what is Self-Adhesive Bitumen Waterproofing Membrane Equipment

Self-Adhesive Bitumen Waterproofing Membrane Equipment refers to the specialized machinery and systems used to manufacture self-adhesive bitumen membranes—materials widely used in construction for waterproofing applications, especially on roofs, basements, and foundations.

What is a Self-Adhesive Bitumen Membrane?

It is a flexible, rubberized asphalt sheet laminated with a protective film (often polyethylene or aluminum foil), and coated on one side with a pressure-sensitive adhesive layer protected by a release film. It doesn’t require heating (torch-free), making installation safer and easier.

Components of the Equipment

Bitumen Melting and Storage System

Melts and stores asphalt/bitumen at controlled temperatures.

Includes pumps, agitators, and heating controls.

Modifier Dosing and Mixing Unit

Adds SBS, APP, or other polymer modifiers to enhance elasticity, temperature resistance, and durability.

Ensures homogeneous mixing.

Coating and Laminating Line

Coats the reinforcement material (like fiberglass or polyester) with the bitumen mixture.

Laminates with surface materials like polyethylene film or aluminum foil.

Cooling and Calendering Section

Cools the coated sheet.

Controls thickness and smooths the surface via calender rollers.

Adhesive Application Section

Applies the pressure-sensitive adhesive layer to one side.

Can include silicon release liners to protect the adhesive.

Slitting and Rewinding Station

Cuts the finished membrane into rolls of desired width and length.

Rewinds the product for packaging.

Control System

Typically PLC-based for automated temperature control, speed regulation, and quality assurance.

Applications of the Membrane

Flat and pitched roofs

Foundations and basements

Bridges and tunnels

Wet areas (bathrooms, kitchens)
