Case Studies

4D High Serviceability Slab/s / CombiSlab / Flooring / Jointless (renovation) Floors

Car park topping slab

This basement car park required a thin layer unbonded topping to remediate over a cracked and damaged slab. Unbonded toppings are inherently difficult to detail; there is a risk of reflective cracking from defects and joints from the slab below and in this case there were lots of re-entrant corners and drains. They typically require lots of joints that would require ongoing maintenance.

The Dramix® 4D CombiSlab solution enabled the construction of this joint free 100mm thick topping layer.

Technical solution:

  • Fibre type: DRAMIX® 4D 65/60BG
  • Additional Reinforcement - top layer of light mesh
  • Constructed with no moving joints
  • C30/37 concrete

Benefits

  • Slab reduction for the same capacity
  • Large saw cut free slabs
  • Reduced long term maintenance
  • Fast construction
