project engineer’s specifications.
B. Examine prepared excavation for smoothness, compaction and level. Do not start installation of CUDO
cubes until unsatisfactory conditions are corrected. Check for presence of high water table, which must
be kept at levels below the bottom of the CUDO structure at all times.

CUDO Technical Specifications
C. Installation constitutes acceptance of existing conditions and responsibility for satisfactory performance.
If existing conditions are found unsatisfactory, contact Project Manager for resolution.
3.02 Base Preparation
A. Generally a base material of sand or stone should be used and be compacted to 95%. The specific
nature of the material will depend upon a myriad of factors, including but not limited to soil reports
and end use of system (detention or retention). The base must be finished evenly to provide a level
surface for the CUDO installation.
B. It is helpful to identify the outline of the structure on the floor of the excavation, using spray paint or
chalk line, to ensure squareness during cube placement.
3.03 Installation of CUDO Cubes
A. Either a non-woven filter fabric material or an impermeable liner will be required to surround the
perimeter of the CUDO system. Either product shall be laid to the contour of the excavation bottom and
side walls with a minimum of 12” overlapping, or as specified by the project engineer.
B. The assembled CUDO cubes shall be placed on top of the fabric/liner material in accordance with the
project’s specific layout details. Maintain a level top at all times and keep the units in a straight line in
each direction. Complete any inlet/outlet pipe connections in accordance with the project’s details.
Connect the inspection/cleanout port riser material to the top of the CUDO as shown on the project
layout detail. Pull the fabric/liner material taut around the CUDO cubes to completely seal the system,
using duct tape to temporarily secure the material overlaps in place.
C. Start backfilling with recommended backfill, compacting in 12” maximum lifts. Place backfill carefully to
avoid shoving or damaging cubes. Use a powered mechanical compactor to compact backfill on
structure sides with care to avoid damage to geotextile or liner.
D. Backfill above system should be compacted in 6” lifts. When backfill reaches an elevation 12” above the
system, place a layer of geogrid directly over the top of the backfill (required only when there will
be traffic loads (H20 loads) above the cubes), extending 3’ beyond the cube footprint.
E. Place sufficient backfill (Section 2.02 E) material over geogrid to ensure support of design loads. Place
cover backfill in 6” lifts and compact with vibrating plates or walk behind rollers (do not use drivable
rolling compactors) to a minimum of 95% compaction. Take care to place backfill on top of structure to
avoid damage to structure, geotextile or liner, using low pressure tire or track vehicles.
F. Ensure that all unrelated construction traffic be kept away from the limits of excavation until project is
complete and final surface materials are in place.
G. Place surfacing materials, such as groundcovers (no shrubs or trees), or paving materials over the
structure with care to avoid displacement of cover fill and damage to surrounding areas.

CUDO Technical Specifications
3.04 Cleaning
A. Perform cleaning during the installation of work and upon completion of the work. Remove from site all
excess materials, debris, and equipment. Repair any damage to adjacent materials and surfaces
resulting from installation of this work.
