POST TENSION CONCRETE 

DO NOT CUT OR DRILL THROUGH A POST TENSION CABLE

. 

Do not disturb, bolt up, or apply load to adhesive anchors prior to the full cure of the adhesive.

Metal anchors and fasteners will corrode and may lose load-carrying capacity when installed in corrosive        
environments or exposed to corrosive materials. There are many environments and materials which may cause 
corrosion including ocean salt air, fire-retardants, fumes, fertilizers, preservative-treated wood, dissimilar     
metals, and other corrosive elements.

Finished Diameters for Rotary and Rotary Hammer Carbide Tipped Concrete Drills per ANSI B212.15

(Locate any post tension cables before you drill)  

Detailed Installation Instruction for Expansion Anchors. 

CAUTION: Anchors must be at least 6” from the edge of the slab or any seam.

1.  Measure Lift Placement. 

(see figure 

?) (Recommended use columns as template before drilling and  

mark holes.)

2. Keep the drill in a perpendicular line while drilling.

Let the drill do the work. Do not apply excessive pressure. Lift the drill up and down occasionally to remove  

residue to reduce binding.

3. Drill the hole to depth equal to the length of anchor. Note: Drilling thru concrete (recommended) will allow 
the anchor to be driven thru the bottom of foundation if the threads are damaged or if the lift will need to be 
relocated. 

(Example A.1)

4.For better holding power blow dust from the hole.  

(Example A.2)

6. Repeat Steps 4 thru 5 ( Qty x 10 )

.

7. Move column into place carefully.

8. Place flat washer and hex nut over threaded end of 3/4” x 5 1/2” wedge anchor, leaving approximately 1/16 
inch of thread exposed carefully tap anchor 

(use a hammer Example A.3)

. Do not damage threads. Tap anchor 

into the concrete until nut and flat washer are against base plate. Tighten the nut, two or three turns on         
average concrete (28-day cure). Check each anchor bolt with torque wrench set to 100 foot pounds torque.  

(Example A.4)

   8.1 Using the horseshoe shims provided, shim each column base as required until each column is plumb. If one 
column has to be elevated to match the plane of the other column, add shim plates. Torque anchors to 100 ft-lbs. 
Shim thickness MUST NOT exceed ½” when using the 5 ½” long anchors provided with the lift. Adjust the 
column extensions plumb.

   8.2 Mechanical Anchors:  Expansion anchors that have been set to the required installation torque in concrete 
will experience a reduction in pre-tension (due to torque) within several hours Re-torque the anchor to the    
initial installation torque is not recommended, or necessary.

   8.3 For mechanical anchors that require a specific installation torque: Failure to apply the recommended     
installation torque can result in excessive displacement of the anchor under load or premature failure of the 
anchor. These anchors will lose pre-tension after setting due to pre-load relaxation.

8.4

 If anchors do not tighten to 100 ft-lbs. installation torque, replace the concrete under each column 

base with a 4’ x 4’ x 6” thick (Recommended 4,000 PSI) 3000psi minimum concrete pad keyed under and 
flush with the top of existing floor. Allow concrete to cure before installing lifts and anchors (typically 28 
days).
