Waterproof Membrane

Definition

A Waterproof Membrane is a membrane, which can be made of built-up roofing or an elastomeric sheet, used to provide positive waterproofing for a floor or wall.

Purpose

The purpose of a waterproof membrane is to prevent water penetration in structures, protecting against leaks and moisture damage. It ensures the longevity and integrity of building elements exposed to water.

Examples of Use

• Basements: Membranes applied to walls and floors to prevent water seepage.
• Roofing Systems: Installed under roofing materials to create a watertight barrier.
• Bathrooms: Used in shower enclosures and wet areas to prevent water damage.

Related Terms

• Built-Up Roofing (BUR): A type of roof covering consisting of multiple layers of bitumen and reinforcing fabrics.
• Elastomeric Sheet: A flexible, rubber-like membrane used for waterproofing.
• Moisture Barrier: A layer designed to resist moisture penetration.

Notes

Proper installation of waterproof membranes is crucial for effectiveness. Seams, edges, and penetrations must be meticulously sealed to ensure complete waterproofing.
