Redefining the construction industry with innovative solutions, cuttin-edge technology and sustainable practices
Wet areas such as bathrooms, showers, kitchens, laundries, and balconies are the most common source of internal water leaks in buildings if not waterproofed correctly. Continuous exposure to water, steam, and cleaning chemicals can easily penetrate porous grout, tile adhesives, and minor cracks in the substrate. This hidden moisture migration leads to serious problems, including unsightly mold and mildew growth (a health hazard), efflorescence, detachment of tiles, decay of underlying structures (wood or concrete), and damage to adjacent rooms or properties below.
Master Proof provides comprehensive and meticulous wet area waterproofing services for residential apartments, villas, hotels, spas, and commercial facilities across Dubai and the UAE. We utilize advanced liquid-applied membrane systems to create a seamless, flexible, and completely impervious barrier beneath the final finishes (tiles, stone, etc.), ensuring long-term protection and preventing costly future repairs.
Investing in professional wet area waterproofing during construction or renovation is one of the most critical steps to protect your property's value and ensure a healthy living environment.
In Dubai's multi-story residential towers and densely built villa communities, leaks originating from bathrooms or balconies can rapidly cause damage to multiple properties, leading to complex disputes and high remediation costs. Dubai Municipality regulations often mandate specific waterproofing standards for wet areas. Master Proof ensures all applications meet or exceed these local requirements, providing compliant and reliable solutions.
Precision is key in wet area waterproofing. Our process begins with rigorous substrate preparation: ensuring the surface is clean, dry, stable, and free from contaminants. Any cracks or defects are repaired. Critical junctions, such as wall-to-floor connections and corners, are reinforced using specialized tapes or sealants. Around penetrations like drains, pipes, and fixtures, careful detailing is performed to ensure a watertight seal. We then apply the selected high-quality liquid waterproofing membrane (typically advanced polymer-modified cementitious systems or flexible polyurethane coatings) in multiple coats to achieve the required thickness, ensuring complete, seamless coverage of floors and walls up to the specified height. Proper curing time is allowed before a final inspection and handover for tiling.
Typically, the entire floor of the bathroom and shower area needs waterproofing. Shower walls should be waterproofed up to a certain height (usually around 1.8-2.0 meters), and potentially other 'splash zone' walls. Specific requirements may vary based on local codes.
Generally, no. For effective and guaranteed waterproofing, the membrane must be applied directly to the substrate *beneath* the tiles. Applying sealers over tiles is usually only a temporary, unreliable fix. Remedial work typically requires tile removal.
Both polymer-modified cementitious membranes and liquid polyurethane (PU) membranes are commonly used and effective. Cementitious systems bond well with tile adhesives, while PU offers excellent flexibility. Master Proof selects the best option based on the specific substrate and project needs.
You need to allow sufficient curing time for both the waterproofing membrane *and* the tile adhesive and grout according to manufacturer instructions. This usually means waiting several days after tiling is complete.
