  • Patio/floor assembly
    Patent number: 5666772
    Abstract: A patio/floor assembly comprising interlocking plastic blocks with open drainage spaces which form a base for porous indoor/outdoor carpeting is disclosed. The carpet assembly allows the drainage of water through the carpet and plastic blocks and away from bottom of the patio/floor assembly. This avoids a build up of minerals on the substrate concrete of patios, decks, and balconies and avoids cracking of the concrete or damage to the permanent deck.
