Grasspave² Early Years
In 1982 our first grass paving system was called Ritterings and was
composed of 3" PVC white rings glued onto netting and sold in 4' x 20'
mats. It was the start-a-business-in-your-garage approach. In 1988 we began
molding 3" black recycled HDPE plastic rings and still glued them onto
netting. This roll format made installation very easy for contractors and
still is the single most distinguishing feature setting us apart from all
modular pavers.
Metric Influence
In 1991 Grassrings² (Grasspave²) was introduced as a half-meter
by half-meter square of rigid 2" black recycled HDPE plastic Grasspave²
large rolls for fast installation.
