What is Negative Waterproofing?

Welcome back to our blog series on waterproofing! In this article, we'll delve into the concept of negative waterproofing and its role in construction. Negative waterproofing, also known as interior waterproofing, focuses on managing water that has already penetrated a structure. Let's explore this method and its applications.

Negative waterproofing involves creating a barrier on the interior side of a building to control and redirect water that has seeped through the exterior surfaces. It typically utilizes waterproofing materials such as coatings, sealants, or membranes applied to the inner walls, floors, or ceilings.

While positive waterproofing prevents water from entering the structure, negative waterproofing manages the water that has already infiltrated the building envelope. It ensures that the water is collected and directed towards drainage systems or sump pumps, preventing further damage or moisture-related issues.

Negative waterproofing is commonly used in existing buildings or structures where exterior access is limited. It is particularly effective in basements, crawl spaces, or areas prone to water intrusion. By implementing negative waterproofing, you can effectively manage the impact of water infiltration and protect the interior spaces from damage.

It's worth noting that negative waterproofing is often used in conjunction with positive waterproofing for comprehensive protection against water-related issues. Consulting with our experts will help you determine the most suitable waterproofing approach for your specific construction project.
