• Learn Exactly How Architectural Cast Stone is
  Made
• Stone architecture has an old world charm and
  beauty that have sustained since ancient times.
  It gives a home a very stately look that speaks
  of status and class. Stonework is the most
  popular choice for laying decorative flooring,
  fireplaces, mantels, pillars, patios, building
  facades, porticos, garden fountains, pathways,
  etc. There are two main manufacturing techniques
  used in creating cast stones wet casting and
  semi-dry.
• Method of making wet cast stones
• A Wet Cast Stone is an architectural concrete
  stone that is precast to look like natural a
  stone. The cast stones are easily available as
  they can be created on demand. They are less
  porous than some of the natural stones. Hence,
  over the centuries, wet cast stones have gained
  popularity.

• Wet Cast Manufacturing is a simpler method of
  creating architectural stones. Using the same
  machinery one can create a wide range of cast
  stone products. This is very advantageous for a
  small-scale manufacturer because his overheads
  and operating costs are lower. This manufacturing
  method is very simple
• Pre-determined measures of cement and
  rough-grained sand are mixed with water and other
  binding and/or hydrating materials,
• This mixture is poured into moulds that are
  placed on vibrating tables,
• The vibration allows air bubbles to escape,
• The surfaces are evened out with a rake to give
  the stones a smoother look,
• The moulds are then moved to a flat area and left
  to cure.
• Large companies involved in the manufacture of
  wet cast stones usually focus on stones with
  unusual combinations that look different from the
  standard wet cast stones. They mix a variety of
  colored concrete and use their own customized
  moulds to create architectural stones with
  extraordinary designs and patterns. This is
  usually the high-end variety of wet cast stones
  used in building construction. They are exclusive
  in the look meant for the elite.

• Semi-dry cast stones as an alternative
• Semi-dry cast stones are more in demand than wet
  cast stones as they are hardier. They are used in
  places where there are greater chances of wear
  and tear but fewer loads like
• Outer façade,
• Garden,
• Pathway,
• Verandah,
• Patio, etc.
• The purpose for the use of stone is more
  aesthetic than load bearing. As the name Semi-Dry
  Manufacturing suggests, these stones are made
  from naturally moist mixtures without adding more
  water. The combination of raw materials is
  decided on how grainy you want the finished
  product to look. A smoother finish would require
  a mixture of finer sand. For the rough and
  natural look your semi-dry stones need coarser
  sand.

• Wooden moulds are used to create different types
  of semi-dry cast stones. The moulds are kept in a
  face-down position. The mixture is poured in, and
  pneumatic rammers are used to press the mixture
  firmly into the moulds. This ensures that all the
  air bubbles are let out otherwise there will be
  ugly gaps in the finished stone. This method has
  an advantage over wet cast stones as the final
  pieces are more consistent and the products have
  a higher level of finesse.
