Membrane Waterproofing

Definition

A membrane, usually made of built-up roofing or sheet material, to provide a positive waterproof floor over the substrate, which is to receive a tile installation using a wire-reinforced mortar bed.

Purpose

Membrane waterproofing is used to create a watertight barrier that prevents moisture from penetrating the substrate. This is essential in areas exposed to water, such as bathrooms, kitchens, and outdoor terraces, ensuring the longevity and durability of the tiled surface.

Examples of Use

• Bathrooms: Waterproofing shower floors and walls to prevent water damage.
• Kitchens: Protecting floors and walls from water seepage in wet areas.
• Terraces: Ensuring outdoor tiled areas are waterproof to avoid structural damage from water infiltration.

Related Terms

• Waterproof Membrane: A material used to prevent water penetration in construction.
• Substrate: The underlying surface to which tiles or other finishes are applied.
• Mortar Bed: A layer of mortar used to set tiles, often reinforced with wire for added strength.

Notes

• Proper installation of the waterproofing membrane is crucial to prevent leaks and water damage.
• Different types of waterproofing membranes are available, including liquid-applied and sheet membranes.
• Regular inspection and maintenance of waterproofed areas help ensure the integrity of the barrier.
