What should be applied to patches in modified bitumen membranes for adequate sealing?

When patching modified bitumen membranes, asphalt emulsion is the preferred material for adequate sealing. Asphalt emulsion is specifically formulated to bond well with existing bituminous materials, providing a seamless and durable repair. It effectively conforms to the texture of the existing membrane, promoting excellent adhesion and flexibility, which are crucial for maintaining the integrity of the roofing system.

Additionally, asphalt emulsion can help ensure that the patched areas are properly waterproofed, which is essential in protecting the underlying structures from moisture infiltration. The compatibility of asphalt emulsion with modified bitumen makes it the ideal choice for ensuring that repairs are long-lasting and effective in restoring the roof's performance.

Other materials, while potentially useful in different contexts, do not provide the same level of compatibility or effectiveness in sealing modified bitumen membranes.
