Movement Joints

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 essential components in modern construction, designed to accommodate the natural movement of buildings caused by thermal changes, structural settlement, and dynamic loads.

Without effective movement joints, structures are vulnerable to cracking, water infiltration, and long-term structural damage. Tremco CPG UK offers a market-leading range of MMJ solutions, including the versatile VEDA® expansion joint systems and the innovative Willseal® pre-compressed sealants.

Our Range of Movement Joints 

VEDA® Expansion Joint SystemsWillseal® Pre-Compressed Sealants
VEDA provides robust mechanical joint covers and profiles engineered to manage significant structural movement across floors, walls, ceilings, and façades. Designed for durability and aesthetic flexibility, VEDA joints are ideal for commercial buildings, hospitals, transport hubs, and large infrastructure projects.

Willseal offers a range of pre-compressed foam sealants that expand to fill joints upon installation, delivering excellent air and water tightness. Perfect for perimeter joints, façade interfaces, and curtain wall applications, Willseal complements the VEDA range by sealing gaps where flexibility and airtightness are paramount.


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:

  • Protecting structural integrity
  • Complying with UK Building Regulations
  • Enhancing the longevity and safety of the building envelope
