Quick Answer
Ensure adequate drainage with your tarp setup by angling the tarp to allow water to run off, using stakes to secure the tarp and prevent water from pooling, and creating a slight slope in the center to direct water away from your shelter.
Creating a Water-Repellent Tarp Surface
To ensure your tarp remains watertight, apply a thin layer of wax or silicone-based spray to the underside of the tarp. This will help prevent water from seeping through the fabric. For a more durable solution, apply a thin layer of a waterproof coating, such as Nikwax or Scotchgard, to the tarp’s surface.
Staking the Tarp for Adequate Drainage
When staking the tarp, ensure the stakes are driven at an angle to prevent water from pooling around the edges. Aim to drive the stakes about 6-8 inches deep into the ground, depending on the soil type, to provide stability and prevent the tarp from shifting in windy conditions. Leave a slight gap between the tarp and the ground to allow water to run off and prevent it from accumulating.
Sloping the Tarp for Water Runoff
To direct water away from your shelter, create a slight slope in the center of the tarp by adjusting the stakes or using rocks to hold the tarp in place. Aim for a slope of about 1-2% to allow water to run off effectively. This will help prevent water from accumulating around your shelter and reduce the risk of flooding or water damage.
