structures. Strong-Seal is the cost-effective
solution for stopping inflow and infiltration
(I&I), restoring structural integrity, and providing
corrosion protection.
When spray-applied to a minimum of ½-inch
thickness, the Strong-Seal fiber-reinforced monolithic
liners have strengths exceeding that of the original
structure. Made with Portland cement, Strong-Seal
MS-2A is the most cost-effective solution. The MS-2C
product provides high early strengths and added
corrosion protection in mild sulfide environments.
Strong-Seal High Performance Mix is a purefused calcium aluminate mortar that protects
against microbiologically induced corrosion in
harsh sulfide conditions.

As a provider of infrastructure-related safety
equipment and solutions, Arcosa Shoring Products
strives to create long-term value for its customers
and stakeholders by promoting a culture that
values environmental, social and governance (ESG)
responsibility. To that end, Arcosa recently produced
a video highlighting its ESG commitment.
" Clearly the trench shoring industry's number-one priority is safety, " said Joe Zylman, president of Arcosa Shoring Products and NAXSA Board
Member. " However, underground construction

personnel are not the only beneficiaries of all that
we do collectively.
" The environment benefits every time a contractor digs a trench to install shoring, rather than
sloping, " he added. " Yes, trench shoring saves lives,
but it also does so much more. "

Arcosa Shoring Products, " is located on YouTube at

PPI

According to the Plastics
Pipe Institute, Inc. (PPI), the
latest AWWA C901 standard
provides specifiers and
end-users with the best
grade of high-density
polyethylene (HDPE) pipe
for water service pipes.
Under this updated standard, HDPE pressure pipes and tubes from ¾ inch
through 3 inches, produced under C901-20 must
be manufactured from PE4710 compound and be
SDR9 (PC 250). It also raises the cell classification
for oxidative resistance to CC3 (for potable water
piping systems), the highest and only acceptable
level of chlorine and chloramine resistance in
potable water systems.
" The seventh and latest edition of this standard
requires the use of CTS or IPS-sized HDPE pipe, and
removes the option for special sizes that allowed for
different SDRs, " stated Camille George Rubeiz, P.E.,
F. ASCE, senior director of engineering for the Municipal and Industrial Division of PPI. Rubeiz, who is
also the co-chair of the HDPE Municipal Advisory
Board, chaired the AWWA C901 Subcommittee
responsible for updating the standard.
" Basically, the changes to the standard eliminate
the use of thin-walled HDPE pressure pipe and tubing for potable water, reclaimed water and also for
wastewater service. It's another way for the HDPE
industry to protect communities from non-compliant products and provide the best solution for the
replacement of dangerous lead service lines.
" Also, for potable water with chlorine or chloramine residuals, " he continued, " C901-20 requires
HDPE pipe with a minimum cell classification of PE
445574(C or E) CC3. CC3 calculations are available
in the updated PPI TN-49 (2020) document and in
HDPEapp.com. "
Rubeiz said that there is also related information
in the recently released AWWA M55 (2020) manual.
