First of all, from the perspective of preventing the spread of grass roots, the isolation belt plays a key barrier role. The part that goes deep into the ground can effectively block the grass roots from growing into the stone area, prevent the grass roots from squeezing the stone, and prevent the stone from shifting or warping due to uneven force. For example, after a period of observation after laying, it was found that in the area with the isolation belt, there was rarely any unevenness around the stone due to the arching of grass roots, which maintained the neatness of the stone boundary.
Secondly, in terms of preventing soil loss, the L-shaped structure fits tightly with the lawn and stone. When it encounters rain erosion, it can block the soil on one side of the lawn to prevent the soil from flowing into the gaps of the stone or covering the surface of the stone, which not only protects the cleanliness and beauty of the stone, but also ensures the stability of the lawn soil, so that the lawn can continue to grow healthily. According to comparative tests, the areas without isolation belts had obvious soil accumulation in the stone gaps after heavy rain, while the areas with isolation belts remained in good condition.
In addition, the wear protection of the stone edges is significant. In daily maintenance and use, such as people walking and gardening tool operation, isolation belts can avoid direct friction between lawn and stone, reducing the damage and corner loss of stone edges caused by long-term friction. Long-term observations show that the edge wear of the stone borders with isolation belts installed is much lower than that of the areas without them during several years of use.
However, its protective effect is also restricted by some factors. If the isolation belt is not installed deep enough, it may not be able to effectively prevent the growth of grass roots, causing some grass roots to still enter the stone area. Moreover, if the material strength of the isolation belt is insufficient, it may deform or break when subjected to a large external force, thus affecting its protective effect on the border.
From the perspective of aesthetic improvement, it clearly divides the boundary between lawn and stone, making the entire landscape layout more regular and orderly. Isolation belts of different colors and materials can also match the surrounding environment, play a decorative role, and enhance the visual effect of the landscape.
During long-term use, attention should also be paid to the aging of isolation belts. Over time, isolation belts of some materials may fade, become brittle, etc., which may affect their fit with the lawn and stone, thereby reducing the protective effect, so they need to be inspected and maintained regularly and replaced when necessary.
Under normal installation and use conditions, the l-shaped right angle flat edge grass stone isolation belt has a good protective effect on the lawn and stone boundary in many aspects, but attention should be paid to installation details and long-term maintenance to ensure its continued function.
