Screed is the shaping layer between the structural slab and the tiles. Its job is simple but critical: direct water towards outlets. When screed levels are wrong, the balcony becomes a pond—standing water, efflorescence, and slip hazards are the result.

Typical Failures:

• Incorrect or insufficient falls during construction.
• Screed breakdown from water ingress or freeze/thaw cycles.
• Uneven settlement across balcony slab.
• Shortcuts like “flat screeds” that rely on grout for drainage.

Our Process:

• Assessment & Survey
  • Use laser levels to measure existing falls.
  • Identify pooling zones, outlet blockages, and slope reversals.
• Demolition
  • Remove defective screeds back to the slab.
  • Clean and prepare the surface for reapplication.
• Reconstruction
  • Install new bonded screeds with cementitious repair mortars.
  • Form correct falls (minimum 1:100, ideally 1:80) toward drains.
  • Reinforce where necessary to resist cracking.
• Integration with Waterproofing
  • Ensure screed detailing matches the waterproofing system.
  • Seamlessly tie into thresholds, outlets, and perimeter terminations.

Why Screed Correction is Essential:

• Stops Ponding – Eliminates standing water and slip hazards.
• Protects Tiles & Finishes – Prevents efflorescence, grout degradation, and surface staining.
• Enhances Drainage Efficiency – Ensures the membrane isn’t overwhelmed by pooling water.
• Long-Term Durability – Creates the correct foundation for waterproofing and tiling.

Without corrected screeds, even the best membrane system will struggle. With them, water runs off efficiently, protecting both the structure and the finishes.
