How to Build a House in a Seismic Zone?


No matter how much-advanced technology mankind has taken into its grasp, earthquake is still one such natural calamity that cannot be predicted. A high measurement on the Richter Scale can bring forth devastation. The last earthquake in West Bengal was of a magnitude of 3.8 in August 2020. And who can forget the earthquake that originated from Nepal that even shook us in Kolkata? So, you need to be prepared to prevent seismic hazards on your building, especially if you are building one in a seismic zone. How do you do that?

You need to follow some tips while you build your house. We have them lined up for you:

1. Go for regular geometric setup

Choose perpendicular wall structure instead of other irregular geometric shapes and angles. Perpendicular structure with symmetrically proportioned walls gives a building the highest strength and enables it to sustain seismic waves. Consult with the best quality TMT bar manufacturers in Kolkata, and they will reply in unison.

2. Rely on the best architect-engineer to design your building

While your house is under construction or in the planning phase, do not try to defy the laws of Physics and do experiments with the structure. Do not think of adding a second plant to a foundation with thin girders and four columns. The results will be devastating. Buildings with overhanging, dimensional changes cannot sustain earthquakes. To ensure this, you must consult an expert architect-engineer who has knowledge of the subject.

3. Check the flexibility of the TMT bars

When it comes to ensuring your home safety against earthquakes, choose only the best TMT bar in West Bengal that comes with greater flexibility and ductility. Check with the engineer and the builder that all elements of the building, such as the slabs, columns, girders, etc., are spliced monolithically to each other.

4. Use seismic-resistant materials

While choosing steel bars for your home, ask the TMT bar manufacturers in Kolkata to come with suggestions of bars that are heat resistant, rust-resistant and, most importantly, resistant to seismic movements, i.e., can absorb the energy produced by an earthquake. Uniformity of the bars and other materials is important as that will give the building strong integration.

5. Check the stability of soil

Once you choose a location for your home, book a consultation appointment with a soil specialist who can analyse the structure of the soil. If the soil lacks stability and is prone to landslides (such as near the hilly areas), the expert will tell you what preventive measures you should take. You might need more pipes, build a slope or design the foundation in some special way. There again, you need to focus on good quality TMT bars, and so, have a good discussion with TMT bars suppliers in Kolkata.

With these top five tips, you can ensure the safety and security of your home against an earthquake, even if it is a seismic zone. Do keep these in mind and discuss the same with your builders.
