Concrete

It's important to be aware of the cost of Concrete in the game. It takes 12 Concrete to make one Concrete Foundation, and a single Concrete Foundation is made up of 5 x 5 floor "blocks." Each Concrete floor block requires 16 Concrete to make. Concrete is made from 4 Rocks. To lay down a concrete floor on a Concrete Foundation, it takes a total of 412 Concrete, or 1648 Rocks. Each Rock resource takes about 40 seconds to harvest on Beta Prairie and yields 20 items, which is a mixture of Rocks and Flint, roughly 75% Rock and 25% Flint. This means it could take several hours of breaking rocks to be able to set the floor of your base.
Instead, Concrete can be purchased from the Industry merchant, which can be found on orbital space stations.
