Poured Wall Reinforcements – Advanced Carbon Fiber Technology
LAYING OUT JOB/PREPARING THE WALL
Step
1: Measure the length of foundation cracks and divide the
length into 2 ft. segments. Make sure that no obstructions
interfere with the planned stitch locations and that there
is no more than 24” between segments.
Step 2: Mark the stitch locations on the wall, holding staple
over the wall location (perpendicular to the concrete crack)
and trace the area.
Step 3: Prepare the crack surface as usual for injection,
wire brush 2” along total length of the crack.
Step 4: Prepare the wall surface within the traced area, remove
paint, bumps and irregularities. It is best to use a dustless
grinder to ensure staples lay flat to the wall. The surface
must be as smooth as possible and free of dust for adhesion.
APPLYING REINFORCING STITCHES:
Step
1: Surface seal only over traced areas on the wall (where
stitches are to be placed) by working a small amount of Emecole
301, 901 or 455 fast surface seal into the crack either through
a mixer or by trowel. (No surface seal outside of crack.)
Step
2: Apply ports and surface seal to remainder of concrete crack
outside of traced areas as usual.
Step
3: Prepare staple by removing Clean Peel fabric and discarding.
Place the staple over the roll of plastic Seal Sheet and cut
Seal Sheet to length.
Step 4: With the Seal Sheet under the staple, apply an even
stream of Emecole 4121 epoxy in a zigzag pattern on the staple.
Put as much epoxy adhesive as needed to make a smooth, flat
layer.
Step 5: Under the large trowel, spread the epoxy to achieve
an even and flat coating.
Step 6: Pick up the staple by holding the edges of the Seal
Sheet and press into position, epoxy side on the wall. Begin
at the lowest traced area over the crack and work up towards
the top until all staples are placed.
Step
7: Leaving the Seal Sheet in place, trowel the epoxy out evenly
over the staple. Ensure epoxy penetrates the grid and covers
the staple completely. Use trowel to push epoxy to fill gaps
and unfilled spaces. Grid must be completely covered.
Tip: Some areas of the staple may separate away from the resin
because of the existing deflections in the wall. These areas
can be anchored to the wall with a 1” concrete nail
and a washer. All nails must go in the gaps between weaves.
Nails are only needed when separation occurs.
Step
8: Check to insure that the surface seal is as hard as a finger
nail before completing the crack injection process.
