What Are Common Mistakes When Setting Up Tarps?

Incorrect Tarp Size and Orientation

When setting up a tarp, ensure it’s the correct size for your needs. A tarp that’s too small can be unstable, while one that’s too large can be unwieldy. For a standard emergency shelter, a 9x12 foot tarp is a good size. When orienting the tarp, consider the direction of the wind and rain to minimize exposure. A common mistake is setting up the tarp with the opening facing the wrong direction, leading to water entry.

Anchoring and Edge Securing

To create a stable shelter, anchor the tarp to sturdy objects such as trees or rocks. Use cordage or rope with a minimum breaking strength of 700 pounds to secure the tarp. Make sure to tie off the edges at least 12 inches from the corners to prevent sagging and water pooling. Use multiple anchors to distribute the force and prevent the tarp from being pulled loose. For added security, use rocks or sticks to weigh down the edges and prevent wind from lifting the tarp.

Tensioning and Stake Placement

Achieving proper tarp tension is crucial for a waterproof shelter. Use a minimum of two stakes per edge to secure the tarp, spaced about 2 feet apart. Drive the stakes in at an angle to prevent the tarp from sagging or bunching up. Use a cord or rope to tie off the stakes and maintain tension. For a more stable setup, use a “ridge line” technique, where a cord is run along the center of the tarp to create a taught, aerodynamic shape. This helps to distribute wind and rain evenly and prevents the tarp from flapping or collapsing.
