Quick Answer
For a durable storm shelter, use materials that can withstand high winds, heavy rainfall, and potential flooding. Steel, concrete, and reinforced masonry are ideal choices.
Building a Storm Shelter: Choosing the Right Materials
When selecting materials for a storm shelter, consider the shelter’s purpose, size, and location. A steel shelter is a good option, as it can be easily customized and provides excellent protection against high winds and flying debris.
To build a steel storm shelter, use a metal frame with a minimum thickness of 1/4 inch (6 mm). The frame should be anchored to a concrete slab or foundation using anchor bolts. The walls and roof should be made of steel panels, such as corrugated steel or steel sheeting, with a minimum thickness of 18 gauge (0.05 inch or 1.3 mm).
Reinforced Masonry: A Durable Alternative
Reinforced masonry is another durable option for storm shelters. This type of construction involves using concrete blocks or bricks reinforced with steel rebar. The walls should be built using a minimum of 8 inches (20 cm) of solid concrete blocks or 12 inches (30 cm) of hollow concrete blocks. The steel rebar should be spaced no more than 12 inches (30 cm) apart.
Concrete: A Solid Choice for Storm Shelters
Concrete is a popular choice for storm shelters due to its strength and durability. To build a concrete storm shelter, use a minimum of 4 inches (10 cm) of rebar in the foundation and 2 inches (5 cm) in the walls. The concrete should be poured in layers, with each layer allowing time to set before adding the next. The finished surface should be smooth and even, with a minimum thickness of 4 inches (10 cm).
