2.6 Grouting Troubleshooting Guide
I. Recommended Equipment:
1. A large piston or garden sprayer filled with water (4 gallon or larger)
5. Rubber Stoppers
and/or high pressure water hose with sprayer attachment. 6. Electric Drill with masonry bits
2. Compressed Air Source 7. Flashlight
3. Steel Rod – 1/4 to 3/8 inch (6 to 10mm) in diameter 8. Sealing Disks
4. Hammer 9. Dry Pack Mortar
The above equipment should be on-hand and available during grouting.
IF SEALING MORTAR
IS NOT SET:
1. Lift the top panel off
and clean out any sealing
mortar inside the
couplers and any loose
mortar using high
pressure water.
2. Once clean, reinstall
the panel and confirm
a clear passage by
shining a light into the
inlet and outlet tubes.
Blow out the tubes
with compressed air.
IF THE SEALING
MORTAR IS HARDENED:
1. Insert a steel rod into
the tube, and hammer
it to strike out the
sealing mortar that is
blocking the tube.
2. Blow out the tubes
with compressed air
and confirm a clear
passage from the inlet
to outlet tubes.
A vacuum may also
be needed to remove
debris from the interior
of the coupler.
3. Make sure
recommended volume
of grout can be
placed into coupler.
If not, contact the
Structural Engineer.
1. Check and mark the
position of the inlet/
outlet tubes according
to the drawings.
2. Chip down the
marked positions to
the embedded tubes.
Remove all debris.
3. Blow out the tubes
with compressed air
and confirm a clear
passage from the inlet
to outlet tubes.
To aid in confirming a
clear passage, shine a
light into the inlet and
outlet tubes.
1. Inlet/outlet tubes
do not reach the
surface.
2. Due to omis-
sions of sealing
disc, inlet tube is
blocked with
sealing mortar
from the joint.
TROUBLE SOLUTION TROUBLE SOLUTION
5. Panel won’t
seat to proper
embedment
length.
4. Leakage during
pumping of
HY10L grout
from the
joint due to
incomplete
sealing.
3. Inlet and/or
outlet tube is
blocked with
concrete debris
etc. or by inlet/
outlet plugs
that have become
wedged inside
the tube.
FOR DEBRIS ETC.:
1. Insert a steel rod into the
tubes and hammer it to
clear the tube.
2. Blow out the tubes with
compressed air and
confirm a clear passage
from the inlet and outlet
tubes. To aid in confirming
a clear passage, shine a
light into the inlet and
outlet tubes.
INLET/OUTLET PLUGS:
1. Use a hooked rod or wire to
scrape plugs out of the tubes.
2. Blow out the tubes with
compressed air and confirm
a clear passage from the
inlet to outlet tubes.
1. Seal the joint with rags,
polyurethane, etc.
2. Start regrouting.
1. Dowels are too long –
cut to proper length.
2. Debris in coupler –
remove all debris,
hardened cement, or
water in bottom of
coupler. Blow out with
compressed air and
confirm that coupler
is clean.
