Why Choose Balcony Drip Angle 90° Internal Corner

Use Balcony Drip Angle 90° Internal Corner for critical junctions where a factory-precise 90° internal corner is required to stop water tracking and provide a rigid substrate for membrane termination. This anodised aluminium component delivers a definitive mechanical capillary break at structural reveals, reducing reliance on brittle site-bent profiles and field mitering.

Balcony Drip Angle 90° Internal Corner Common Uses

Use this component where a balcony slab meets a vertical wall and a non-negotiable internal corner geometry is required to protect waterproofing from abrasion and ponding.

• Junctions where the balcony plane intersects a 90° internal wall reveal.
• Termination points for liquid-applied or sheet membranes that require a rigid, non-flexing substrate.
• Locations that demand a pre-fabricated drip path to prevent capillary rise behind the slab.

Where Balcony Drip Angle 90° Internal Corner Performs Best

Performs reliably on aluminium or treated steel substrates in sheltered-to-moderate weathering environments where the geometry is strictly a 90° internal corner and the surrounding assembly can be properly sealed.

Coverage, Skin Time & Cure

Yield and coverage are defined by the 155mm x 155mm pre-fabricated profile, enabling a consistent overlap at the reveal. Skin time and cure depend on the selected membrane and ambient conditions; follow the membrane manufacturer’s instructions for tooling off and trafficability.

• Leg length: 155 mm per side.
• Profile designed for a precision fit at structural junctions.
• Anodised finish requires compatible primers to achieve reliable membrane bond.

Surface Prep & Application

Prepare the substrate to maximise bond durability and long-term moisture protection.

1. Clean the joint area to remove dust, oils, and loose particles.
2. Scuff or prime the anodised aluminium to ensure compatible adhesion with the membrane system.
3. Position the corner with mechanical fixings as designed, avoiding reliance on friction fit.
4. Apply a compatible sealant at the interface between the corner and adjacent surfaces to complete the capillary break.

Best Practices for Using Balcony Drip Angle 90° Internal Corner

Integrate the corner within a sequenced waterproofing strategy that accounts for slab movement, drainage, and membrane compatibility.

• Use a compatible primer on the anodised surface before membrane application.
• Employ mechanical fixings plus a continuous sealant bead; do not rely on friction fit alone.
• Verify leg alignment with the adjoining drip angle sections to maintain consistent profile height.
• Avoid direct contact between stainless steel fixings and the aluminium in wet zones to limit galvanic risk.

Handling & Storage

Handle and store the component to protect the anodised surface and dimensional integrity.

• Wear appropriate PPE during installation; ensure ventilation when using site-applied sealants.
• Store in a dry, shaded environment to prevent surface contamination.
• Transport upright or with edge protection to avoid distortion of the 90° geometry.
• Dispose of offcuts in accordance with local regulations; aluminium scrap may be recyclable.
