Waterproofing a balcony or terrace is a genuinely different challenge to a standard flat roof, since the surface needs to handle regular foot traffic while staying completely watertight underneath. Here's how Back to Back Roofing Worcester approaches it.
Why Balcony and Terrace Waterproofing Is Different
Unlike a roof that's rarely walked on, a balcony or terrace needs a system specifically designed to handle regular foot traffic, furniture, and general use, while still providing complete waterproofing to whatever sits beneath it — often a room, not just open space.
What Genuinely Matters for This Application
- A system specifically rated for pedestrian use, not a standard roof membrane
- Correct fall to drain water away from the structure and any doorways
- Proper detailing around drainage outlets, upstands and door thresholds
- A durable finish that looks good as well as performing properly
Common Problems With Poorly Waterproofed Balconies
- Water penetrating through to the room below
- Wear and cracking from foot traffic on an unsuitable system
- Poor drainage leading to standing water on the surface
- Failed detailing at door thresholds allowing water ingress
How We Approach Balcony and Terrace Waterproofing
- Assess the structure and intended use. A rarely used balcony has different demands to a regularly used terrace.
- Specify an appropriately rated system. Genuinely suited to pedestrian traffic, not a repurposed roof membrane.
- Detail drainage and thresholds carefully. These are the most common sources of balcony waterproofing failure.
- Finish to a durable, presentable standard. Since these areas are often highly visible and actively used.
Benefits of Getting This Right
- Genuine peace of mind that the space below stays dry
- A durable surface that copes properly with regular use
- Protects the property from the specific risks of a walked-on waterproofed area
- A finished result that looks good, not just functional
