Table Rock Asphalt
Construction Co., Inc.
is the only area company
to provide river rock
that is
primarily used
for landscaping
and exposed aggregate
concrete. TRAC Inc.
operates two Tug-Boats
and Barges that dredge
the river rock from the
bottom of Lake
Taneycomo. The material
is then off-loaded from
the barges to an onshore
plant that washes, sizes
and sorts the material.
Following this process,
the material is then
stock piled on site for
drive on customers or
loaded into haul trucks
for delivery.
An
exposed-aggregate surface is
obtained by placing concrete and
then removing the outer “skin" of
cement paste to uncover decorative
coarse aggregate (either batched
into the concrete mix or seeded onto
the surface). Because of its
durability and skid resistance, an
exposed-aggregate finish is ideal
for most flatwork.
An exposed-aggregate finish
is also possible on concrete
walls or tilt-up panels.
Vertical applications
include
With an exposed-aggregate
finish, you can achieve
spectacular effects at a
reasonable cost because few
additional materials (other
than the decorative
aggregate) and tools (beyond
basic finishing tools) are
required.
Here are some other notable
advantages of
exposed-aggregate finishes:
The
basic procedures are
simple enough for
experienced finishers to
master easily.
The surface is rugged,
nonskid, and resistant
to heavy traffic and
weather extremes.
Many types and sizes of
decorative aggregate are
available to achieve
unlimited color and
texture variations.
Exposed aggregate is
highly versatile and
contrasts beautifully
with plain concrete or
other decorative
treatments such as
stamping, stenciling,
staining, and integral
coloring.
Little maintenance is
required, other than
sealing and occasional
cleaning.
The barges also
allow TRAC Inc. to provide shoreline stabilizing services for
eroded shore lines
along the banks of the lake. A larger size rock called Rip-Rap
is traditionally used because it provides more stability against
currents then smaller aggregates. The specified aggregate
material is delivered by barge and placed onto the shoreline to
build back up and reinforce the shore against further erosion.
The stabilizing process, however, must be initially permitted
through the Corp. of Engineers by the property owner.
