5 Techniques in Concrete Floor Construction

Constructing a concrete floor involves a series of crucial techniques, each contributing to the floor's durability, levelness, and finish. These techniques are essential in ensuring a high-quality concrete floor suitable for a variety of uses. Here are five commonly used techniques in concrete floor construction, including screeding, vibrating, and troweling.

Preparation and Pouring of Concrete

The first step involves preparing the sub-base and creating a formwork to hold the concrete. The sub-base must be compacted and leveled to ensure a stable foundation. Once the formwork is in place, concrete is poured into the designated area. The quality of the concrete mix and the pouring technique are critical factors that affect the strength and finish of the floor.

Concrete Screeding

Screeding is the process of leveling the poured concrete. It involves using a screed toola flat board or a specialized toolto smooth out and level the concrete surface after pouring. The screed is moved back and forth across the surface to flatten and level the wet concrete, removing excess and filling in gaps. This step is vital to create a uniformly flat surface before the concrete begins to set.

To eliminate air pockets and ensure a dense, compact slab, vibrating is performed shortly after pouring and screeding. A concrete vibrator is used during this process. It deeply penetrates the wet concrete mix and vibrates at high frequency to consolidate the concrete, pushing air bubbles to the surface and enhancing the bonding of the concrete mixture. This process increases the structural integrity of the floor.


After screeding and vibrating, floating is performed. This process involves using a float, either a hand tool for small areas or a power float for larger areas, to smooth out the surface. Floating helps in pushing down the aggregate and bringing up the cement paste to create a smooth, level surface. This step also prepares the concrete for further finishing processes.


Troweling is the final finishing process, usually done when the concrete has started to set but is still workable. A trowel, which can be a hand tool or a power trowel for larger projects, is used to create a hard, smooth, and dense surface finish. This process is critical for the aesthetic look of the floor and its longevity. In some cases, multiple passes with the trowel may be necessary to achieve the desired finish.


In conclusion, constructing a concrete floor is a complex process that requires skill and attention to detail. Each technique, from the initial pouring to the final troweling, plays an integral role in achieving a durable, level, and aesthetically pleasing concrete floor. Mastery of these techniques is essential for any professional working in the field of concrete floor construction.

  1. Techniques in concrete floor construction involve various methods for preparing, pouring, finishing, and maintaining concrete surfaces. These techniques include proper sub-base preparation, reinforcement placement, concrete mixing, pouring, leveling, and finishing processes to ensure durability, strength, and desired aesthetic qualities in the finished floor. Additionally, sealing, polishing, or coating applications may be employed for added protection and enhancement of the concrete surface.
