Sandbettlose Verlegung von PE-Rohren - Eine Frage der Rohrqualität
Over the past 30 years, the long-term strength behavior of polyethylene has improved due to advancements in raw material development. This raises the critical question of whether underground polyethylene pipes still require sand bedding. Current studies aim to determine the minimum quality level that allows for the elimination of sand bedding; some pipe qualities available on the market already meet this standard.
