Quick Answer
To minimize water pooling under a tarp, use a slight slope, ensure the tarp is adequately anchored, and consider adding a waterproof underlay like a plastic sheet or tarp liner. This setup helps to redirect water away from the center and maintains a dry space.
Tarp Placement
When setting up a tarp, it’s essential to create a slight slope to allow water to run off. Aim for a 10-15 degree incline, which is achievable by adjusting the stakes or using rocks to elevate one edge. This subtle tilt enables water to flow towards the edges and away from the center.
Anchor Points
Adequate anchoring is crucial to prevent the tarp from flapping in the wind, which can exacerbate water pooling. Use a minimum of four anchor points, spaced evenly apart, to secure the tarp. Consider using tree straps, rock anchors, or snow stakes, depending on your environment. Make sure the anchors are tied at a 45-degree angle to the tarp to prevent water from accumulating.
Waterproof Underlay
Adding a waterproof underlay like a plastic sheet or tarp liner can significantly reduce water pooling. Place the underlay beneath the tarp, ensuring it’s tightly secured to the ground or anchor points. This extra layer helps to channel water away from the center and prevents it from seeping through the tarp material.
