After the walls and floor have hardened, you can build the bunker’s ceiling. A solid ceiling is crucial to provide protection from external influences. You can use a similar technique to the walls by combining cement and steel reinforcement.
Install a ventilation system
An effective ventilation system is essential to bring fresh air into the bunker. You can install ventilation shafts that lead to the outside to ensure air circulation. Make sure that the shafts are well sealed to prevent the ingress of water and dirt. It may also be useful to install a small fan to aid air circulation.
3.4 Interior fittings
Design the interior of your bunker according to your needs. Here are some considerations for the interior design:
- Room layout: plan how many rooms you need. A sleeping area, a storage room for food and water and a small lounge area are recommended.
- Shelving and storage: Add shelving to store food, water and other supplies. Use vertical space to save space.
- Furniture: Choose furniture that is easy to transport and store. Folding furniture or multifunctional pieces of furniture are ideal.
- Lighting: Install reliable lighting that also works during power cuts. Solar lights or battery-powered lamps are good options.
3.5 Safety and emergency supplies
Safety should be a top priority when planning and building your bunker. Here are some important safety precautions:
Emergency exits
Plan a second exit for emergencies. This can be a simple access to another area of the property or a secret exit that can be used in the event of an attack or evacuation.
Emergency supplies
Store food, water and medical supplies. Here are some tips for storage:
- Food: Choose long-life foods such as canned goods, dried fruit, rice and pasta. Make sure you check your food regularly and replace expired products. You can find useful emergency supplies here:
- Water: Store enough water for at least two weeks. A rule of thumb is to plan for at least 2 liters of water per person per day.
- Medical supplies: Make sure you have a well-stocked first aid kit. This includes bandages, painkillers, antiseptics and personal medication.
3.6 Communication and entertainment
It can be quiet in a bunker for a long time. It is therefore important to plan for means of communication and entertainment:
