Grasscrete – Good For Earth And Creative Minds

This project won the 2018 Bomanite Gold Award for Best Grasscrete Project installed by Premier Concrete Construction.  This backyard, adjacent to an Artists/Musicians studio located in Massachusetts, required an access area to accommodate large delivery vehicles.  More importantly, it required a permanent solution to storm water management and yet still maintain landscape aesthetics necessary to help nurture the creative minds of the occupants.

Grasscrete Pervious Concrete installation subbase prep work to ensure storm water management characteristics of Grasscrete.Grasscrete was the perfect Pervious Concrete solution.  Not only can Grasscrete augment the landscape architecture and handle the storm water of this project, but has the added benefit of a very long lifespan.  The project incorporated 3,000 square feet of Grasscrete.  A subbase was prepped to facilitate storm water management via proper drainage and to create the outer forms of the project.

A view of the Grasscrete Pervious Concrete single-use Molded Pulp Formers in place with rebar as reinforcement in both directions before a crew begins pouring concrete.Next, the single-use Molded Pulp Formers were placed with rebar in both directions which gives Grasscrete the highly desired characteristic of being continually reinforced.  Special attention was needed to ensure the straightness of the formers because any misalignment will be magnified by any rows of grass planted into the voids.  This is critical prep work before the concrete pour.  The concrete is then poured, leveled, broom finished, and allowed to dry.

Grasscrete Pervious Concrete is biodegradable and environmentally friendly and a crew member sprays the project after the voids are created to initiate that process.The Molded Pulp Formers are biodegradable. To clean up the project and to initiate the biodegrading process, after the voids were punched, the entire project was pressure washed.  Grasscrete is an environmentally friendly Pervious Concrete solution.  What’s next for this project?  At the time of installation, the owner was contemplating having half of the Grasscrete fully Concealed and the half closer to the building Partially Concealed.
