Can I Use a Tarp as a Ground Cover While Building?

Securing the Tarp

When using a tarp as a ground cover, start by laying it flat and overlapping it by 12-18 inches to prevent water from seeping under the edges. Use rocks, logs, or sandbags to weigh down the tarp, and ensure it’s tightly stretched to prevent sagging. A minimum of 4-6 stakes or anchors per side will provide stability, depending on the wind conditions.

Ground Drainage and Tarp Placement

To prevent water accumulation under the tarp, create a slight incline for the ground, allowing water to flow away from the building site. Position the tarp at a 10-15° angle to ensure water runs off and doesn’t pool under the fabric. This angle will also help to shed water and prevent it from seeping into the building.

Waterproof Roofing and Additional Protection

Once the tarp is secure, focus on building a waterproof roofing system to provide added protection from the elements. Use a waterproof membrane, such as a plastic sheeting or a waterproofing spray, to cover the roof’s surface. Additionally, consider installing a roof overhang to prevent rain from entering the building site through the sides.
