One of the most reliable methods for tile waterproofing is the application of waterproofing membranes. These membranes can be liquid-applied or sheet-based and are installed beneath the tiles. They create a continuous, impermeable barrier that blocks water from reaching the substrate. Liquid membranes are particularly useful for areas with complex shapes, as they can easily cover corners and curves. Sheet membranes, on the other hand, offer a durable and consistent layer that is ideal for large, flat surfaces.
After the tiles are installed, the next step is to protect the grout lines, which are the most vulnerable areas for water penetration. Applying a high-quality grout sealer ensures that the grout remains water-resistant and prevents water from seeping through the joints. It is essential to choose a sealer compatible with the type of grout and tiles used to maintain the effectiveness of the waterproofing.
