Quick Answer
Position a lean-to on a slope with the entrance on the uphill side, facing away from the wind, and the lowest side of the lean-to on the down slope. This ensures stability and reduces water runoff. Anchor the structure securely to the ground.
Choosing a Slope Angle
When selecting a slope for your lean-to shelter, look for an angle that’s not too steep. A slope of 1:6 to 1:8 is ideal, as it provides sufficient drainage and stability. Be cautious of slopes steeper than 1:3, as they can be prone to landslides and structural instability.
Positioning the Lean-To
Position the entrance of the lean-to on the uphill side, facing away from the wind. This will help you avoid wind-driven rain and debris. Make sure the lowest side of the lean-to is on the down slope, allowing water to run off without entering the shelter. Securely anchor the structure to the ground using sturdy stakes and ropes.
Building a Stable Foundation
To create a stable foundation for your lean-to, dig a shallow trench (about 6-8 inches deep) on the down slope side. Fill the trench with compacted gravel or sand, and then lay a flat, sturdy board on top. This will help to distribute the weight of the lean-to evenly and prevent it from shifting or collapsing. Anchor the board securely to the ground using stakes and ropes.
