Cast Stone and Precast Concrete products.
Description: Cast Stone
(click to enlarge)
| Cast stone resembles expensive cut limestone at 25% of the cost. |
| It is more uniform in color and texture than other cast products. |
| Made from limestone sand, white cement and integrated pigment. |
| Dry packed into molds under pressure.
|
Description: Precast Concrete

| Precast concrete can be made to resemble many natural products. |
| Easier to manufacture and install, not as aesthetically pleasing as Cast
Stone . |
| Made from sand or aggregates, cement, and integrated pigment. |
| Wet poured or hand applied into molds.
|
Description: GRG (glassfiber reinforced gypsum)
| GRG can be made to resemble many natural products. |
| Recommended for indoor use only (unless modified). |
| Made from gypsum, sand or aggregates, polymers, and integrated pigment. |
| Wet poured, sprayed or hand applied into molds. |
The difference between cast stone and precast
concrete is easily seen, and even the novice can appreciate the high quality
limestone like finish on a cast stone product.

A short lesson on our concrete products.
Cast Stone
Used by man since the Egyptian pyramids were constructed, is hand
packed into molds under tremendous pressure, just as in nature when limestone is
made from the extreme pressure on sand, lime and slurry over thousands of years.
This technique of compacting sand, crushed limestone and colored pigment with a
small amount of water ensures a product which closely resembles limestone.
Uniform in color and texture because very little water is used in it's
production, precast is used where limestone or sandstone is desired but is
cost prohibitive. The surface of cast stone shows the aggregate naturally at its
surface, simulating limestone or sandstone.
Resistant to cracking or crazing, it has additives added in the mixing
stage, which help to tightly compact and bond the aggregates to the cement, to
produce a material strength of at least 6500lbs P.S.I.
It is hard, even for the expert, to distinguish from most real limestone
products and has the same characteristics as limestone, just as it comes out of
the mold, with no further treatment.
Precast concrete
Precast concrete manufacturers also
try to simulate limestone or sandstone by pouring a mix of wet concrete into
molds and when cured are then washed with a mixture of muriatic acid and water,
to remove the fine cured cement particles at the surface of the product, and
hopefully expose the aggregates to give the product the highly desired limestone
"look".
This technique is not always successful and where the concrete is denser
or has some mold oil left on the surface the acid cannot do the job, giving the
product a irregular or patchy look. The acid used, also damages the integrity of
the concrete.
The color of concrete is also hard to control because of the large
amounts of water used in the concrete mix. Colored pigment and it's relationship
with cement is affected by the amount of time it is in contact with water and
also the speed in which water is removed from the curing concrete, product made
in early morning retains water for a longer period of time than product poured
later in the day when temperatures are higher, some manufacturers don't measure
precisely the amount of water added to each mix, hence the irregular colors in
the finished precast concrete parts.
concrete is
usually used in lower end track homes where budget is a concern,
stone is usually used in higher end homes where budget is not a major
concern. The difference between
cast stone and precast concrete is easily seen, and even the novice can
appreciate the high quality limestone like finish on a cast stone product.
Fireplace mantels or as some call them fireplace mantles look beautiful
when constructed from cast stone. The fireplace mantels are both strong and fireproof.
Fireplace mantels are
a thing of beauty when made from precast concrete. Fireplace mantels or fireplace chimneys
are the main feature in any room and a fireplace mantel made from cast
stone or precast concrete is a sight to behold.
