Hauled material for a stronger late wall. Confirm costs, drop rates, and unlocks in the live Stop The Tsunami! experience.
Player wiki for Stop The Tsunami! on Roblox: sand walls, trenches, machines, materials, co-op roles, and the code box.
Gravel is the first late-game material named for stronger walls. You haul it once the beach is wide enough that plain sand is no longer the whole defense.

Haul it on the full beach. The dump truck is the published hauling machine.
Add gravel after the sand line already covers the approach. Hauling it before the line is closed wastes the round.
Claim the Daily Spin and daily rewards, then build a continuous packed sand wall with a trench before you press START ROUND. Spend the coins from waves you hold on the next tool you can actually use.
