* The floor must be properly aged to American Concrete Institute specifications. The floor does not require reinforcement,
but a minimum of 4” x 4” x 10/10 wire mesh is recommended.
** Larger 4’ x 4’ base pads (available from Mohawk) required for floors with a thickness range less than 6”, but greater or
equal to 4 1/2”.
The floor should be test drilled to verify minimum floor thickness and to confirm building drawings. A core sample should be
obtained and tested to verify minimum floor compressive strength. When investigating floor properties, consult building
drawings to verify proper floor reinforcement.
All 2-post lifts require a continuous single slab. Spanning expansion seams or positioning posts on separate slabs is not
acceptable.
--- ALL MOHAWK LIFTS MUST BE INSTALLED ON CONCRETE ONLY ---
DO NOT install any Mohawk lift on any surface other than concrete, conforming to the minimum compressive strength,
aging, reinforcement, and thickness stated in the table above.
DO NOT install any Mohawk lift on expansion seams or on cracked or defective concrete. All ¾ inch diameter anchors must
be a minimum of 6 inches away from any expansion seams, control joints or other inconsistencies in the concrete. All 1 inch
diameter anchors must be a minimum of 7 ½ inches away from any expansion seams, control joints or other inconsistencies
in the concrete. Refer to anchor manufacturer specifications for specific information concerning edge distances and bolt to
bolt distance requirements.
NEVER, NEVER install a Mohawk lift on hand mixed concrete.
DO NOT install any Mohawk lift on a secondary floor level or on any ground floor with a basement beneath without written
authorization from the building architect and prior consultation and approval from Mohawk Resources Ltd.
If the floor does not meet these minimum pre-existing floor requirements, it is suggested to construct a slab as outlined in
New Slab Recommendations. If the location of the lift is in a seismic zone, additional provisions will need to be considered,
and it is recommended to consult a building architect or engineer.
