Welcome to the websites of the RAL-quality alliance for flexible drainage pipes (a section of Qualitätsverband Kunststofferzeugnisse e.V. – Quality alliance for plastic products).
Since all times the agricultural output has been managed and boosted by regulating the water balance of the soil. Flexible drainage pipes from PVC nowadays are dominating in the field of drainage since they displaced clay pipes in the late 1960s.
The use of PVC drainage pipes has since multiplied, as also the construction industry has recognized the various advantages of the product when it comes to drainage of municipal or privat real estate properties. An ever growing demand of drainage pipes can furthermore be seen at developing of sports fields, gardens, parks and golf courses.
