The homeowners used a combination of three Invisible Structures products for this project: Rainstore3, Grasspave2 and Gravelpave2. The existing soil is a clay-based soil that turns to a vaseline consistency when wet. The owners used a single layer of Rainstore3 filled with sandy gravel as a base course structure to shore up the foundation of their project and instantly transform the loading capacity to exceed H20. Above the Rainstore3, they installed Gravelpave2 over the higher traffic area and Grasspave2 over the lower traffic area to replace the constantly cracking concrete and create a more park-like environment in their yard. The result is beautiful.
