PARSON PERMA SEAL |
Water Reactive Grout

|
DESCRIPTION:
PARSON PERMA SEAL is a single component,
hydrophobic polyurethane grout.
It contains no TDI or solvents and has excellent elongation and
flexibility properties. Reaction time when mixed 1:1 with water
is approximately 30 seconds. PARSON PERMA SEAL can be used to
stop low to medium volume active leaks through cracks, voids or fractures
in Manholes, Pump Stations, Water and Wastewater tanks, Concrete
Pipes and other Concrete and Masonry Structures. |
ADVANTAGES:
- Chemically Resistant
- Great Adhesion
- Stops active leaks
- Non Hazardous
- Environmentally Friendly
- High Elongation
- Excellent Flexibility
- Easy to use

MIXING: PARSON PERMA SEAL may be used
as a single component grout or mixed with water. At a 1:1 ratio of
grout to water, the reaction time should be approximately 30 seconds
and expansion time should be approximately 6 minutes. Please note
the actual reaction times may vary slightly due to ambient temperature
and humidity.
APPLICATION: Drill several 3/8” holes that are in close
proximity to the leaking area using alternating hole patterns with
one hole on each side of the crack or leak. Drill the holes through
the structure. The distance from the crack should be equal to ½
the depth of the structure. Install one 3/8” drive-in port into
each hole. Follow standard injection practices starting from the bottom
port. Begin injecting PARSON PERMA SEAL using recommended pumping
equipment (see accessory page). Care should be taken not to over inject. When grout rejection
is achieved, move to the next application port. Refer to our Chemical
Grouting Specifications for additional information. |

PRECAUTIONS: PARSON PERMA SEAL is moisture sensitive and should not
be exposed to ambient conditions until ready for use. Completely reseal
container immediately after use. Avoid contact with moisture.
SAFETY: Wear protective eyewear and headgear and cover all exposed
skin. Follow appropriate OSHA requirements and procedures for confined space
entry. Refer to container label for First Aid procedures. See MSDS for specific
instructions.
STORAGE: Shelf life is 5 years in original container stored in dry
environment at 70°F.
PACKAGING: PARSON PERMA SEAL is available in 5 gallon plastic jugs and 10 oz. caulk tubes.
