What is Floor Plate?

The floor plate functions as a level barrier between floors.

Floor slab is a floor that is not directly above the ground. In other words, the floor plate is the dividing level between the lower floor and the floor above. In its manufacture, the floor slab is supported by beams that rest on the building’s columns.

When using floor slabs to build a house, the thickness varies and is determined by several factors including:

  •     Desired amount of deflection (downward curvature)
  •     Width of distance between support beams
  •     Construction materials and floor slabs
  •     The amount of load that must be supported.

Now you know what a floor plate is. But if you really plan to build a house and don’t have your own land to build.

Floor Plate Function

The floor plate is able to make the building structure stronger.

From the explanation above, we already know that the main function of the floor slab is as a separator between the first floor and the second, third, and so on. Not only that, the floor plate also has other functions, namely:

Able to strengthen the building structure

  •     Receiving loads to be transferred to other structures
  •     As a silencer from the top floor to the bottom floor
  •     Where to install electrical wiring and lights for the lower floor
  •     Increases building rigidity from the horizontal direction

With its function which is quite fundamental in the building, the floor slab must be designed rigidly, flat, straight, with a waterpass (the height is the same and must not be tilted).

Floor Plate Type

Concrete floor slabs are the most chosen because they are more sturdy.

As a foothold on the top floor, the types of floor plates are distinguished based on the material they are made of. In general, there are 3 types of floor plates, namely:

 Concrete Floor Slab

This type of plate is made of reinforced concrete with a horizontal plane direction made of a mixture of cement, sand, gravel, water, admixture. The provisions regarding this plate are stated in the 1991 SNI I Concrete book which includes the minimum thickness of the floor plate, which is 12 cm and 7 cm for the roof plate.

The thickness rule of the plate must be filled with reinforcing steel or medium steel cross-stacked with a diameter of 8mm.

It should be noted, if you use a concrete floor slab, make sure the steel reinforcement is wrapped in concrete with a thickness of at least 1 cm. Meanwhile, the ideal distance between concrete reinforcement is about 2 times the thickness of the plate used.

Wood Floor Plate

As the name implies, this type of floor plate is made of wood that is assembled and firmly united to become a large area of ​​​​stepping. Usually, the wooden planks used are 2-3 cm long and 20-30 cm wide. As a support, wooden floor slabs use beams measuring 8/10, 8/12,10/14 with a distance of 60-80 cm.

Wooden floor slabs are often chosen as an alternative because they are relatively cheap, easy to work with, and can save on the size of the foundation. However, wooden floor slabs are only suitable for use in simple and light construction structures. In addition, the material is flammable, not waterproof, can not be installed ceramics, and is not a good absorber.


 Cement Floor Plate

Also known as yumen floor plate, this type is made of 80×90 cm pieces of wood mixed with cement. To build it, first install bengkirai wood size 5/7 with a distance of 40 cm. After that put the ring balk on it and then cast it with concrete. Cement wood sheets that have been finished are then arranged tightly on the concrete and bolted to make it stronger. On the other hand, this type of plate is still new and has not been widely used.

Tips for

Make sure the diameter of the concrete for the floor slab fits so that it doesn’t collapse easily.

Advantages and Disadvantages of Floor Plate

Although cheap, wooden floor slabs are not waterproof.

In the previous discussion, you have seen that although the construction cost is relatively cheap, water is the main weakness of wooden floor slabs. This time we will discuss the advantages and disadvantages of concrete floor slabs, including:


  •     The construction is able to support heavy loads
  •     Non-flammable and water-resistant
  •     Able to be good sound insulation
  •     Relatively durable and does not require much maintenance for several years
  •     The surface can be installed with ceramics / tiles that beautify the room


  •     The installation costs more than the type of wooden floor plate and requires heavy equipment
  •     Difficult to repair if there is damage and even if patched the results will not be as smooth as before
  •     Easily damp and mossy if the concrete floor slab is made uneven and perforated
