Why 99% of Waterproofing Leaks Are Not About the Product

When water leaks appear in a building, the first instinct is often to blame the product or system used. But here’s the surprising truth: 99% of waterproofing leaks are not caused by the materials themselves—but by how they are applied.

This is known in the industry as the 99% Principle.

What the 99% Principle Means

Studies show that only 1% of waterproofing failures are due to defective materials or systems. The rest—an overwhelming 99%—come from human error or poor workmanship.

In other words, even the best waterproofing system in the world can fail if it’s not installed properly.

Common Causes of Leaks

Most leaks trace back to issues such as: 

✔️ Improper installation or lack of surface preparation 

✔️ Using the wrong waterproofing system for the project 

✔️ Poor detailing at joints, seams, or transitions 

✔️ Applying too little or inconsistent coverage 

✔️ Incompatible materials being used together

Why This Matters for Property Owners 99% Waterproofing Leaks are not about the Products

If you’re managing a property, this principle highlights one key point: choosing the right contractor is just as important as choosing the right waterproofing system.
