If parks do not turn into swamps after heavy rainfall events, if young trees do not die of thirst although there is little unpaved surface left, if sports fields remain playable during bad weather and if greens in urban areas remain green even during persistent heat waves, this is not a coincidence. The products that are used are invisible but still work underground and make sure that the ideas and work of creators in the fields of gardening, landscaping and sports field construction survive as intended.
Trees in private and public spaces make a major contribution to the urban character. We all know their varied beneficial effects as noise reducers, climate regulators, oxygen producers and dust filters. However, trees can only fulfil these functions if their growth needs regarding water, nutrient supply, soil-air balance and climate are fulfilled permanently. Impermeable surfaces and heavy compaction of the adjacent undeveloped areas frequently lead to trees not being sufficiently supplied when they take root. There is no sufficient supply with air, water or fertiliser. We need to counter these negative influences to preserve old tree populations and support the growth of new plantings from the beginning.
Why is drainage so important for sports fields?
Wear-resistant sports fields that can be used throughout the year are a precondition for any type of sport. This renders drainage systems imperative for outdoor facilities almost all the time. By regulating the hydrologic balance, drainage contributes to the long-term preservation and usability of sports fields.
