Aesthetic Choice
While engineered for high performance, the WTZ-4100 does not compromise on architectural aesthetics. Its all-metal construction is designed to provide a sleek, low-profile finish that seamlessly integrates with the surrounding floor materials. This refined look ensures the joint cover, essential for structural integrity, maintains a visually appealing environment without drawing undue attention, balancing heavy-duty function with a clean, modern design.



Unique Snap-Fit Design
Engineered for excellence, this design ensures the continuous water barrier passes through the entire profile without punctures, preserving its integrity. The innovative snap-fit fixtures securely hold the profile in place, providing precision alignment and lasting performance.
Integrated, Puncture-Free Water Barrier
A unique, puncture-free water barrier is integrated into the profile, ensuring watertight integrity while simplifying installation. The barrier is constructed from durable EPDM or TPV, with high tensile and puncture resistance, securing water protection over the system’s lifespan.
Seamless Water Barrier Integration
This allows floor waterproofing to seamlessly merge with a continuous water barrier, ensuring a 100% watertight membrane. Designed for ultimate reliability, it eliminates leakage risks, delivering unmatched protection and durability for expansion joint systems.
Flush Mount
The WTZ-4100 installs at the Finished Floor Level, eliminating raised obstructions and providing a smooth, seamless transition across the joint gap. This feature enhances safety and comfort for both pedestrian and vehicular traffic.
