Think about what the patio will be used for and who will use it when looking at materials. Flat, smooth, even surfaces are necessary for dining areas, living rooms, and for accessibility. Rough cobblestones and bumpy aggregate concrete pavers could cause someone to trip or impede the mobility of a person who uses a cane, walker, or wheelchair. Conversely, ultra- smooth surfaces like concrete or polished granite can become slippery when wet. Apply slip-resistant coatings to high-traffic surfaces that have the potential for becoming slick.
