CUSTOM ARCHITECTURAL LIMESTONE AND CAST LIMESTONE
What is Limestone?
Limestone is a type of sedimentary rock found in deposits all over the world and used in an assortment of ways. Limestone has been a worldwide building stone of choice for centuries. The long history of limestone construction demonstrates that it endures the elements and actually improves with age. Limestone is relatively uniform in composition, texture, and structure and is easily machined.
What is Cast Limestone and how is it different then Pre-Cast Stone?
Cast Limestone is a mixture of highly refined crushed natural limestone mixed with portland cement as a binder. Since the main ingredient is actual limestone, our product has the look of natural limestone. The advantage of using cast limestone vs. actual limestone is the price. Although no man made material can reproduce exactly what “Mother Nature” can, it’s an excellent substitution.
Cast Stone is very much like cast limestone with the exception of the crushed limestone (a courser dolomite aggregate is used in place of limestone). With cast stone a variety of mineral oxide color pigments can be added to make just about any shade of color. We carry 9 stock colors but can make infinite custom colors.
Every piece of our cast limestone is custom made by hand, by quality craftsmen and mold fabricators with many years of training and hands on experience necessary to turn out a high quality product. When properly designed and manufactured both Cast Limestone and Cast stone are an excellent substitute for natural cut stone with same or better physical and esthetic characteristics at a fraction of the cost and time.
Cast Stone Colors
Is Pre-cast concrete the same as Pre-cast Limestone?
The short answer is no. Pre cast concrete is just that….colored concrete. It is a solid material with a thin coating of concrete paste. This material cannot be modified without having to refinish the exposed areas. Cast stone is a solid material as well, but the difference is cast stone is the same “sugar cube” look throughout. So this can be cut in field without needing any further finishing. Although the two materials are frequently confused, the cast stone’s superiority vs traditional Pre Cast is that cast limestone and cast stone has the color and aggregate matrix consistency throughout.
If Pre Cast is chipped, that area will be noticeably different than the rest. The reason being is Pre Cast develops a smooth Portland coating that covers up the aggregates within, a coating that is susceptible to spider cracks, unsightly chips and freeze and thaw cycles deterioration, where cast limestone is not, It’s the same look throughout. It looks behaves and ages similarly to natural limestone. So if modifications are needed, it can be done on site without any further finishing needed. Cost. There is no significant savings between Cast Stone and Pre Cast Concrete.

CAST LIMESTONE AND CAST STONE MANUFACTURING
Our cast limestone is produced with a low water-to-aggarate ratio with a “dry” consistency. The mixture is consolidated into a mould using tamping equipment under pressure, which is much like the formation of natural sedimentary rock. This process is called vibrant-dry-tamped (VDT).
