Dear Mr. Rockwell,
CONTECH Construction Products, Inc has provided DuroMaxxlM Steel Reinforced Polyethylene pipe for
the subject project. DuroMaxxTM is manufactured to meet the requirements of ASTM F2562 and
AASHTO Designation MP-20. DuroMaxxTM exceeds all of the critical performance parameters of
unreinforced high density polyethylene pipe (AASHTO M294 designation):
Raw Materials - DuroMaxxTM is manufactured with HDB (Hydrostatic Design Basis) pressure
rated resins meeting the requirements of cell classification 345464C per ASTM D 3350. These
resins provide up to 35 times the stress cracking resistance when compared to the resins used in
unreinforced HDPE pip.
Structural Capacity - DuroMaxxTM has a minimum height of cover of one foot for diameters up to
60 inches and a maximum height of cover of 50 feet for diameters up to 42 inches. The
maximum height of cover for DuroMaxxTM can be as much as four times the maximum height of
cover of unreinforced HDPE pipe.
In Place Stiffness - When tested in a temperature controlled lab DuroMaxxTM has similar
stiffnesses when compared to unreinforced HDPE pipe. The critical performance parameter
relating to stiffness and thus deflection is in place stiffness. The amount of stiffness loss
experienced by unreinforced HDPE pipe can be dramatic on a relatively warm day when
conditions don't match the conditions in the temperature controlled lab. Even on a 90 degree day
the surface of black pipe can exceed 130 degrees. As evidenced by the chart below unreinforced
HDPE pipe can lose up to 50% of its stiffness at 130 degrees while DuroMaxxTM, due to its steel
reinforcement, loses less than five percent of its stiffness. The higher in place stiffness will assist
in achieving compaction faster without over deflecting the pipe.

Joint Integrity - DuroMaxxTM is manufactured with a steel reinforced bell and spigot joint. In order
to develop a watertight connection it is necessary to significantly compress the gasket in the joint.
This creates considerable stresses in the bell and the spigot. By itself, high density polyethylene
is susceptible to creep when placed under the stresses typically created by gasket compression.
AASHTO M294 pipe does not have reinforcement in the bell or spigot. Over time, this results in a'
relaxation of the gasket compression as the bell and spigot creep away from the gasket. When
tested in lab conditions for 10 minutes unreinforced HDPE pipe is rated to an internal pressure of
10.8 psi. It is very likely that the pressure capacity of an unreinforced joint will drop off
considerably as the bell and spigot relax. DuroMaxxrm is manufactured with a steel reinforced
bell and spigot and tested to an internal pressure of 15 psi per the protocols of ASTM D 3212.
Since steel is not susceptible to creep this joint capacity is maintained long term.
As with almost all flexible pipes, DuroMaxxTM is installed per the requirements of ASTM D 2321. This is
the same installation method referenced by most manufacturers of unreinforced HDPE pipe. DuroMaxxTM
is designed using a modified version of AASHTO LRFD Section 12. Since the vast majority of the
structural. capacity of DuroMaxxTM is derived from its steel reinforcement it is appropriate to use a steel
pipe design I methodology. We can provide independent full scale load testing that verifies the accuracy of
this design methodology. The modified design methodology is currently under review by AASHTO's
Bridge committee.
Please do not hesitate to contact me if you have any questions or need clarification on anything
presented here.

Trench Dimensions
renching practices shall be in accordance with OSHA-.'
The trench needs to be wide enough for aperson
to work safely.
Where trench walls are unstable, the contractor
may elect to use tight sheeting, stay bracing, or a
trench box for stabilization during pipe laying. If
the conditions are severe, sheeting may be left in
place.
Refer to ASTM D2321, Paragraph 6.4.2, for proper.
placement and movement of-trench boxes.
Improper use of trench boxes can affect pipe
performance.
Groundwater •
1 Excessive groundwater may necessitate
dewatering. Dewatering techniques must meet all •
OSHA and local requirements and codes.
2. In areas of saturated trench conditions or in •
dewatered trenches, refer to page 9, "Foundation
-and Bedding," and ASTM D2321 for proper. selection
of bedding and backñll.materials. .
3. Flotation of the pipe and erosion or wash-oUt, of
previously plated soil support must be prevented
to ensure that the structure maintains its load
carrying capacity. • • •
4. Contact the Engineer of Record, hereinafter •
referred to as "engineer:' for proper cover to'prevent •
flotation.
•
•
Foundation and Bedding
1. An Unstable trench bottom must be stabilized
at the engineer's direction. In such cases, install
special foundation and bedding materials in 6 inch
layers and compact.
Excavation from 6 inches to 12 inches below-the
pipe should be filled with acceptable bedding
material and compacted to a minimum 90%
Standard Proctor Density. Fill areas Of over
excavation beyond 12 inches with processed
stone or-gravel following standard bedding
practices.
The bedding material provides uniform support
to hold the pipe on line and grade., A relatively
loose 4-inch to 6-inch thick bedding layer is
usually adequate. Before installing the pipe, bring
bedding material to grade along the entire length
of the pipe. A flat shovel can be used to level the,
surface to grade. Bedding materials can be Class I,
III III (ASTMD2321) • ' '
When excavating in Class IV materials (silts, silty
' clays and clays), provide a uniform, undisturbed
' ' foundation.
5. Class IA materials if used for,bedding, must be
used as haunching material to the spring line
in a dry trench. To minimize the potential for
' migration, Class IA materials should be used to the
'top of the pipe in wet trenches or in trenches that
' ' • will fall below the water table. ' •

Assembly of Pipe (Joining)
DuroMaxx features a bell and spigot.to connect
the pipe and unless otherwise directed by the
Engineer,, should be placed with the spigot end
facing downstream.
Remove the protective film from the gasket prior
to applying the lubricant or joining the pipe.
The double sealing surfaceof DuroMaxx WT
gasket is fitted into the spigot valleys as shown
in the drawing below. lfthe gasket is removed,
make sure the gasket seat is clean and then
reinstall properly. S
Make sure the bell and spigot is thoroughly clean
and free of soil of any type.
Bell & Spigot Joiflt
t,c1TrT
Typical details of a reinforced bell and spigot joint for
DuroMaxx WT Steel reinforcement is in the bell only, for,
silt tight (ST) joints.
Use a Johnny mop or brush to apply a liberal
amount of gasket lube to the gasket and to swab
the inside of the bell. S
Dig out a"bell hole" along the bell end's edge
with a shovel or boot heel in order to keep the
spigot freeof bedding material and to prevent
materials from being pulled into'the bell by the
spigot. Materials pulled in can impair .gasket
sealing and cause leaks.
Align the spigot end of the pipe into the bell's
leading edge during joining process - being
careful not to allow soil or debris .into the
connection.
Do not push on the bell end of the pipe! Do not
use a cable or chain wrapped around the pipe
to join the pipe. Use of a nylon strap to pull the
pipe is strongly advised.
10
9. The spigot end of the pipefeatures a "horning
mark"that will align with the end of bell when
the spigot has been fully inserted into thebell.
10. Once the pipe has been fully placed in the trench
and prior to backfllling, it is recommended that
the Engineer bra qualified representative of
the Engineer approve the trench, bedding and
. placement of the pipe.
. 11. Cold Weather Note: Rubber gaskets become
harder as the ambient temperature decreases.
Gaskets tend to compress less, and when
combined with bells, jointing becomes less,
forgiving,Proper bell-spigot alignment,
adequate bell and spigot lubrication and
recommended.joining procedures all become
more essential as temperatures decreases.
12. After. proper assembly,-take precautions to
prevent the pipe from movement prior to
haunching and backfllling.
Haunching . • • •
Proper haunching provides a major portion
of the pipe's load-carrying capability.. Poor
workmanship will lead to excessive pipe
deflection and grade and alignment problems.
Haunching materials can beClass I, II, or Ill per
ASTM.D2321. • •
Work enough material underthe haunch of the
pipe by hand to provide proper compaction and
side support. Material shall meet theminimum
compaction requirements of ASTM D2321.
When trench walls are unstable, sloughing must
be prevented so that haunching material can be
placed and compacted adequately. The proper
use of a trench box or overexacvation can assist
•in these cases. : •
4. Don't let the pipe move when placing material
. under the -haunch of the pipe.
11
5. Take .care not todamage the pipe with thovels, or
other construction/tamping equipment. *
6. Haunch materialextends from the bedding/
foundation material to the springline elevation
Backfill and Compaction . ..
S
1. Initial backfill niateria Is. extend. from. the
springline to inches to 12 inches above the pipe,
to provide the remainder of the pipe support
and protect the pipefrom stones or cobbles in

FlOwable Fill .
These materials are suitable for use with DuroMaxx
at the direction of the Engineer. The contractor
must. take precautions to preckide the dislocation .. . .
or flotation of the pipe during placement of the
flówable fill. Should these materials be utilized . .
by the contractor, CONTECH Will assist with ,
recommendations for restraint to ensure line and . .'
grade, can be maintained. . .
.
. . .
Embankment Conditions . . .
DuroMaxx is superior product that is normally .
installed in a trench condition. Embankment
installations are an acceptable installation
application.
.
. . . . .
In general, the backfill type and placement of the
backfill immediately around the pipe can bethe
same as that shown on pages 14 and 15. . -
The width of the select fill zone aroundthe pipe
and thetype of material placed outside the zone
- adjacent to the select fill zone - are critical and
dependent upon the pipe diameter and ultimate . .
amount of fill, and loads to be placed over the
Pipe. . .
In the event of an embankment installation, a
backfill design should be prepared for the specific
site conditions by the Engineer.
Larger diameters may not be allowed or may
require additional care in backfilling. Only small
walkbehind compaction equipment should be,' '
0
used directly around the pipe.,,
Cover Limits
Once the backflhling process is completed, the
contractor should take care to maintain the
minimum allowable cover height over the, pipe
and should, notify all other contractors and.
subcontractors to avoid removal of fill cover or
rutting.

NOTES
Allowable minimum cover is measured from the top
of the pipe to the bottom of a flexible pavement or
the top of the pipe to the top of a rigid pavement.
Minimum cover in unpaved areas will be greater
than for paved areas shown in Table 2 and must be
maintained. Contact your local CONTECH Sales
Engineer for more information.
All heights of cover are based on trench conditions.
If embankment conditions exist, additional care in
the placement of fill outside the pipe backfill zone is
required. Your CONTECH representative can provide
further guidance for a project in embankment
conditions. .

Joint Testing
Be sure to apply lube to the spigot gasket and the
inside of the bell of every joint made to ensure a
proper connection. Do not pull debris into the bell
along with the lubricated spigot. A bell hole may be
needed in order to achieve this. All pipe must be free
of damage of any kind..
Temperature Effects
1. DuroMaxx is a superior product and the pipe's
' stiffness is not affected by solar absorption or
elevated ambient temperatures. •
• '• 2. If large swings in temperature occur from the
•
• location the pipe is stored andthe bottom-of the
trench, then the pipe may require conditioning to
• avoid contraction of the pipe's'length. •
Manhole or Structure Connections S
DuroMaxx can be connected to manholesor other
•. types of structures using typical methods used by
other flexible pipe products. Please consult the
Engineer and your local CONTECH Sales Engineer '
S •5 to discuss what method is most appropriate for the
S application.

Cutting Instructions
The recommended cutting tool for DuroMaxx pipe
is a chop saw and abrasive saw blade. Refer to the
Operating Instructions from the saw manufacturer
for additional information. .
Blade thickness should be nolessthan 1/8"thick
and is recommended to be made of 2 ply material
that is used to cut ductile iron pipe
3 Use the leading edge of the blade to cut into the
ribs of the pipe
Bury the blade as much as possible into the pipe
as you proceed
The alternative cutting toblfor DuroMaxx i5a
handheld reciprocating saw. This process will take
about 2 minutes to cut the steel ribs. There are 9
ribs for 24" around the pipe circumference.
Always use safety glasses when cutting
DuroMaxx pipe and use protective gloves
incasé sharp edges are exposed..
20
Repairs
Should damage to the pipe occur at any, point
during installation, the Engineer should be
contacted immediately. . .
For larger damaged sections, cut out-damaged
areas and cut a length of replacement pipe to fit.
Similar to other flexible pipe products, DuroMaxx
can be coupled 'using various industry standard
methods and materials. .' . .
For smaller abrasions or exposed steel, an
approved rubberized undercoating, spray can be
used to cover the steel.
Contact your local CONTECH. Sales Engineer
if you have any questions or concerns and for
recommendations.
Taps
DuroMaxx pipe can be supplied with standard
prefabricated taps fittings' or components pe.rjob

A STEEL REINFORCED POLYETHYLENE PIPE
DuroMaxx® Specification. Sheet
Scope
This specification describes DuroMaxx® pipe for use such as storm sewers, sanitary sewers, industrial waste
applications, drainage pipes, underground detention, infiltration, cistern or rainwater harvesting systems in 24"
(600 mm) through 120" (2400 mm) nominal diameters.
Description.
DuroMaxx is a reinforced polyethylene pipe with a smooth waterway. wall and exterior profile that is reinforced
with high strength galvanized steel ribs. The continuous reinforcing ribs are completely encased within the
polyethylene profile. DuroMaxx is manufactured using a helical winding process that results in a continuously
fusion welded lap seam. The pipe profile is manufactured using a high quality stress-rated thermoplastic
meeting the requirements of ASTM F2562 "Standard Specification for Steel Reinforced Thermoplastic Ribbed
Pipe and Fittings for Non-Pressure Drainage and Sewerage" or AASHTO Designation MP-20. For the purpose
of hydraulic design, the recommended Manning's "n" value shall be 0.012 for pipe diameters included within this
specification.
Material Properties . . . .
Virgin high density polyethylene stress-rated resins are used to manufacture DuroMaxx pipe and complimentary
fabricated fittings. Resins shall conform to the minimum requirements of cell classification 345464C as defined
and described in the latest version of ASTM D3350 "Standard Specification for Polyethylene Plastics Pipe and
Fittings Materials".
Joint Performance
Pipe lengths shall be joined on site using coupling bands, bell & spigots or ElectroFusion couplers especially
designed for DuroMaxx pipe. Joints shall meet one of the performance levels as required and specified:
Soil Tight Joints (24" - 96") shall be plain ended DuroMaxx pipe with Aluminized Type 2 (or optional
Polymeric coated) CMP coupling bands and elastomeric gaskets (see Standard Drawings 1012802).
Low Head (LH) Joints (24" - 72") shall be gasketed, stress-rated high density polyethylene bell and
spigot joints (meeting the requirements set-forth in the above Material Properties paragraph) that have
been laboratory tested to 3 psi when tested in accordance with ASTM D3212 "Standard Specification for
Joints for Drain and Sewer Plastic Pipes Using. Flexible Elastomeric Seals" (see Standard Drawing
1012803). . .
High Performance (HP) Joints (24" - 72") shall be gasketed, bell and spigot joints where both the bell
and spigot are reinforced with steel that is fully encased in stress-rated high density polyethylene
(meeting the requirements set forth in the above Material Properties paragraph) and that have been
laboratory tested to 15 psi when tested in accordance with ASTM D3212 "Standard Specification for
Joints for Drain and Sewer Plastic Pipes Using Flexible Elastomeric Seals" (see Standard Drawing
1012804).
ElectroFusion (EF) Joints (36" - 120") shall utilize plain ended DuroMaxx pipe welded together
utilizing exclusive pressure testable ElectroFusion couplers. The welded connections provide a true in-
field watertight system assured by the pressure testable welded sleeves at each welded connection.
The field installed ElectroFusion joints shall remain watertight with a "zero" leakage rate up to a test
pressure of 30 psi (see Standard Drawing 1012805). . .
Fittings • . .
All fabricated fittings and couplings supplied by the manufacturer shall be constructed to ensure no loss of
structural integrity or joint tightness at welded seams and joints. Only those fittings supplied by or recommended
by the manufacturer shall be used.
Installation
Installation shall be in accordance with ASTM D2321 "Practice for Underground Installation of Thermoplastic Pipe
for Sewers and Other Gravity-Flow Applications" along with product-specific recommendations contained in
Cohtech Installation Guidelines for DuroMaxx pipe, available from local Contech representatives or from
www.contech-cpi.com.
