Diaplas Expansion Joint is a heavy-duty surface joint profile engineered to accommodate movement in tile installations while maintaining surface integrity and providing reliable edge protection. It features robust aluminum anchoring legs that deliver long-lasting structural support and prevent tile edge damage, even under heavy traffic conditions, and is sized to accommodate tiles of either 3/8" (10 mm) or 1/2" (12.5 mm) thickness.
The profile integrates a 7/16" (11 mm) -wide, soft thermoplastic rubber movement zone designed to absorb expansion and contraction stresses while forming a clean, functional surface between tiled sections. This synthetic rubber inlay is fully replaceable, allowing for easy maintenance and extended service life.
Ideal for high-traffic commercial applications, Diaplas Expansion Joint is particularly suited for use in airports, shopping centers, hospitals, transit hubs, industrial facilities or any environment where movement accommodation, durability, and aesthetic consistency are critical.
These features make Diaplas Expansion Joint a dependable solution for managing movement within tiled fields, delivering effective stress relief, lasting edge protection, and a clean, low-maintenance finish ideal for horizontal installations in high-traffic commercial environments.
