Protective Board

Definition

A protective board is a board or sheet of material that is installed next to a waterproofing membrane and then backfilled against, protecting the membrane from puncture or damage.

Purpose

The purpose of a protective board is to safeguard the waterproofing membrane during and after construction activities, preventing punctures and ensuring the integrity of the waterproofing system.

Examples of Use

• In foundation walls, protective boards are installed to shield the waterproofing membrane from rocks and debris during backfilling.
• Roof assemblies use protective boards to prevent damage from tools and foot traffic.
• Underground structures, such as basements and tunnels, incorporate protective boards to maintain the effectiveness of waterproofing membranes.

Related Terms

• Waterproofing Membrane: A layer applied to prevent water ingress.
• Backfilling: The process of refilling an excavation around a foundation or other structure.
• Sheathing: Boards or panels used in construction to form the surface of walls and roofs.

Notes

Choosing the right type of protective board is essential for compatibility with the waterproofing membrane and the specific conditions of the construction site.
