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)
KWIK SLAB AND KWIK JOINT COUPLER
► 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.
KWIK SLAB MANUFACTURING
► Cast and cured offsite. ► Transported to jobsite as needed. ► Saves weeks of onsite construction time.
KWIK JOINT couplers are cast into the KWIK SLABS at the precast yard.
KWIK SLAB INSTALLATION
● Use cold planing equipment to excavate accurately and quickly. Subgrade is graded and compacted.
● KWIK SLABS are lifted into place, interlocked and leveled (with plastic shims, etc.).

● 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. GROUT HOLES GROUT CHANNELS
● KWIK JOINT couplers and keyways are filled with high-strength grout.
● After installation, any surface irregularities or finishing of KWIK SLABS can be addressed with concrete coatings, asphalt overlays, grinding, etc. DURUS ® #30 GREY cementitious coating applied to create desired finish on KWIK SLAB.

● Completed KWIK SLAB SYSTEM (with thin DURUS ® cementitious coating) installed in existing asphalt pavement.
The KWIK SLAB system is designed to support heavy loads.
KWIK SLAB system in service since March 2005.
Almost 2 years later, no visible signs of wear or deterioration.
