Membrane

Definition

A sheet material that is impervious to water or water vapor. Flat steel bar spacer in between water wall tubes.

Purpose

Membranes are used in construction to create barriers that prevent the passage of water or water vapor. They are essential for waterproofing roofs, walls, foundations, and other structural elements exposed to moisture.

Examples of Use

• Roofing: Applying membranes to flat or low-slope roofs to prevent water infiltration.
• Foundations: Installing waterproof membranes around foundations to protect against groundwater.
• Walls: Using vapor barriers in walls to control moisture and prevent mold growth.

Related Terms

• Vapor Barrier: A material that prevents the passage of water vapor through walls, floors, and ceilings.
• Waterproofing: The process of making a structure water-resistant to protect it from water damage.
• Sheet Membrane: A type of membrane supplied in rolls, used for large surface areas.

Notes

• Membranes must be properly installed and sealed to ensure their effectiveness.
• Different types of membranes are available, including bituminous, PVC, TPO, and EPDM.
• Regular inspection and maintenance help ensure the longevity and performance of membrane installations.
