PRODUCT DESCRIPTION

Tasir® Centrifugal Cast Pipe Repair Mortar is a high-performance repair mortar that provides a structural repair by creating a new, continuous, cementitious pipe within an existing, properly designed and installed culvert. This single component, fiber-reinforced hydraulic repair material is capable of making repairs without disturbing the pipe. Tasir® Centrifugal Cast Pipe Repair Mortar provides sealing, rehabilitation and corrosion protection of existing underground metal and concrete pipes and is a quick and economical pipe repair solution. For added protection,Tasir® Centrifugal Cast Pipe Repair Mortar with Microban® Technology is infused with an antimicrobial agent that inhibits deterioration caused by MIC (microbiologically induced corrosion).

ADVANTAGES

● Large volume applications

● Centrifugally cast in place

● Low chloride ion permeability

● Versatile ¼ inch (6 mm) to 1 inch (25 mm) single pass applications

● Fiber reinforced for crack resistance and strength

● When infused with Microban® Technology the useful life of mortar is extended by inhibiting deterioration caused by MIC (microbiologically induced corrosion)


USES

● Trenchless repair of underground pipes

● Pipe rehabilitation, repair and protection

● New pipe corrosion protection

● Invert repairs


PACKAGING AND YIELD

Tasir®  Centrifugal Cast Pipe Repair Mortar is packaged in 50 lb. (22.7 kg) heavy-duty polyethylene lined bags yielding approximately 0.45 cubic feet (12.7 liters) of hardened material at maximum water content. Bulk bags are available upon request.


SHELF LIFE

One year in original unopened packaging when stored in dry conditions; high relative humidity will reduce shelf life.

PLACEMENT GUIDELINES

1. PREPARATION: Prepare all interior pipe surfaces with a high pressure water-blast to remove all laitance, loose material and oxidation, divert water flow and then flush all material from pipe. Rusted portions of corrugated steel pipe should be mitigated or repaired as necessary. Plug active leaks and fill voids; use either Tasir®  Centrifugal Cast Pipe Repair Mortar, Tasir® Structural Concrete or Tasir® Structural Concrete V/O for invert/base replacement. Metal surfaces should be blasted clean using high-pressure water blast equipment.

2. MIXING: Prewet mixer and empty excess water. Slick pump lines with an appropriate material to facilitate pumping. Pump out all material used to slick lines before spin casting product. Start by adding approximately 80% of the total water content (as stated on packaging) to the mixer, add product and mix for 2 minutes after last bag is added. Stop mixer, check consistency and add additional water if necessary. A wetter consistency will result in thinner application thicknesses. Pump and apply immediately after mixing. Working time is approximately 30 minutes.

3. EQUIPMENT: Standard mortar mixers, compressors and pumps are required. A spin cast applicator is required. Contact Tasir® Products'Engineering and Technical Center at +86-571-87569602 for equipment recommendations and detailed installation instructions.

4. APPLICATION: Position the spin cast applicator within the center of the pipe and commence pumping the mixed mortar to the spin caster. As the mortar begins to be centrifugally cast evenly around the interior, retrieve the spin cast applicator at the best speed for applying the thickness that has been specified. Thickness may be verified at any point. If additional thickness is desired at any location, place the spin cast applicator at that location, once initial placement is set and sufficiently hard, and recommence pumping and centrifugal casting until proper design thickness is achieved. Keep pump lines cool by spraying with cold water when temperatures are 90°F (32°C) or higher. Transfer mixed Tasir®Centri-Cast Pipe Repair Mortar from mixer to pump and immediately start next mix. Apply in suitable thickness of ¼ to 1 inch in single pass. Allow material to set and stiffen before applying subsequent pass.

NOTE: PRIOR TO APPLICATION, READ ALL PRODUCT PACKAGING THOROUGHLY. For more detailed placement procedures, refer Tasir® installation guidelines or call Tasir® Products'Engineering and Technical Center at +86-571-87569602.


CONSIDERATIONS

● Never exceed the maximum water content as stated on the package or mix to a consistency which will cause segregation.

● Temperature of surfaces must be between 45°F and 90°F (7°C and 32°C) at time of placement. For cold and hot weather placement, call Tasir® Products'Engineering and Technical Service Center at 1-800-243-2206.

● Repair mortar shall be protected from freezing until it reaches 1,000 psi (6.9 MPa).

● Product sets slower in cooler temperatures and faster in hotter temperatures.


CAUTION

Contains cementitious material and crystalline silica. International Agency for Research on Cancer has determined that there is sufficient evidence for the carcinogenicity of inhaled crystalline silica to humans. Take appropriate measures to avoid breathing dust. Avoid contact with eyes and contact with skin. In case of contact with eyes, immediately flush with plenty of water for at least 15 minutes. Immediately call a physician. Wash skin thoroughly after handling. Keep product out of reach of children. PRIOR TO USE, REFER TO SAFETY DATA SHEET.
