HDB bathroom upgrades: Preventing water leakage during renovations

Begin with a thorough inspection of existing plumbing and waterproofing. Identify vulnerable areas like pipe joints and floor-wall junctions.

Waterproofing protects the structure from water damage, preventing leaks that can affect neighboring units and compromise the buildings integrity.

Cementitious or polyurethane-based membranes are commonly recommended for their durability and effectiveness in preventing water penetration.

Apply the membrane in multiple layers, ensuring full coverage of the floor and walls, particularly in wet areas like the shower and toilet.

Use specialized collars or sealants around pipes and drains to create a watertight seal and prevent water from seeping through gaps.

Conduct a water ponding test by blocking the drain and filling the bathroom floor with water for 24-48 hours to check for leaks in adjacent areas.

Experienced professionals ensure proper waterproofing techniques are employed, minimizing the risk of future water leakage and costly repairs.
