Drainage is the unsung hero of balcony performance. Even the best membranes fail if water cannot escape efficiently. Inadequate drains or poorly executed thresholds often cause water to backflow into internal living areas — leading to mould, flooring damage, and insurance battles.

Typical Failures:

• Undersized or blocked balcony outlets.
• Missing secondary overflow provisions.
• Poorly detailed door thresholds that allow backflow.
• Lack of continuous drainage at long thresholds.

Our Process:

• Assessment
  • Audit balcony outlets for compliance with current standards.
  • Test thresholds and simulate storm events to detect weak points.
• Upgrades
  • Install new strip drains, point drains, or channel systems.
  • Reconfigure falls to ensure positive flow toward outlets.
  • Provide secondary overflow points where required.
• Threshold Detailing
  • Rebuild door thresholds with step-downs or waterproof upturns.
  • Integrate membranes, drainage, and screeds for a watertight seal.

Why Drainage Upgrades Are Essential:

• Prevents Internal Leaks – Stops water entry into living areas.
• Extends Waterproofing Life – Reduces standing water pressure on membranes.
• Boosts Compliance – Ensures balcony drainage meets code and insurance expectations.
• Protects Property Value – Avoids costly flooring and plasterboard damage.

Good drainage is not optional — it’s the final line of defence against water damage.
