Harvested grain, bales and produce often wait in the open, at the farm, the mandi or a warehouse yard, before they move on. A well-chosen, well-fitted tarpaulin keeps rain, dew, dust and sun off them until then.
Start with a raised, dry base
Water comes up from the ground as well as down from the sky. Build the stack on pallets, wooden planks or a raised platform, so the bottom layer is not sitting in wet soil, and put a sheet under the stack if the ground is damp.
Shape the stack to shed water
A flat top lets rain collect, and pooled water is heavy enough to stretch a cover and find its way in. Stack so the top is slightly higher in the middle, so water runs off the sides.

Choose the right size
The cover should reach down each side close to the ground. Width needed = stack width + 2 × stack height + a margin for tying; length needed = stack length + 2 × stack height + the same margin. If one sheet is not big enough, overlap two generously, with the upper sheet over the lower one so water runs across the joint, not into it.
For bulk orders we make custom sizes. See how to measure and order tarpaulin.
Choose the GSM
A cover that stays out for a season in sun and rain needs a UV-resistant sheet and a middle or heavy grade, such as 120 or 150 GSM. Our tarpaulin GSM guide compares the grades.
Tie it down
- Tie the cover down along its reinforced edges on every side, so wind cannot get underneath and lift it.
- Pull it snug but not drum-tight; a cover that flaps wears out quickly.
- Pad sharp corners of the stack where the sheet presses against them.

Check after every storm
Walk around the stack after heavy rain or wind. Re-tie anything loose, clear pooled water and look under the edges for leaks or damp, so a small problem does not spoil the whole stack.
Our tarpaulins for farm storage
Our Indoline multilayer tarpaulins are made from bonded layers of mLDPE, LDPE and LLDPE: 100% waterproof, with a UV-resistant coating and reinforced edges, in 90, 120, 150 and 200 GSM, or any GSM from 70 to 200 on orders of 2 tons. Farmers use them to cover grain sacks, bales and harvested produce in open storage. See our tarpaulin manufacturer in Ahmedabad, Gujarat page.
