The ProLogis Park logistics center in Teresin is a major goods transshipment hub and temporary storage facility located about 50 km west of Warsaw. Weak spots in the roof area were jeopardizing the flawless picking of stored products, and to prevent long-term damage, the operator, ProLogis, decided to renovate the facility using Triflex liquid polymer. Despite a previous renovation using SBS bitumen membranes, water was still penetrating the warehouse during heavy rainfall. To ensure the roof’s long-term watertightness, the rainwater gutter of the standing-seam roof—consisting of approximately 1,780 standing seams—was permanently sealed with Triflex ProDetail liquid waterproofing.
