Practical Application

Professional Welding of Roofing Membranes

With the Sievert - PRO 88 Torch-On Burner Set HBS 2960, you work exactly as required in modern roofing: You heat the underside of the membrane in a controlled manner, guide the flame evenly along the seam, and create a secure bitumen melt bead. This achieves tight transitions, clean joints, and reliable adhesion – especially for bituminous waterproofing on flat roofs (e.g., connections, valleys, edge areas, and detail points).

Heating work & detail sealing

In addition to welding, the set is also suitable for heating work on substrates, for preparing bitumen surfaces, and for precise detailed work where you need stable flame guidance and a secure stand (support foot included). Practical tip: Work calmly, maintain a constant distance, and observe the material approvals of the membrane manufacturer.
