KWIK SLAB APPLICATIONS
MR. ALFRED A YEE, structural engineer and inventor of the KWIK SLAB system.
● Inventor, NMB Splice Sleeve a mechanical coupler for precast construction.
● Member, National Academy of Engineering
● Titan, Precast/Prestressed Concrete Institute
The KWIK SLAB with KWIK JOINT couplers rapidly interlocks precast concrete slabs for two-way rebar continuity throughout entire pavement
slab.
(Covered by U.S. Patent No. 7,134,805)
► STRUCTURALLY SUPERIOR.
► FULL INTEGRITY & CONTINUITY AT BOTH DIRECTIONS.
► FLEXIBLE SIZE AND SHAPE DESIGNS.
Laboratory test results show FULL CONTINUITY action in shear and moment
between individual KWIK SLABS.
JOINT BETWEEN KWIK SLAB
KWIK JOINT pull-out test demonstrated full strength of connected reinforcing bars for
reliable MONOLITHIC ACTION.
► Cast and cured offsite.
► Transported to jobsite as needed.
► Saves weeks of onsite construction time.

● Ready-mix grout is pumped through holes in the slab and distributed through channels cast on the underside of the KWIK SLAB.
Grout channels on the underside of the KWIK SLAB create continuity in the grout bed and help develop full
bearing of the slab on the subgrade.
