How to Improve Balcony Drainage: Best Practices and Products

Effective balcony drainage is essential to prevent water buildup, structural damage, and costly repairs. Following current guidelines like the NHBC Standards 2025, proper drainage design can ensure balconies remain safe, dry, and compliant. Here’s how to optimise your balcony drainage and why solutions like AliDrain are a smart choice.

Best Practices for Balcony Drainage

1. Encourage Effective Water Flow

Effective water flow is essential for keeping balconies safe and dry. A well-designed drainage system helps prevent water from pooling, reducing risks through enhancing safety.

2. Install Reliable, Deck-Level Drainage Solutions

Choose high-quality drainage outlets that sit flush with the decking to seamlessly collect and divert water. Systems like AliDrain integrate at deck level to capture runoff efficiently and keep the balcony surface clear of standing water.

3. Use Durable, Rust-Resistant Materials

Balconies are constantly exposed to the elements, so selecting rust-resistant materials is key. Aluminium drainage products, such as AliDrain, are built for long-term durability and require minimal maintenance, making them ideal for outdoor use.

4. Piped Drainage for Multi-Level Buildings

For multi-storey buildings, a piped drainage solution is ideal, as it carries water directly to ground level. This approach helps prevent water from spilling onto lower balconies, improving water management and safety throughout the building.

5. Consider Edge Drainage

Edge drainage can be a suitable solution if it meets specific criteria. Edge drainage allows water to flow off the balcony perimeter but must be carefully designed to prevent water from affecting lower balconies or walkways. Always consult with a professional to ensure edge drainage meets building regulations.
