Avoid Weight Loading Issues on Roof Terraces

Alleviate localised weight loading with our modular terrace system from Raaft.

Weight Loading

The Challenge

Unless a building has been designed to feature a roof terrace, flat roof construction may be unable to cope with the weight loading.

Large landscaping features such as planters can create heavy, localised downward pressure. Adding reinforcement below these points may not be feasible, financially or technically.

The Solution

The Raaft® terrace system mitigates localised weight loading by using a framework of loadbearing joists and support pedestals.

Our modular extruded aluminium system uses interlocking joists and bracing struts to create a strong yet lightweight platform.

Height-adjustable pedestals support, stabilise and level the platform to ensure the weight is evenly distributed for maximum support.

  • Prevent waterlogging - Rainwater retention in planter soil will considerably add to the overall weight of the system. Placed under planters, Raaft® floor structure panels are perforated to allow easy drainage that prevents waterlogging.
  • Lightweight materials - The choice of decking material can also significantly change the weight loading of your roof terrace. Raaft® porcelain decking and tiles compare favourably with the durability of wood and composite decking and the weight of natural stone and concrete products.
  • Structural assistance - With data provided by your project’s assigned structural engineer, we can help you calculate safe weight loading and distribution across your terrace.
