Abstract
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.

Claim 4
Dependent Claim
108 words
A method of installation of outdoor water permeable carpeting which comprises, (a) the laying of a sub-floor of interconnecting plastic members as described in claim 1 herein, which members form a uniform and secure substrate attachable to the railings of patios and whose upper surface is porous and will allow the installation of carpeting of permeable polyethylene or polypropylene; b securing of said carpeting to the substrate tiles and, thus, eliminating the contact of the carpeting with the concrete patio or deck surface and allowing for free flow of fluids through the carpeting and off of the deck without any trapping between the carpeting and the deck surface.
