Step 2Tools: Safety Equipment – Gloves, Safety Glasses, Dust Masks, Knee Pads, Caution Tape or Cones Minimum Basic Tools – Shovel, Tape Measure, Gardening Shears, 2lb. Hammer, Long Rock Bar, Short Wrecking Bar,  5  Gallon   Buckets, Tarp, Mason’s Chisel, Grout Tubes 		Step 3
Step 3Determine settled sidewalk area
and draw sketch to help determine, length, width, thickness and
weight.
Step 4
Step 4Chart shows weight per square foot relative to slab thickness.

NOTE:    SlabJack’s are placed 4 to 6 feet apart where the sidewalk is sinking.  A small hole adjacent to and under the sidewalk has to be excavated to allow for the SlabJack and a small amount of concrete to be poured.  After all SlabJack’s have been installed the sidewalk is ready to be lifted.
Step 5
Step 5Chart provides product description, lift capacity, load capacity, # of threads per inch, weight, required square feet of poured in place QUIKRETE and amount of QUIKRETE per placement in pounds. 		Step 6
Step 6Surface hole dimensions adjacent to sidewalk.
Step 7
Step 7Excavation dimensions under the
sidewalk.


Step 8
Step 8Surface view to show center line placement of PVC 1-1/2” schedule 40 x 2’-0 long to create a void to allow for SlabJack.  (Purchase from local hardware store.  Reused for each SlabJack placement.)
 Step 9
Step 9Image shows minimum distance required to allow for SlabJack placement.  Using a 2 lb. hammer and PVC tube, drive PVC tube into soil.  (Reuse PVC tube for each SlabJack placement.)
Step 10
Step 10Place SlabJack into void created by PVC tube and push vertical.

Step 11
Step 11Shows placement of SlabJack under sidewalk. 		Step 12
Step 12Hold hex nut / rebar to turn handle where SlabJack fits snug under sidewalk.
Step 13
Step 13Another view showing SlabJack
fit snug from the bottom of the
sidewalk to the bottom of the void
created by PVC tube.

Step 14
Step 14The LIGHT BLUE color shows the back fill soil to be placed to hold SlabJack and to minimize the amount of concrete that has to be poured. 		Step 15
Step 15The LIGHT BLUE color shows the back fill soil and dimensions of the back fill soil to be placed.
Step 16
Step 16A 5 gallon  bucket, a gallon  bucket of water, an 80 pound bag of QUIKRETE and small mixing shovel.  Place 4-5 inches of  QK in 5 gal. bucket equals approximately 20 lbs. QK.
Step 17
Step 17LIFT sidewalk  by turning handle…  LIFT a LITTLE at a time to prevent cracking in sidewalk... snug adjacent SlabJack’s... Continue to desired elevation.            (For heavier lifts… have a person at each SlabJack and turn handle at same time.) 		Step 18
Step 18LIFT sidewalk by turning handle,
snug adjacent SlabJack’s. LIFT a
little at a time to prevent cracking
in sidewalk. Continue to desired
elevation.
Step 19
Step 19The PURPLE color shows the void created after the lift.

Step 20
Step 20The LIGHT BLUE color is back fill
soil to minimize the amount of
flowable grout to fill voids. Also
shows PVC 2” sch 40 tube placed
with 90 degree elbow to fill voids. 		Step 21
Step 21Shows PVC 2” sch 40 tube in place
ready to fill voids from lift. Pack soil
around PVC to support and hold vertical. Pour flowable grout to fill voids. (Purchase from local hardware store.)
Step 22
Step 22Continue to fill voids until adja-
cent PVC tubes indicate flowable
grout is visible. After voids are
filled remove PVC tube and finish
grade soil and sod. 		Step 23
