MANHOLE REPAIR PRODUCTS
Cretex

LSS Internal Manhole Chimney Seal is a mechanical seal installed on the frame and grade ring
sections of sanitary sewer manholes to prevent
frame-chimney inflow. During wet weather, clear
water (inflow) that enters manholes through
deteriorated and broken frame-chimney joints, can burden the collection
system. Each seal is made from a high-grade rubber sleeve and stainless steel
expansion bands, which are easily removed and re-installed for future manhole
adjustments.

AP/M Permaform

permaform.net
AP/M Permaform offers solutions for the trenchless rehabilitation of badly deteriorated wet wells,
lift stations, manholes, pipe and similar underground structures. Permacast, a high-strength,
corrosion-resistant liner, is centrifugally cast at
the best thickness (1/2 to 2 inches) for the condition, depth, traffic loading and
ground water pressure. For added protection, ConShield anti-microbial additive
prevents Thiobacillus bacteria that produce sulfuric acid in sanitary sewer
systems, providing long-term protection against microbiologically induced
corrosion (MIC).

Sauereisen

RestoKrete SubstrateResurfacer F-121 is a highstrength, cementious, substrate repair material
for use in the rehabilitation of concrete or brick
manholes. It is typically applied at ground level by
spin-cast application equipment. F-121 provides an economical repair, where
deterioration is greater than small voids, bug holes and irregularities, and as
a water-resistant barrier against inflow and infiltration. In the most corrosive
environments, a topcoat of SewerGard epoxy may be specified for additional
chemical resistance.

LMK Technologies

lmktechnologies.com
LMK's CIPMH (cured-in-place manhole) is a unique, onepiece, resin-saturated liner designed to reduce I&I and
renew structural defects in a variety of manhole configurations and sizes. This one-size-fits-most, reinforced and
stretchable CIP liner is engineered to resist traffic loading
and freeze-thaw cycles, while being corrosion-resistant.
Available for chimney or full-depth manhole rehab, the
ASTM F3033-compliant, vacuum-impregnated liner is
pressed against the existing manhole by a pressurized bladder until thermoset
resins have cured ambiently (about wo hours).

The Strong Company

strongseal.com
The Strong-Seal System offers a complete
family of cost-effective engineered products,
specifically designed to rehabilitate municipal concrete and masonry structures. The

system is intended to stop inflow and infiltration, restore structural integrity and
protect against corrosion. By providing a total system of engineered products,
specialized equipment, and complete customer service, Strong-Seal remains the
technology leader in manhole rehabilitation.

Avanti

avantigrout.com
Infiltration enters into manholes daily, causing
treatment plant overloads, or worse. Manhole
rehabilitation with Avanti's injection grouts is
necessary for the safety and longevity of underground infrastructure. To eliminate infiltration,
there are five grouting techniques: Curtain Grouting, Vertical Crack Injection,
Horizontal Joint Injection, Probe Grouting and Oakum Soakum. Each technique
enables you to stop several leaks at once to extend manhole life.

Hobas Pipe USA

hobaspipe.com
Hobas Pipe USA produces T-Base manhole systems and
other fittings, including elbows, reducers and wyes, to help
complete its product line. Fittings are manufactured of the
same high-quality material as the inherently corrosion-resistant CCFRPM pipe, produced by Hobas from 18 to 126 inches.
Leak-free, push-together joints reduce installation time and
costs. Key applications are sanitary sewers, potable water and
corrosive environments.

Parson Environmental

SEAL-TITE is an easy-to-use, budget-friendly, inhouse way to stop active leaks up to 50 gpm. This
moisture-insensitive, two-component, fast-reacting
hydrophobic polyurethane grout for manholes,
pump stations and other wastewater structures,
cures to a dense, rigid mass in approximately 30
seconds. It's packaged in a dual cartridge with a static mixer, and is injected at
or near the source of the leak using a manual, dual-component caulk gun. The
product contains no solvents, CFCs or HFCs.

Sprayroq

Sprayroq's SprayWall Polyurethane Protective Lining
System was specified for the structural rehabilitation of
lift station #215, as part of a sewer replacement project
for the city of Orlando, FL The lift station measured 4
feet square by 19 feet deep and was severely deteriorated form years of hydrogen sulfide gas exposure. The
project's contractor, Engineered Spray Solutions LLC,
successfully spray-applied 250 mils. of the product, as seen in the before and
after photos.

Sealing Systems

ssisealingsystems.com
Flex-Seal Utility Sealant is a state-of-the-art, plural component aromatic urethane with an incredible 800-percent elongation and tensile strength of 3200psi.
It is designed to prevent inflow/infiltration and provide corrosion protection at
