Surface Preparation of Crack

1. Crack must be visible at all points along where it is to be repaired.
2. Wire brush crack area with the intention of creating a clean surface for surface seal material.


3. Using the palm of the hand, pat the crack area to remove dust.
4. Using barrier cream, grease 1/8" rods (straws).

5. Insert port rods by pinching end and pushing into crack.
6. Port rods should be set, inserted at intervals equal to the thickness of the wall being repaired (generally 8-10" apart).

Mixing & Applying Paste Epoxy Surface Seal

(Paste Epoxy in Margarine Tub)

Mix equal parts of A & B in clean margarine tub. Mix small manageable amounts (2-3 tablespoons of each). Mix rapidly to a uniform color (mixture should be streak free). Apply mixture with trowel over crack and around straw. Paste surface seal will harden/cure in approximately 8 hours.

3. Surface seal is then troweled over crack area and around port.
4. Leave excess of surface seal around port rod.


5. Remove plug from port assembly.
6. Slide port over port rod while surface seal is still plyable.

7. Excess surface seal should be troweled over port flange base.
8. Brush out surface seal with paint brush to eliminate pin holes.

Completion of Surface Seal

We have inserted port rods, applied surface seals over crack, around rods, set in injection ports and brushed surface seal to a smooth pin hole finish.

NOTE: If the outside portion of the crack is above grade, this area must be surface sealed to contain the injection resin.

Surface seal has cured:


Remove all port rods.


Selecting Resin:

For a 1/16" crack, we will be using regular injection resin clear in color, consistancy of motor oil.

Mixing Injection Resin

1. Remove tape from cartridge.
2. Pull Dasher rod up towards neck of cartridge. This will release the aluminum foil barrier in area of removed tape.


3. Depress cartridge slightly in area of removed tape to deform aluminum foil barrier.


4. To mix, push dasher rod to the bottom of the cartridge and begin mixing in a spiral clockwise motion from top to bottom of cartridge. Moving the dasher rod in and out of cartidge is one complete stroke. 20 strokes is suggested to obtain mixing of Injection Resin. On the last stroke, pull dasher rod to top of cartridge.

NOTE: down and up = 1 stroke

5. Remove yellow end cap from bottom of cartridge.
6. Unscrew dasher rod (approx. 3 turns) by gripping the cartridge in area of the mix head (top of cartridge).

Loading Injection Gun

1. Insert nozzle by screwing into cartridge top.
2. Unscrew retainer from gun base.


3. Grease (with barrier cream the inside of retainer and grease threads and threaded base. Insert cartridge intro hand gun retainer.
4. Affix hand gun base to retainer.

Injection

1. Nozzle end may be cut off to acquire a larger opening. Nozzle should not be cut off to a point where it will not fit into the port barrel.
2. Insert nozzle into bottom and begin injection of the resin into the crack.


3. When injection resin appears in the port above the one you were pumping, back gun pressure off by dis-engaging gun crank.
4. Insert port plug into the port which was being pumped.


5. Move to the next port and proceed to pump until injection resin appears in the port above.

NOTE: If any pinholes appear in the surface seal when pumping injection resin, use clay to plug these areas.


6. Continue pumping and plugging until the entire length of crack is filled.

NOTE: Injection pors can be removed (broken off) after 48 hours after curing.
