Even Product Density

Extended Mold Life

Energy Efficiency

CVT Technology


True vertical vibration provides:

  • even density through the product
  • less cement use
  • lower mold wear


Impact bars from the bottom of the mold leads to:

  • poor height control
  • uneven product density
  • increased cement use in tall products.


Rocking motion of mold creates:

  • uneven product density
  • increased cement consumption
  • higher mold wear.


Columbia's patented vibration technology, CVT, combines 80 years of innovative engineering and field proven designs with industry leading manufacturing capabilities. CVT enables producers to create the highest quality and widest range of products in the world.


Table vibration is commonly found on big board or large pallet concrete products machines. It uses vibrators which are connected to impact bars, these bars strike the bottom of the production pallet to create vibration throughout the product. It is inherently inefficient due to the random motion, which leads to poor height control and non-linear product densities & textures.


Other mold vibration is a style of vibration for concrete products machinery where the vibrators are attached directly to the mold. Because of how these vibration systems work, there is an induced rocking motion caused by out-of-sync vibrators. This motion leads to uneven product densities and overall weak concrete products with inconsistent textures and high mold wear.

  • 70% More Uniform Density

    An independent lab study proves that utilizing CVT provides up to 70% more uniform product density from top-to-bottom and across the production pallet when producing concrete products on a Columbia Machine. This not only makes for a stronger product, but demonstrates the cement savings CVT offers. Less cement usage means less cost, which ultimately leads to higher profits.

  • Total Variation in Aggregate Distribution from Top to Bottom of Concrete Product

  • 10% Less Cement

    With CVT the mold vibration forces are completely uniform top to bottom and across the production pallet. That provides equal compaction of material throughout the entire product and the ability to use less cement compared to other vibration systems.

  • 2X Extended Mold Life

    The true vertical vibration provided by CVT means reduced friction between the shoes and the mold compared to other mold vibration systems. Less mold wear means longer mold life and more money in your pocket.

    Same materials, same mix designs, same product… same overall general conditions, but dramatically different results.

  • Precision Height Control

    CVT offers producers the ability to control the height of their product like no other technology. This precision allows the mason or landscape contractor to lay product faster and more enjoyably in comparison to working with uneven products – but, it also means less material waste for you as the producer. Less waste means more money saved.
