A termination bar is a strip of metal used in waterproofing systems and roofing applications to secure and seal the top of a membrane or material. It is often made of aluminum, stainless steel, or other types of corrosion-resistant metal.

In waterproofing, termination bars are commonly used in conjunction with waterproofing membranes installed on foundation walls, basements, or roofs. They serve as a mechanical fastening system, helping to secure the waterproofing membrane at its top edge, preventing it from peeling away or sagging, and ensuring a tight seal against water intrusion.

The termination bar is typically fastened to the wall or roof using screws or other fasteners at designated intervals. The top edge of the waterproofing membrane is tucked behind the bar, and the bar is secured over the membrane. A bead of waterproofing sealant is usually applied along the top edge of the bar to create a watertight seal.

Using a termination bar improves the performance and longevity of the waterproofing system, ensuring the waterproofing membrane remains firmly in place and effectively protects against water infiltration. Thus, it plays a crucial role in the overall waterproofing system.
