PARSON
HYDRO GROUT

Quickly stop infiltration through cracks in manhole walls

DESCRIPTION:
PARSON HYDRO GROUT is a tough, low viscosity, hydrophobic polyurethane grout, when mixed with predetermined amounts for PARSON GROUT ACCELERATOR, will exhibit controlled reaction times from 30 seconds to 3 minutes. PARSON HYDRO GROUT can be used to stop medium to high volume active leaks through hairline cracks in Manholes, Pump Stations, Water and Wastewater tanks, Concrete pipes and other Concrete and Masonry Structures. It may also be used as a soil stabilizer.

ADVANTAGES:

Cures to a closed-cell foam
Chemically resistant
Fills voids and holes
Low viscosity allows good
penetration into small cracks
Non Hazardous
Environmentally Friendly

MIXING: Perform "cup tests" to determine reaction times by accurately measuring small amounts of PARSON HYDRO GROUT and PARSON GROUT ACCELERATOR. Begin with approximately 1 1/4% Accelerator to Grout ratio, which should yield a reaction time of approximately 45 seconds. Pour both products into a small plastic cup and stir until thoroughly mixed. Record the amount of time until the product reacts. If reaction time needs to be adjusted, add more PARSON GROUT ACCELERATOR to shorten, or less to lengthen the reaction time. When the desired reaction has been achieved, both products may be mixed in larger volumes using a jiffy mixer. 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 holes approximately half 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 HYDRO GROUT using recommended pumping equipment. Care should be taken not to over inject. When grout reaction is achieved, move to the next application port.

PRECAUTIONS: PARSON HYDRO GROUT is moisture sensitive and should not be exposed to ambient conditions until ready to use.

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: Store in original container at room temperature. Shelf life is 1 year in original unopened containers.

PACKAGING: PARSON HYDRO GROUT is available in 5 gallon plastic jugs and 55 gallon metal drums. PARSON GROUT ACCELERATOR is available in 1 pint metal cans.
