- Concrete Variation
Why does concrete show variation on the surface and edges?
All of Truform Concrete's concrete products are heat cured for over 12 hours. We use a very low water-to-cement ratio and a considerable amount of mix additives to ensure you are getting the best high strength concrete on the market. Our batching, weighing, and casting process is extremely consistent with all ingredients being measured to the 100th of a gram. Trueform is and has always been dedicated to perfecting the art of casting amazing concrete products.
Even with all these processes, structures, and protocols in place; concrete projects still exhibit variations and random markings. Why is your concrete imperfect?
There isn't one particular reason why concrete products show surface and edge variations. The first step to understanding “why” is to understand that this material is a finished product of a chemical reaction called hydration. (click the link for scientific explanation) A lot of chemical reactions occur within concrete during the curing process which affect the final surface as well as the integrity of the product. Moisture and heat escape the concrete, leaving behind a visual story on the surface and edge of your project. Two other factors that have a huge impact on the product are the casting process and the artisans touch. Both add their own chapters to the concrete production story.
What you may see as an unacceptable blemish is simply the evidence of the story in which your concrete project was created. If that variation was not present, the product would be void of the integrity to what it is… Hand Made… We lead our industry in excellent quality control over our casting process. Sometimes you just have to accept that concrete is hand made and has variation to it that we can't control.
Below are some examples of concrete surfaces and edges that show a type of variation that you may see on your concrete project. Several of these photos are from our New Jersey showroom and are considered completely acceptable within our industry.
