Reinforcement for strip and trench fill foundations shall ensure the safe transfer of loads and be suitable for localised ground conditions.

Reinforcement should be:

  • appropriately sized
  • placed correctly
  • clean and free from loose rust
  • secured at laps and crossings
  • supported to ensure that they are 75mm above the base of the foundation or as indicated in the design.

If in doubt about any soft spots, the designer’s advice should be taken before placing the concrete.
