The function of the anti-earthquake foundation is not very different from the foundation of a house in general. However, the benefits far exceed the usual basis. Do you want to try it?

Both types of foundations maintain the key and the main strength of all parts of the building during its life.

On the other hand, the foundation of the house to withstand the shocks of the earthquake must be done carefully. For what?

To have an earthquake-resistant building, you have to start from an earthquake-resistant foundation that makes all the parts of the house into a unified whole.

A good earthquake-proof foundation has a system that firmly connects one part of the house to another.

So, how to make a good and correct anti-earthquake foundation so that the house can withstand earthquakes?

Quoted from the page antigempa.comThis is how to make a proper and strong anti-earthquake foundation.

Foundation work techniques

Before starting to build an anti-earthquake foundation, there are several things you need to understand and prepare for the process to go well.

Some of the things that need to be understood are:

  • Dig the soil to a depth of about 70 cm, then make a wall of soil in an inclined position with a ratio of 5:1 so that the soil can hold firmly.
  • Cover the bottom of the excavation with sand to a depth of 10 cm.
  • In making the foundation, try to reach a height of 45 to 60 cm.
  • If the foundation is made with river stone, then the mixture must be made with a ratio of 1 cement: 4 sand.
  • When building continuous foundations, sloofs must be made every 1.5 m with steel reinforcement of 12 mm diameter.
  • Finally, put a sloof or a foundation beam on the foundation so that the load is distributed more evenly. Slof should be made of 1 cement: 2 sand: 3 gravel and water half the volume of cement.

5 Ways to Build High Quality Earthquake Resistant Foundations

1. Build earthquake-resistant foundations on hard ground

In order for the building to remain stable and strong, the foundation must be made on hard and solid ground.

The reason is, the main function of the foundation is to transfer the load of the building to the surrounding land, so that the building can survive well.

If the soil around the construction site is considered to be less hard and less stable, the soil needs preliminary work to strengthen the soil layer.

After the soil for the construction has been dug, leave the soil for a few days and then water and compact it manually so that the soil becomes more stable.

If there is even less, add a layer of stone sand to the base of the foundation and compact it with a stamper.

2. Plant Anti-Earthquake Foundation Deep Enough

In general, anti-seismic foundations use a continuous stone foundation system that can connect the foundation with the sloof.

To make it stronger, make a foundation of river stone at a minimum depth of 45 cm from the surface of the earth for a house consisting of one floor.

While for a two-story house, place the foundation at least at a depth of 60 cm from the surface of the earth to make it stronger.

For its durability to be more guaranteed, you can also add a foot foundation or good foundation in some foundation places.

3. The Anti-Earthquake Foundation is made continuously

The key to a house that is earthquake-resistant is that an earthquake-proof foundation must be made continuously without interruption.

Don’t just do it for cost saving reasons, reduce the foundation material and don’t do it in a continuous form.

This will make the resistance of your house to earthquakes not very good and have bad consequences for the buildings when an earthquake occurs.

The bad effects that can be caused can be very dangerous because apart from cracking the walls of buildings, they can also cause a collapse of buildings.

4. Make Anti-Earthquake Foundation Binding Blocks

If the stone base has been made, the next step is to make sloofs or foundation binding blocks made of concrete.

The main function of the sloof is to distribute the load of the building evenly throughout the body of the foundation.

The use of this sloof is also not only applied to continuous foundations, but also used in local foundations.

In the stone foundations of the river, make sure that the sloof remains firmly on the foundation by tying the body of the sloof with anchors half a meter long.

The binding beams of the foundation also strengthen the river stone foundation so that it becomes a very strong anti-earthquake foundation.

5. Attach the Foundation, Sloof, and Columns to each other

The last step to make an earthquake-resistant foundation is to tie all the foundations, sloof and columns.

Make sure that all these parts are firmly connected and well integrated, especially on the metal parts.

This step is very important because if all the parts are well connected and integrated, when an earthquake occurs, the vibrations can be spread evenly.

The vibrations of the earthquake will be well distributed to all parts of the building and other parts of the construction and the building will not collapse.
