Patio stones are generally used for landscaping. However, they might have other applications.
Patio stones may be used for waterproofing ground and basements alike. Patio stones installed around a perimeter of a structure along with some gravel prevents water penetration through the soil in to the concrete retaining walls. Should there be a leak in these walls, it usually results in to water rushing in from outside. Interlocking patio stones are arranged in a way with some steepness to provide a slope for rain and gutter water to move away from the property rather than in to the basement. They are also used in gardens and backyards for flood control. Excessive rain water builds up and results in to a backyard full of muddy soil. Even passages are not spared from excess mud. Installing patio stones in these areas of the property usually results in to less water accumulation, better property outlook and increased real estate values. Patio stones alongside concrete also removed the need for lawn moving and weed removal. Some contractors even lay underlayment to prevent weeding near patio stones!
To install these stones, aggregate or gravel is spread over compacted soil. This aggregate is then covered with sand beds to provide a leveled base for patio stones. Some even prefer top soil mix for grass and ground cover as a patio base leveler. A hardware piece may also be used as an alternative patio stone leveler especially near driveway, sidewalks and stairs where chances of falling over the stone are high.
Hence, patio stones have extensive application and installation method is relatively simple. One of the issues with patio stones is that they are heavy and break easily. They may also damage regular four door vehicle. The solution to this problem is cargo vans which are readily available in many garden centers and home improvement stores.
