GrassStone 80

An environmentally-friendly and permeable paver

GrassStone 80 is an environmentally-friendly permeable paver that promotes green space and good drainage. It is ideal for driveways, green paths, walkways, and patios.

GrassStone 80 Pavers are designed to facilitate the growth of grass in paved areas. Its design encourages water to drain through the voids where vegetation grows while offering sufficient structural integrity to allow for vehicular traffic. This paving stone is also often used for erosion control.

Permeable pavers: from the roundabout to the garden path

Commonly seen in the centre of urban traffic circles or roundabouts – where they may be driven over by large trucks – GrassStone 80 Pavers are turning up in many residential landscaping designs. These permeable pavers are available in one size in natural concrete colour and can be field-cut with a diamond saw for intricate geometries.

GrassStone 80 Pavers can be used as a transitioning border along driveways or parking areas to offer more green space and drainage, while still providing a heavy-duty driving surface.

A properly-prepared base is critical when installing the larger GrassStone 80 Pavers as they are much larger than other paving stones and may fail if the foundation layers are not done according to specifications.
