Building a tunnel is a tough task especially if you are doing it at your home. So, how to build a tunnel from house to garage, and what are the important considerations that one needs to keep in his mind while digging the tunnel?

We will describe the whole procedure of building the tunnel from the garage to the house. Furthermore, we will also cover the major problems and security issues that you have to cope with during your construction project.

How to build a tunnel from house to garage?

There is a complete planning and project guideline that is involved in constructing a tunnel from the house to the garage. We will now discuss the complete procedure with a step-by-step guide that will be really helpful in case you are looking to build a tunnel for your house.

Plan Your Tunnel Route:

The first step for building a tunnel is actually determining its exact route from the house to the garage. While planning this route, you have to keep things in mind like the boundaries of the property, any preset building structures, and any utility line’s positions. Therefore, You may need to consult with the geologist or engineer to plan its route. Make a detailed map or blueprint of the tunnel that you have planned and want to design.

Take necessary permits from the Government:

After finalizing your route, next you have to take permission from local government bodies. They will further guide you about the permit you need for constructing a tunnel from your house to the garage. Usually, you need a permit from the zoning and construction department of your local government.

Start Excavation under the supervision of the Engineer:

Now, you can start excavating the route that you selected for this tunnel. While removing the soil, you have to be careful regarding the utility lines and boundary of the tunnel. Furthermore, this process of excavation involves precise measurement of the length and depth of the tunnel.

Installing the Supporting Beams and Blocks:

In the next step, you need to install the major and basic supports that will hold the excavated site in place. Usually, these supports are wooden blocks and beams that you should install to support the structure.

Setting up the Flooring and Side Walls:

Now, you need to construct the flooring and side walls of the tunnel. For this purpose, you need to use concrete material to have solid stability for the tunnel. The material includes strong and heavy iron bars, Steel enforcements, cement, gravel stones, and sand. Keep in mind that do not do this at your thoughts and hire a professional civil engineer for this purpose that can guide you on how to build a tunnel from house to garage.

Leave the structure for a few days:

Next, after setting up strong concrete flooring and side walls, you should not work for the next 10 to 15 days. This is for the concrete and steel enforcements to intact each other and settle down properly.

Building the Roof of Tunnel:

In the next step of how to build a tunnel from house to garage process, you have to build the roof of this tunnel. However, like you used steel and iron bars with concrete for flooring and side walls, roofs also require proper structure with concrete and iron rods giving the strength and stability it needed. You can also use concrete slabs of bigger size for setting up a strong roof.

Decorating the internal Walls, Ceiling, and Floor:

Once the grey structure of the tunnel is ready, you can take further steps of decorating it. However, it depends now on which purpose you have built this tunnel. For general use, you can just leave the flooring with concrete and decorate the side walls with beautiful designs and structures. However, if you want a fully decorated and customized beauty of the tunnel, you have to put tiles and a ceiling of beautiful art on your tunnel.

Refill the outer side of the Tunnel:

After decorating it from the inside, now you can refill the excavation site that needs fillings from the roof and side walls. Plain the upper upper side of the tunnel and you can design a beautiful lawn on it. That is if you are looking at how to build a tunnel from house to garage.

Problems you might face while digging a tunnel:

Now, we discuss the major problems that you might face while digging a tunnel from your house to the garage.

• Local Government Permits:

One of the major problems that you might face is the non-issuance of a permit for digging a tunnel. Each city in the USA has its own rules and regulations regarding digging tunnels more than your waist height. So, you might live in a city where building tunnels is banned. So, this is the first major problem you may face in your project.

• Shortage of Funds:

As we know, building a tunnel is way more expensive than building a home. So, here lies the second big problem which is a shortage of funds for carrying on the project. Therefore, it is advisable to first make an assumption of money that will be spent to complete this project from a civil engineer.

After you complete satisfaction and when you have enough resources and money, start building this tunnel project. Then you will understand how to build a tunnel from the house to the garage.

• Managing the soil of Excavation:

While digging the tunnel, a big issue is where to deposit the soil for excavation. Because it is confirmed that you will get mountains of soil beside the tunnel. Therefore, you have to make a plan before starting the project regarding managing the soil of excavation from the site.

Important Considerations to Make a Tunnel from House to Garage:

Following are the key considerations that you should definitely deeply look into before starting this project.

• Hire an Experienced team of Engineers:

You should first consult with a team of highly professional engineers that have a great experience in their respective fields. This team of engineers includes Civil Engineers, Geologists, and Architecture Engineers. A civil Engineer will guide you regarding the construction material quality, and quantity, and how to build a tunnel from house to garage with a strong base.

On the other hand, a geologist will test the soil and ground level. So, he can better guide you on the depth and ability of the land to withstand the tunnel. This is another important member of your team for construction.

Finally, an architectural Engineer will help you in designing the blueprints and maps of the tunnel. Therefore, when all your team members will be on a single page, you can start this project. You can also put your suggestion forward to these team members to look for other better designs, positions, and construction of the tunnel.

Quality of the Construction material:

The next thing that is very important is the quality of the construction material. A civil engineer will guide you to buy high-quality materials like concrete, Bricks, gravel stones, Steel rods, and iron bars. Because it will definitely enhance the safety and stability of the tunnel.

Keeping mind the Utility lines underground:

While the work is in progress, you should keep checking that underground utility lines are not damaged or disturbed. It is important you do not put other people in disturbance because of your project.

FAQs

Q. How much does it cost to build a small tunnel?

The cost of constructing a tunnel depends on the quality of the material, design, and size of the tunnel. Usually, a tunnel can cost you $1.50 to $2.50 per square foot. Note, these charges do not include the freight charges and cost of labor.

Q. How do you build a tunnel without it collapsing?

The use of quality materials with the latest designs helps in building a tunnel that does not collapse. For this purpose, the use of high-quality metal is important.

Q. How do you dig a tunnel by hand?

For digging a tunnel by hand, you need tools like shovels, a hammer, and a chisel. But this process can take years and years to complete a 500-meter tunnel.

Q. How long does it take to build an underground tunnel?

Normally, a half-kilometer tunnel can take up to 14 months to complete if you work 10 hours each day. But working 24 hours a day, it will still take around 6 months to complete.

Bottom Line:

The process of building a tunnel involves complex procedures and requires permission from government bodies. However, we have described the whole procedure of how to build a tunnel from the house to garage with proper details and research. Furthermore, we discussed many problems that one might face while completing his project.
