1. An underground storage unit for storing bulk sulfur comprising:
a base layer having a length and a width defining a substantially rectangular shape configured to flex, the base layer comprising leachate collection pipes arranged to form a grid of cells, and high strength sulfur positioned at each cell;
an intermediate layer having a substantially cuboid shape aligned with the cells of the base layer, the intermediate layer comprising high strength sulfur side walls extending from a perimeter of the base layer, and bulk sulfur positioned on top of the base layer;
a top layer positioned at an extent of the side walls and comprising a first sub-layer formed from high strength sulfur, a second sub-layer formed from a rigid moisture resistant material, and a third sub-layer formed from top soil; and
one or more hatches positioned at the top layer that provide access to the bulk sulfur of the intermediate layer.
