bathroom grouting

Bathrooms are among the most moisture-prone areas in any building, making them highly vulnerable to water damage, seepage, and mold growth. At Rainexa Waterproofing Solutions, we specialize in professional bathroom waterproofing services that prevent leaks, protect walls and floors, and extend the life of your structure.

With a proven track record and advanced application techniques, we provide effective, durable, and affordable waterproofing for both new and existing bathrooms.


Why Bathroom Waterproofing is Essential

Bathrooms are constantly exposed to water—from showers, taps, and drainage systems. Without proper waterproofing, water can seep through tiles, grout, and plumbing joints, leading to:

  • Damp patches on adjacent walls or ceilings

  • Fungus and mold growth

  • Paint peeling and plaster damage

  • Structural weakening of slabs and beams

  • Bad odor and unhygienic conditions

Effective bathroom waterproofing prevents all these issues, ensuring a healthier and more durable living environment.


Our Bathroom Waterproofing Process

At Rainexa, we follow a step-by-step process to ensure your bathroom remains fully waterproofed and problem-free:

1. Surface Inspection & Moisture Assessment

We inspect the bathroom area—including floors, walls, tile joints, and plumbing points—for signs of moisture damage, cracks, or poor drainage.

2. Surface Cleaning & Preparation

The surface is thoroughly cleaned and prepared by removing dust, oil, loose plaster, and any previous coatings. Cracks are filled with high-performance sealants.

3. Chemical Coating Application

We apply advanced waterproofing chemicals and membranes, such as:

  • Cementitious Waterproofing Compounds

  • Acrylic Polymer-Based Coatings

  • PU Sealants for Joints and Gaps

  • Liquid Membranes for Wet Areas

These materials are designed to form a seamless, flexible, and long-lasting waterproof barrier.

4. Tile Grouting & Joint Sealing

All tile joints, sanitary joints, and corners are treated with high-grade, waterproof grouts and sealants to prevent leakage from beneath the tiles.

5. Curing and Final Inspection

After applying the waterproofing system, the area is allowed to cure. We perform water pond testing and inspection to ensure complete sealing.
