HydraTech Enhances Internal Joint Seal
The HydraTite internal joint seal, manufactured by HydraTech Engineered Products LLC, has a long and proven history for repairing leaking
joints in man-entry sized piping. When joints in box culverts, tunnels,
conduits or other structures with non-circular or -elliptical profiles need
repair, however, the internal joint seal was seldom considered as a viable
remedy - until now.
Based on the same materials and methods that enable the HydraTite
seal to be used in potable water applications, it can be custom-designed to
adapt to joints in rectangular and irregular-shaped structures. It provides
a water-tight seal on either side of the defective joint by compressing
an extruded EPDM membrane against the host concrete structure with
stainless steel retaining bands.
Compression of the EPDM seal is achieved by expanding the retaining
bands, in combination with anchor plates positioned along the straight
runs of the structure. Wedge anchors provide the necessary pressure for
compressing the rubber seal along the straight horizontal and vertical
runs of the structure. Corners or any angles are contoured to a radius to
provide a rounded transition to the adjacent perpendicular surfaces.
Eliminating the need to hand form corners to the required radius,
HydraTech offers the option of fabricated stainless steel corner forms
or extruded EPDM rubber profiles, when inside 90-degree corners are
involved. For the majority of applications involving water, wastewater or
stormwater conveyance, the EPDM seal is shop vulcanized to accommo-

date the structure's
inside circumference. On applications
involving conduit,
piping or other utility and equipment
interferences, the
EPDM rubber may be
vulcanized or bonded
in the field to enable
installation around HydraTite seal is a viable remedy to leaking joints in square
potable water tunnels
.the obstructions.
Similar to installing a seal in a pipe or elliptical structure, there are
size limitations with HydraTite applications in a rectangular or irregular
shapes. The structure must be large enough for man-entry and provide
adequate clearance to ensure installation is conducted in a safe manner.
HydraTite is a reliable way to repair leaks in pressurized systems and
prevent infiltration to buried infrastructure. It's also a long-term solution, compared to alternative methods using sealants, grouts, mastics and
other fillers that rely heavily on proper surface preparation and bonding,
which can be challenging in buried applications.

Municipal Grouting Video Series Helps
Solve I&I Problems
Avanti International has produced a new learning resource for solving Infiltration and Inflow
(I&I) issues in sanitary and storm water systems.
Fundamentals of Municipal Grouting is a 16-module video series designed as an interactive learning experience for those who need-to-know
and want-to-solve the I&I problems destroying underground systems.
Beginning with the History of Sewers (Lesson 1) through Standard Specifications (Lesson
16), the video series delves into grout chemistry and safety, conveyance technologies and
techniques, and holistically targets all infiltration points of entry: mainline sewers, manholes,
service laterals and connections. Produced in high-definition broadcast quality and comprehensive in content, this video series is unlike any other resource serving the trenchless technology industry.
Access to the program is complementary. Municipal stakeholders and specialty contractors have a self-paced training and education resource to enable both technical and operational personnel at no cost. For engineers requiring PDH credits, a $49 administration fee is
required.
Municipal Grouting is a multi-vendor solution. After years of collaborating on grout
schools, webinars and live field-day demonstrations, experts from Avanti, producer and
full-service provider of high-quality injection grouts; Aries Industries, grout truck manufacturer; and Logiball, remote packer manufacturer, joined forces in the name of education to
produce this video series.
"Video-based training is a natural extension of this education initiative and an important asset to teach the fundamentals of injection grouting to specifying engineers and municipal stakeholders, as well as the management, estimators and technician teams of specialty contracting
organizations," said Daniel Magill, president of Avanti. "Beyond the fundamentals, our handson grout schools will continue to provide personalized instruction throughout the year."
