Yesterday’s blog post introduced the topic of seacrete, also called seament and biorock. Today we’ll briefly look at just a few building components that a do-it-yourselfer could make for very low cost if they live near the sea. Yes, this takes a bit of work, but remember the materials are extremely cheap and the end result is stronger than concrete.
“The biorock building process (called accretion) grows cement-like engineering structures and marine ecosystems, often for mariculture of corals, oysters, clams, lobsters and fish in salt water. It works by passing a small electrical current through electrodes in the water. The structure grows more or less without limit as long as current flows.
