The Aluminium Formwork Waterstop Wall Tie (commonly known as a waterstop flat tie) is a high-tensile structural accessory engineered for concrete walls requiring maximum moisture and leak protection. This tie serves a dual purpose: it securely holds opposing wall panels at a precise distance during concrete pouring while acting as a permanent internal barrier against water migration.

Fabricated from carbon steel, it features a central square steel flange fully welded around the seam to block water capillary action, making it indispensable for water-retaining concrete structures.

Key Features:
Central Waterstop Barrier: The integrated square steel plate creates a physical obstruction within the cured concrete, extending the water path and effectively preventing water or moisture from seeping along the smooth face of the tie.

Precision Wall Thickness Control: Engineered to exact wall thickness to ensure perfectly uniform wall dimensions under the extreme lateral pressures of fresh concrete pouring and mechanical vibration.

Standard Pin-and-Wedge Compatibility: Features clean, circular punched holes at both ends, allowing rapid connection to standard aluminium formwork panels using standard pins and wedges.

Formwork Break-Off Notches: Designed with precise V-notches near the ends, allowing the protruding sections outside the concrete wall to be easily snapped off clean after the formwork is struck, leaving a flush surface ready for plastering or waterproofing.

Heavy-Duty Tensile Strength: Built from high-grade structural steel to ensure zero stretching or deformation under maximum hydrostatic pressure.

Applications:
1. Waterproof wall casting in basement structures, underground car parks and foundational retaining walls.
2. Water-retaining civil infrastructure including sewage treatment plants, swimming pools, reservoirs, and pumping stations.
3. High-rise residential and commercial monolithic concrete construction projects utilizing flat-tie aluminium formwork profiles.
