Positive Waterproofing vs. Negative Waterproofing

In this article, we'll compare positive waterproofing and negative waterproofing, two distinct methods employed in construction to tackle water-related issues. Let's explore the differences and advantages of each approach.

Positive Waterproofing:

Location: Involves applying waterproofing barriers on the exterior surfaces of a building.

Objective: It aims to prevent water from entering the structure by deflecting it away from the building envelope.

Benefits: Offers proactive protection against water intrusion, reduces the risk of leaks and structural damage, and is suitable for new construction projects.

Negative Waterproofing:

Location: Negative waterproofing focuses on creating a barrier on the interior side of the building.

Objective: It manages water that has already infiltrated the structure by collecting and directing it towards drainage systems or sump pumps.

Benefits: Negative waterproofing effectively controls water that has penetrated the building, helps prevent moisture-related issues, and is often used in existing structures or areas with limited exterior access.

While both positive and negative waterproofing methods have their advantages, their suitability depends on the specific requirements of the construction project. In many cases, a combination of both methods may be employed to provide comprehensive protection against water-related problems.

Consulting with our experts will help you determine the most appropriate waterproofing solution based on your project's needs, whether it's positive, negative, or a combination of both methods.
