Benefits of Fiberglass Underground Storm Shelters

One of the benefits of fiberglass underground storm shelters is that they’re incredibly durable and long-lasting. Fiberglass is renowned for its strength and resilience, making it an ideal material for constructing storm shelters.

Unlike other materials, fiberglass is resistant to corrosion, rot, and damage caused by pests, ensuring that the shelter remains intact and functional for an extended period.

Installation Process of Fiberglass Underground Storm Shelters

The installation process of these shelters involves carefully positioning them in the desired location. Once the location is determined, the following steps are taken:

  • Excavation: A hole is dug in the ground, ensuring it is deep enough to accommodate the shelter and comply with building regulations.
  • Foundation preparation: The bottom of the hole is leveled and compacted to provide a stable base for the shelter.
  • Shelter placement: The fiberglass storm shelter is carefully lowered into the hole, ensuring it fits securely and aligns with the hole’s edges.
  • Backfilling: The space around the shelter is filled with soil, compacted in layers to provide additional support and prevent shifting.

When considering the cost comparison between fiberglass and concrete storm shelters, fiberglass is often more affordable due to lower material and installation costs. However, building permits and regulations must be adhered to when installing underground storm shelters to ensure proper safety measures are followed.

Maintenance Tips for Fiberglass Underground Storm Shelters

When it comes to maintaining fiberglass underground storm shelters, it’s important to regularly inspect and clean the interior and exterior surfaces.

Fiberglass underground storm shelters are constructed using layers of fiberglass and resin, providing a durable and long-lasting structure. One of the advantages of fiberglass storm shelters is their resistance to corrosion, making them ideal for underground use.

To maintain the shelter, start by inspecting the interior for any signs of damage or wear. Check for cracks, leaks, or any loose fittings. Clean the interior with a mild detergent and water solution, using a soft brush or cloth.

For the exterior, inspect for any damage or deterioration. Clean the surface using a non-abrasive cleaner and rinse thoroughly.

Regular maintenance will ensure the longevity and effectiveness of your fiberglass underground storm shelter.

Choosing the Right Size Fiberglass Underground Storm Shelter

To choose the right size for your fiberglass underground storm shelter, take into account the number of people it needs to accommodate. Consider the following factors to ensure you make an informed decision:

  • Square footage: Determine the required square footage based on the number of occupants. The general rule is to allocate around 10 square feet per person.

  • Height: Consider the height of the shelter to ensure everyone can stand comfortably inside. A minimum height of 6 feet is recommended.

  • Storage space: Evaluate the amount of storage space needed for emergency supplies and personal belongings. Consider shelves or compartments for organization.

  • Accessibility: Ensure the shelter is easily accessible for all occupants, including those with mobility challenges. Consider factors such as entryway size and the need for ramps or handrails.

Avoid common mistakes such as underestimating the number of occupants or overlooking the need for storage space. Additionally, factor in cost considerations when selecting the size, as larger shelters may require a higher investment.
