The Ultimate Guide to Bathroom and Sunken Slab Waterproofing

A leaking bathroom is one of the most frustrating problems for Indian homeowners. It not only ruins your own walls but can also cause severe damage to the neighbor’s ceiling below you. The culprit is almost always a failed sunken slab or deteriorated tile grouting. Effective bathroom waterproofing is essential to prevent this. By addressing the root cause before the tiles are even laid, you can ensure a dry, hygienic space for years to come.

What is Sunken Slab Waterproofing? Bathrooms are constructed with a “sunken slab” (a depression in the floor) to accommodate plumbing pipes. If this area isn’t waterproofed correctly before the tiles are laid, any water from a leaking pipe will pool up and seep into the concrete.

Our 3-Step Bathroom Waterproofing Process:

1. SikaTop® Seal-107 for the Sub-Base Before laying pipes, we apply SikaTop Seal-107, a heavy-duty polymer-cement slurry, to the bare concrete. This creates an impermeable basin.

2. Injection Grouting for Existing Leaks If your bathroom is already tiled and leaking, we don’t always need to break the tiles. We use specialized injection grouting to fill structural cracks behind the tiles.

3. SikaCeram® 850 Luxury for Tile Joints Traditional white cement grout washes away with bathroom acid cleaners. We use SikaCeram 850 Luxury, a high-performance, stain-repellent epoxy grout. It creates a watertight seal between your tiles that lasts for years.
