Balcony Decking

Balcony and roof decking systems allow flat roofs to be safely converted into usable outdoor living areas.

We ensure:

  • Compatibility with waterproofing layers
  • Correct drainage and load performance
  • Long-term weather resistance

Our decking installations are suitable for residential properties, apartments and commercial buildings.

Creating functional outdoor spaces

Roof terraces and balconies add valuable living space and enhance property value. Professional installation ensures these areas remain weathertight while providing safe, attractive outdoor amenities.

Design considerations:

Structural capacity – Existing structure must support additional loading from decking, pedestrians, furniture and potential snow accumulation. We assess load-bearing capacity before specifying systems.

Waterproofing integrity – Decking installation must not compromise the underlying waterproof membrane. We use systems specifically designed for roof terrace applications.

Drainage management – Adequate fall ensures water reaches outlets without ponding. Drainage layers beneath decking maintain airflow and water evacuation.

Access and maintenance – Design allows inspection and maintenance of the waterproof layer beneath without complete decking removal.

Safety compliance – Balustrades, loading limits and surface slip resistance meet building regulations and safety standards.

Decking System Types

Pedestal-supported decking – Adjustable pedestals support timber or composite boards, creating a ventilated void above the waterproof membrane. This system offers:

  • Easy maintenance access
  • Excellent drainage
  • Accommodates service routing
  • Adjustable to achieve level surfaces over slopes
  • Minimal loading on waterproof layer

Directly fixed systems – Decking boards fixed to timber framework that sits on protective layers above the membrane. Suitable for certain applications where pedestal systems are impractical.

 

Material Options

Hardwood timber – Traditional appearance with natural warmth. Hardwoods like Iroko or Cumaru offer excellent durability in exposed conditions.

Softwood timber – Cost-effective option when properly treated. Requires more maintenance than hardwoods or composites.

Composite decking – Combines timber fibres with polymers for durability without the maintenance demands of timber. Resists fading, rot and insect damage.

Porcelain paving – Non-slip, fade-resistant and extremely durable. Ideal for contemporary designs and high-traffic areas.

Rubber tiles – Excellent slip resistance and comfort underfoot. Suited to play areas or where maximum safety is required.

 

Waterproofing Beneath Decking

The underlying waterproof system requires special consideration:

  • High UV resistance (despite shading from decking)
  • Pedestrian-grade durability
  • Compatibility with protective layers
  • Root resistance where planters are installed
  • Long service life to avoid disruptive replacement

We typically specify EPDM, GRP or high-performance liquid systems for balcony and terrace applications, providing appropriate guarantees for the complete system.
