David Liguori, of Bay Area Pervious Concrete (BAPC), and team from the NASA Ames Research Center recently worked together to design a new form of pervious concrete that will be used during inflight missions. This new concrete will aid them in their synthetic tree concept, the Self-Adhearing Bioreactors (SABR).

This project uses a simulated transpiration process to deliver water and nutrients to algal biofilms which grow on porous substrates. That is where pervious concrete comes into play as a strong material that algae can thrive on is necessary:

After researching different concrete products that might solve those two issues Dr. Murphy came across pervious concrete and Bay Area Pervious Concrete. When he contacted us we were all too happy to help the team in their efforts to find a new use for pervious concrete. David, using his advanced knowledge of pervious concrete materials and mix design, created an original prototype to test for the feasibility of algae growth on pervious concrete.
