Pouring the floor is another step in the construction process that requires expertise to do. Because good floor pouring must have both a balance of the area that can be used for real, a strong floor layer for long-term use, using quality concrete for the work, including smoothness and beauty to proceed to the next step without interruption. But many times, some steps of the floor pouring work may be done by technicians out of familiarity rather than the correct method. At this point, there may be some errors that affect the work later.
Therefore, to prevent the repetitive rework loop, this content presents concrete floor pouring techniques that should be known to ensure that the work goes as desired by both the contractor and the homeowner.
5 Concrete Flooring Techniques You Should Know
1. Adjust the area before pouring concrete.
The initial stage of pouring a floor should begin with leveling the ground. Generally, the floor of a house must be filled 50-80 centimeters higher than the road. Therefore, the sand and soil in the area must be compacted as tightly as possible to prevent the sand from collapsing when the concrete is placed. When the ground leveling process goes well, the next stage of pouring a floor will follow the plan, both in terms of time and the amount of materials allocated appropriately.
2.Determine the appropriate amount of concrete
The amount of concrete required is something that needs to be determined from measuring the area in several places because if the amount of concrete is not the same as calculated, it will waste time ordering more concrete when the amount is short, and there may be a problem of the additional concrete poured not cohesive with the previous batch. As for the concrete mixing formula, it is equally important for floor pouring work. Generally, the ratio of cement: sand: stone = 1: 2: 4 should be used to make the concrete efficient enough to bear the weight.
3.Place the concrete reinforcement correctly.
Next is to place a suitable set of reinforcing steel gratings. This reinforcing steel will help increase the strength of the concrete pouring work even better, and help reduce cement cracking when the temperature changes from day to night. The steel should be placed no more than 5 centimeters below the concrete surface. To prevent the steel from touching the ground, cement balls can be used to support the steel grating at regular intervals.
4.Prepare a stable and strong concrete mold.
Some people may overlook this, but do you know that the concrete formwork is just as important for floor pouring? Because the concrete formwork helps support the poured concrete to stay in place as it should be. The characteristics of a good concrete formwork must be strong and have the correct support points to prevent the concrete from spilling out along the joints and prevent the points where the concrete can leak out.
5.Leave clear seams to prevent cracking.
Because concrete can expand and contract according to the temperature changes, the spacing of the joints in the cement in the floor pouring work is like setting the distance for the concrete to crack along the set marks. The joints in the floor can be divided into 2 types: "Joints between the floor and the wall", which is the distance between the joints that help reduce the problem of expansion that may cause uneven settlement, and the second type is "Joints in the floor", which helps reduce the problem of concrete expanding or contracting and cracking.
Efficient concrete pouring
For concrete pouring work, in addition to the quality of good reinforced concrete, the work process is also an important part that makes the pouring work come out well. Because each step or some techniques of pouring work are important factors that make the concrete floor strong, durable, and usable for a long time. Importantly, it also helps prevent problems during the work and finishes well afterwards so that residents can use it as it should.
