Inline fillers have become the workhorse of the concrete industry for several reasons. The first is that they improve efficiency and they do so in two different but important ways. The first way they improve efficiency is that they keep concrete from freezing and they allow water to penetrate deeply into the underlying surface, which brings us to the second important reason. With an inline filler you can be sure that the concrete will have a consistent internal texture and consistent external appearance. When you’re done, no one will know that you used a hand crank inline filler instead of an electric one!
Benefits of Inline Filling Technology
Another very important reason why inline fillers remain the industry standard is that they improve bottoming out operations. When concrete is poured, it starts out at the top like a ball and ends up slowly sinking to the bottom like a pea. This means that when you apply the concrete the surface below the surface becomes uneven and therefore bottoms out at the bottom before the filler spreads over the entire surface and fills in the bubbles. With an above-ground reservoir the filler also spreads the concrete evenly when it becomes saturated before it begins to sink to the bottom like a pea. This allows a tour to take place even with uneven or dirty surfaces and the end result is a professional-looking finish that look as good as or better than poured concrete.
Because of all these advantages, inline fillers remain a leader in the concrete industry. Today’s models use two of the most advanced and efficient technologies ever developed for concrete applications: the gravity ball and the double-fluting piston. Gravity balls are the compromise between cost effectiveness and efficiency. They work well because gravity tends to flatten the surface of poured concrete so the surface area is not too large. The result is that the amount of energy that is required to move the concrete through the pour is minimal so the amount of concrete that is wasted is minimal as well.
