Tremco CPG UK offers industry-leading solutions for mechanical movement joints (MMJs), engineered to accommodate structural movement while maintaining watertightness and durable performance. Explore the importance of MMJs in modern construction, particularly in high-traffic, large-span, or movement-prone structures such as car parks, airports, hospitals, and commercial buildings.
Mechanical movement joints (MMJs) are critical for protecting buildings against structural damage caused by thermal changes, settlement, and dynamic loads. At Tremco CPG UK, we provide market-leading expansion joint systems engineered for durability, watertightness, and compliance with UK Building Regulations.
Movement joints prevent cracking, water infiltration, and long-term damage. They ensure safety, energy efficiency, and compliance in high-traffic structures such as airports, hospitals, car parks, and commercial buildings.
Mechanical movement joints are often overlooked until damage occurs—but they are critical for the long-term health of any structure. At Tremco CPG, we are committed to providing innovative, reliable movement joint solutions that not only protect buildings from movement-related damage but also enhance energy efficiency and safety.
Why Movement Joints Matter
Building materials expand and contract with temperature changes and react to loads and settlement over time. Movement joints provide controlled movement zones to prevent structural damage, preserve finishes, and maintain the integrity of waterproofing. Properly designed and sealed movement joints are critical for:
