Positive & Negative Side Waterproofing Solutions for Long-Term Building Envelope Protection

Positive side waterproofing is the first line of defense against water intrusion—applied directly to the exterior face of a structure where moisture originates. We specialize in high-performance positive side waterproofing systems that protect foundations, walls, and slabs from rain, groundwater, and hydrostatic pressure before it ever reaches the interior.

Why Positive Side Waterproofing Matters:

• Direct Moisture Control: Stops water at its source, preventing infiltration into structural elements.
• Durable Barrier Systems: Resilient membranes and coatings withstand environmental exposure and ground movement.
• Enhanced Structural Longevity: Protects concrete and masonry from deterioration, corrosion, and freeze-thaw cycles.
• Code-Compliant & Proven: Meets industry standards for new construction and retrofit applications.
• Compatible with Drainage Systems: Integrates seamlessly with weeping tile, sump pumps, and exterior insulation.

Negative side waterproofing is applied from the interior of a structure, making it the ideal solution when exterior access is limited or not possible. This method works by sealing the inside surface to prevent water from penetrating into usable spaces, helping control moisture, reduce leaks, and protect interior finishes. It’s a practical and cost-effective option for existing buildings and repair situations.

Why Negative Side Waterproofing Matters:

• Applied from the interior when exterior access is restricted
• Helps stop active leaks and moisture intrusion
• Ideal for basements, foundations, and retrofit projects
• Cost-effective solution for existing structures
• Protects interior finishes and usable space
• Can be combined with drainage or sump systems
• Fast, minimally invasive installation
