Concrete landscape curbing (or concrete landscape bordering) is an alternative to plastic or metal landscape edging made with concrete. Concrete landscape curbing has become more popular over the last decade. Concrete landscape curbing has been installed in every climate in the United States and throughout the world. It is usually installed using a specialized landscape curbing machine based on a design that originated in Australia in the 1970s. Due to the expensive and laborious installation, concrete landscape curbing is usually utilized to create a permanent border. It is not particularly useful in areas where the landscape is likely to change, for example around a non-permanent swimming pool, which won't last forever, or a pine tree, where the border would need to expand with the tree's growth. Concrete landscape curbing can be used to highlight and emphasize a flowerbed or other landscaping area. Various colors and stamps are available to achieve different looks. A lawn mower wheel can be run on the curbing, eliminating edging where a curb is installed. The concrete border is also acts as a root barrier. Because of its weight, concrete landscape curbing, unlike plastic landscape edging, does not rise due to frost. ==Paving== Concrete curbing can contain decomposed granite, pavers, brick, mulch, and other pavement and walking surfaces for paths, walkways, driveways, and other outdoor circulation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Concrete landscape curbing」の詳細全文を読む スポンサード リンク
