Is It Practical to Use Bungee Cords for Structural Lashings?

Choosing the Right Cordage

When it comes to structural lashings for building shelters, the primary concern is the ability of the cordage to bear the weight and stresses of the structure. Bungee cords, made of elastic rubber or synthetic materials, are designed for shock absorption and not for withstanding significant loads. A single bungee cord may be able to support around 50-100 pounds, depending on its size and rating, which is often insufficient for structural lashings in most survival situations. In contrast, natural fiber cordage like rope or twine can support significantly more weight, making it a more practical choice for structural lashings.

Techniques for Lashings

To build a sturdy shelter, it’s essential to use proper lashing techniques to secure the structure’s frame. In a survival situation, a simple square lashing can be used to tie two poles together, while a more complex diagonal lashing can be used to secure a corner. When using lashings, it’s crucial to space the knots about 6-8 inches apart to distribute the weight evenly and prevent the structure from collapsing. Using multiple lashings and securing them with knots will help to create a stable and secure shelter.

Best Practices for Cordage Selection

In a survival situation, it’s essential to prioritize cordage selection based on its strength, durability, and water resistance. Natural fiber cordage like hemp, jute, or sisal rope is an excellent choice for structural lashings due to its high tensile strength and water resistance. When selecting cordage, look for options with a minimum diameter of 1/4 inch and a tensile strength of 500-1000 pounds. Avoid using cordage with loose or damaged fibers, as it may compromise the structural integrity of the shelter.
