grasscrete

Grasscrete is a permeable paving material that combines concrete with vegetation. It typically consists of concrete slabs with voids or openings that are then filled with soil and planted with grass or other low-growing groundcover. This creates a surface that is both structurally sound for vehicular or pedestrian traffic and aesthetically pleasing due to the presence of greenery.

The primary advantage of grasscrete is its permeability. Unlike traditional solid concrete or asphalt surfaces, grasscrete allows rainwater to infiltrate the ground directly. This helps to reduce stormwater runoff, which can contribute to flooding and pollution in waterways. By allowing water to soak through, it also replenishes groundwater supplies.

Grasscrete offers a more environmentally friendly alternative to conventional paving methods. The vegetation component can help to mitigate the urban heat island effect by providing shade and through evapotranspiration, which cools the surrounding air. It can also contribute to biodiversity by providing habitat for insects and other small creatures.

The installation process involves laying precast concrete modules or casting concrete in situ with specific void patterns. The voids are then filled with a suitable growing medium and seeded or planted. Maintenance typically involves regular mowing and watering, similar to that of a lawn, and occasional replenishment of soil if needed. Grasscrete is used in a variety of applications, including parking lots, pathways, driveways, and overflow parking areas.
