                      Dear NASSCO Times Readers:

 As the rehabilitation industry continues to grow so does NASSCO’s membership. I am
 seeing an influx of new members seeking to learn more about the industry, offering to par-
 ticipate in the NASSCO programs and networking with the other members. This illustrates
 to me that being a member of NASSCO offers you the ability to educate yourself on the
 latest industry trends; participate in cutting edge technology programs; steer the direction
 of the industry through participation on specific committees or playing an active role in a
 Division; or networking with the wealth of human knowledge that currently is available at

  The secret to NASSCO’s continuing success is a dedicated staff and active members who bring their personal
  knowledge to get things done. This core group of active members however needs help for NASSCO to con-
  tinue its growth and service to the industry. I urge new members to assume leadership roles in NASSCO. So
  ask yourself, why should I do anything more than just be a member? The answer is simple. Playing a leader-
  ship role gives you first hand knowledge of cutting edge technologies and programs being developed; allows
                              you to network with key industry leaders on issues of common interest; and pre-
“Playing a leadership role    sents you with knowledge that will enhance your own career or open up new busi-
gives you first hand          ness opportunities.
knowledge of cutting edge
                               NASSCO’s mission is to support its members with a variety of programs and ser-
technologies and programs
                               vices but most importantly we promote programs that will result in business op-
being developed...”            portunities. So the next time you ask yourself what else there is, take a leadership
                               role in NASSCO which could enhance and advance your own career.

 In the upcoming months many of NASSCO’s efforts will come together. These efforts include: adoption of a
 5 year plan; new member services including an extensively improved web site; new divisions now in their
 formative stage; advancement of the PACP, MACP and LACP programs; members only programs that will
 offer both technical and marketing position support; sponsorships of valuable industry programs and much

 So, become active in NASSCO, take a leadership role, give back to the industry and reap the personal bene-
 fits that result.

 Enjoy the rest of your summer. I look forward to seeing you all at our semi-annual meeting in October at
 WEFTEC in Washington DC.

Dear NASSCO Times Readers:

                We have a new look! I still have the beard and Heather still looks like Heather but the
                NASSCO look is different. We have redesigned the NASSCO website so it is easier to find
                what you need. If you have not recently seen our website take a moment now to find us at
       One of the exciting features is the membership directory that allows a
                search by product, territory or keyword (territory search available soon). Many of you have
                sent us the information needed to enable us to improve the directory by showing a list of
                products or services you have and by including the geographic areas you serve. Many of you
                have not responded to our request for this information. If you want your products or services
                fully cross-referenced in the directory, it is not too late to get the information to us. The new
                directory format is being developed now and will be available in the very near future.

We have completed most of our plans for WEFTEC in the first week of November in Washington, D.C.. We
will have our semi-annual meeting on Monday, October 31st at 5:30 pm followed by our Ice Breaker Reception
at 6:30 pm for members and potentially new members.
                                                                                           “...the NASSCO

well under way. We have a newly designed way to demonstrate pipe defects and the
options for rehabilitating them while maintaining the “No Selling” professional envi-
ronment you have come to expect from the Rehab Zone. Ed Kampbell, Chairman of
the Rehab Zone will be contacting all past sponsors and new ones to help us make this the best Rehab Zone
ever. We think this Rehab Zone will be so spectacular that everyone will want to be part of it! (see page 9 for
more information)

I hope to see you all at the upcoming shows and meetings. Enjoy the rest of your summer!

                    Rehabilitation of the Sims Bayou Sewer
                                            George McAlpine and Mark Boyer

In June 2004 the city of Houston awarded two contracts for Package 2 and Package 3 for the Sims Bayou Large Diame-
ter Pipe Rehabilitation Project to Boyer, Inc. of Houston, Texas to install the Danby GIPL (ASTM F 1698). Package 2
involves the rehabilitation of approximately 1500 feet of 72” ID and 3500 feet of 78” ID CIPCP and Package 3 covers
5000 feet of 78” ID CIPCP. Hydrogen sulfide induced corrosion varied from moderate to severe producing areas of
exposed rebar reinforcement with levels of rebar steel cross-sectional area loss from none to severe. However, there
were no collapsed areas and very few areas with longitudinal cracks.

GIPL Installation
The three major work processes involved in the installation of the GIPL are cleaning of the pipe wall, spiral winding of
the PVC lining into a tube with an inner diameter about 4” less than that of the host pipe and grouting the annular space
between the PVC liner and the host pipe. In any given section of pipe the work proceeds in the order as listed, i.e.,
cleaning, lining, grouting. However, on a large (length) project such as this, three work crews can execute these three
tasks simultaneously. Of course, there are several other subsidiary tasks such as lateral and side sewer reconnection and
building of bulkheads at manholes and intermediate bulkheads that serve as grout dams.
 Cleaning. The three principal stages of cleaning of large diameter pipes are 1) removing loose debris from the invert, 2)
removing loosely bonded deposits from the pipe wall and 3) removing more tightly bonded deposits and hydrogen sul-
fide induced concrete corrosion products (principally from the upper regions of the pipe wall). Smaller volumes of in-
vert debris can be removed by high-pressure water flushing to a manhole followed by either vacuum or mechanical re-
moval from the pipe. The level of debris in the invert of the Sims pipes required dragging a specially designed bucket,
shaped to match the pipe invert, through the pipe to effect mechanical removal of the bulk of debris. The second stage
cleaning was accomplished by the innovative use of large construction equipment pneumatic tires as huge squeegees/
swabs (see Figure 1). Hydroblasting (10,000 psi) final stage cleaning removed all remaining material leaving only com-
petent concrete. In the upper reaches of the pipe walls, where the H2S corrosion was prominent, the surface is very
rough with well-anchored large aggregate exposed (See Figure 2).

                                       Figure 1. Cleaning bucket and tire swabs.

As corrosion levels dictate, steel welded wire mesh was placed to cover areas of corroded steel reinforcement (rebar).
See Figure 2.

After a relatively slow start, AAA Flexible Pipe
are now installing up to six sub 30 foot long repair
sleeve in a day. "This is a record for Easy Liner
installers in the USA", says Leke Osi.

The job is now in its final stages and the re-
cordings of the repairs are trickling in to Mr. Frank
Varicalli office of Anderson, Eckstein, & Westrick
the Engineering Consultants. Mr. Varicalli states
that he is pleased with the quality of repair work
by AAA Flexible Pipe Cleaning Corp. Mr Vari-
calli said he was a bit worried at the start, but was
impressed with the attitude showed by both AAA
Flexible and Easy Liner field training staff, to-
wards dealing with the problems.

 Mr. Frank Ziegenruecker Vice President of AAA
Flexible Pipe Corporation states that he is very
happy with both the products, training and con-
tinuing support of Easy Liner technical staff. He
says "they have been of great assistance on this job
and have given us the added confidence and am-
munition to go after the multi million dollar Short
Liner contracts, with a formidable chance of win-

                                Rehabilitation of the Sims Bayou Sewer
                                                           (continued from page 10)
PVC Liner Installation. The PVC liner was delivered to the job site in 300 ft coils (ID = 64 in, OD = 90 in). The 12 in
wide profiled liner has “T” shaped ribs on one side (overall height of 1.0 in) and a smooth surface on the other (flow sur-
face). The liner was taken into the pipe’s interior by simply pulling the PVC liner from the inside of the bound (at the
OD) coil down through the manhole. As the spiral winding proceeded past laterals or side sewers, holes were cut into
the liner and PVC pipes/tubes were inserted into the lateral and through the PVC liner. The new inserted PVC tube/pipe
was sealed both in the existing lateral/side sewer and at the PVC liner surface before the annulus grouting reached it to
prevent grout filling the lateral/side sewer and or leaking into the interior of the PVC liner.

                                    Figure 3. Installed GIPL and grout dam/bulkhead.
         In this project, the contractor chose to line continuously through all manholes and provide access by cutting a
suitable hole through the top of the liner. Of course, suitable bulkheads were installed around all such cuts in the liner to
prevent annulus grout from entering the liner’s interior. Sims project specifications required 18 new manholes with Am-
eron T-Lock™ lined 6-ft diameter concrete risers. The (PVC) T-Lock™ riser liners were welded to the Danby PVC
liner to produce an entirely PVC sewer interior surface that will be impervious to the hydrogen sulfide corrosive effects.

Annulus Grouting. All structural rehabilitation of the host rigid pipe by GIPL is due to the effects of the high strength
annulus grout, in conjunction with added steel if used. The PVC liner provides a smooth flow surface, a chemically pro-
tective containment, and formwork for the annulus grout. Its contribution to structural improvement is not significant.
Thus the composition and placement of the annulus grout is very important to the proper installation of any GIPL.

Repeatability of grout mixes is greatly influenced by consistent addition of the proper amount of mix water and chemical
admixtures and consistent mechanical mixing. Automation removes human errors and improves repeatability. The mo-
bile grout plant employed on this project had programmable logic controlled metering of the mix water and chemical
admixtures as well as the mixing time of the colloidal mixer.      (continued on page 18)

The EPA officially withdrew their proposed ban of Acrylamide grouts on December 2,
2002. The ICGA (International Chemical Grouting Association) was formed to focus on
projects that can help the grouting community increase awareness on the benefits of chemi-
cal grouting and remove some of the incorrect myths that have been generated over the past
10 years.

In reviewing different methods to accomplish our goals, we have chosen to produce a web-
site to provide accurate information on chemical grouting as our first project. A website
was chosen because it would provide a connection to the broadest audience via the internet,
and be the least costly to create and maintain. Our goal is to begin work on the ICGA web-
site this summer and have it ready by the 4th quarter of 2005.

The scope of the website will be based on the revenue that can be generated through the
collection of membership dues for the ICGA. The ICGA annual dues are structured to bal-
ance the cost and benefits between the NASSCO members and associate members. We are
also offering a category for NASSCO members who are not direct beneficiaries when rais-
ing the awareness of chemical grout, but who have been long time supporters of this indus-
try and wish to continue their involvement.

Most likely you have already paid your 2005 NASSCO dues. Next year you will have the
option of paying ICGA dues on the same form as your NASSCO payment. Since we were
unable to list this option earlier this year, we are encouraging all interested NASSCO mem-
bers to join ICGA and pay their 2005 dues to fund the website project and begin building a
resource base for the ICGA.

Please contact NASSCO to join ICGA, or go to the ICGA page on the NASSCO
website, to download a form to join ICGA. Thank you for your support.
