SPEED and STRENGTH SPEED and STRENGTH

When speed of construction and strength of slab are your concerns,

the KWIK SLAB system is your fast and strong answer.

(Covered by U.S. Patent No. 7,134,805)

The KWIK SLAB system allows roadways to be installed in a matter of days versus

weeks.

• RAPID INSTALLATION

• MONOLITHIC ACTION

• TWO-WAY REBAR CONTINUITY

• PRECAST CONCRETE SLABS

• FLEXIBLE SLAB DESIGNS

► NEW CONSTRUCTION

► EXTENSION OR REPAIR OF:

• ROADWAYS & HIGHWAYS

• BUS STOPS

• BRIDGE DECKS

• PARKING LOTS

• AIRFIELDS

• DOCKS

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.

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.

● 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.

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.
