START WITH THE CONDITION
A useful repair starts with understanding what has actually failed.
Protect suitable tiled balcony areas and help stop water reaching spaces below.
CareSeal reviews the visible condition, likely water path and surrounding joints before defining a scope. The objective is a practical repair—not unnecessary demolition or a one-size-fits-all treatment.
Common signs to look for
✓Staining or dampness below the balcony
✓Cracked or missing grout
✓Failed perimeter or movement joints
✓Water collecting near thresholds
✓Loose or deteriorated surface joints
✓Leak symptoms that appear after rain
WHAT CAN BE BEHIND THE PROBLEM
The visible symptom is only part of the story.
Flexible joints
Thresholds, edges, penetrations and junctions can create water-entry paths.
Water path
Poor surface condition or drainage can increase the time water sits on tiled areas.
Repair scope
Some symptoms indicate a broader waterproofing issue rather than a local joint failure.

QUESTIONS BEFORE YOU BOOK
