Why is your balcony leaking?

1. Wet weather conditions

Given the constant exposure to Sunshine Coast's harsh weather, your balcony is at a high risk of water seepage. To prevent leaks, it requires effective drainage and maximum protection from the elements.

2. Natural building movement

Buildings naturally expand and contract with settling and weather changes. This movement can lead to cracks in tiles and grout lines. When rainwater enters these gaps, it sets the stage for mold growth, further weakening the structure.
