Introducing the WTZ 1700

The LUXSEAL WT Series WTZ-1700 & WTZK-1700 is a heavy-duty watertight expansion joint cover system engineered for outdoor and open-to-sky environments where water exposure and thermal movement are constant challenges. Combining a rugged Aluminum 6063-T5 tread plate with a high-performance EPDM rubber core, the system delivers a puncture-free integrated water barrier — reinforced by a snap-fit wing seal that waterproofs every mechanical fixing point. Purpose-built for landscapes, podiums, plazas, and parking decks, the LUXSEAL WT Series ensures complete watertight integrity, superior load resistance, and reliable movement accommodation throughout the structure's lifespan.

advanced watertight protection

featuring a factory-integrated, puncture-free rubber water barrier that seamlessly connects to adjacent waterproofing membranes, the luxseal wt delivers complete water resistance — even at mechanical fixing points. the aluminum cover plate anchors through a non-penetrating fixing channel, while a proprietary snap-fit wing seal clips over every screw to seal each anchor point. this puncture-free design eliminates leak paths, prevents water ingress, and ensures reliable, long-term protection in areas exposed to constant moisture and hydrostatic pressure.

Aesthetic Choice

The LUXSEAL WTZ-1700 , crafted entirely from sleek aluminum & flexible rubber effortlessly complements any floor finish. whether you’re working with polished concrete, rustic pavers, elegant marble, or modern tiles, this expansion joint cover seamlessly blends in, enhancing the overall aesthetic of your space. trust the WTZ-1700 to provide not only exceptional functionality but also a touch of sophistication to your project, no matter the design style.

Integrated Watertight Barrier with Snap-Fit Wing Seal Protection

Our expansion joint profile features an advanced integrated water barrier engineered to maintain complete watertight integrity-even at mechanical fixing points. While the profile is secured with screw anchors for maximum structural hold, each fixing point is fully sealed by a snap-fit wing seal that clips securely over the screw head, blocking any potential water ingress at the penetration.

Hybrid Aluminum-Rubber Watertight Expansion Joint Cover - Engineered for Puncture Resistance & Acoustic Control

A heavy-duty hybrid expansion joint cover combining a brushed aluminum tread plate with an integrated EPDM rubber core. The aluminum surface shields the rubber from punctures and heavy traffic loads, while the rubber substructure delivers full watertight sealing and acoustic sound dampening - engineered for durable, silent, and leak-free performance in high-traffic floor applications.

Puncture-Free Screw Fixing — Aluminum Anchored Without Compromising the Watertight Seal

An engineered fixing detail where the aluminum tread plate is mechanically secured to the rubber profile without penetrating the watertight barrier. The screw anchors into a dedicated channel above the sealed rubber core, ensuring the rubber membrane remains fully intact — eliminating leak paths at fixing points and preserving complete watertight integrity across the entire expansion joint system.

High-Performance Rubber Core — Engineered for Strength, Flexibility & Watertight Movement Absorption

The heart of the expansion joint system, this precision-extruded rubber profile is formulated with an optimized Shore hardness to withstand heavy compressive loads while remaining flexible enough to absorb multidirectional building movement. Its reinforced geometry delivers reliable watertight sealing, long-term elasticity, and consistent performance under dynamic stress — ensuring durable protection against water ingress, vibration, and structural shifts throughout the joint's service life.

Aluminum 6063-T5 Cover Plate — Heavy-Duty Surface Protection for the Expansion Joint System

Precision-extruded from high-grade Aluminum 6063-T5, this brushed cover plate forms the structural top layer of the expansion joint system, shielding the underlying rubber core from impact, abrasion, and heavy foot or vehicular traffic. Its excellent strength-to-weight ratio, corrosion resistance, and clean architectural finish ensure long-lasting durability and a refined aesthetic, making it ideal for commercial, industrial, and high-traffic floor applications.
