Why Most Leaks Happen During Installation—Not Because of the Product

The Real Culprit Behind Most Waterproofing Failures

When water leaks appear in buildings, the finger often points straight at the waterproofing product. But here’s the truth: over 90% of waterproofing failures are caused by poor installation, not faulty materials.

This statistic—backed by industry research and years of field experience—should reshape how property owners approach waterproofing. It’s not just about choosing the right product; it’s about ensuring it’s applied correctly.

5 Common Waterproofing Installation Mistakes

1. Thin Application (Insufficient Thickness)Waterproofing membranes must be applied at the correct thickness to work. If the product is "stretched" too far, it weakens the barrier and lets water in.

2. Poor Surface PreparationA dirty, dusty, or uneven surface prevents adhesion. Think of painting on a greasy wall—the result won’t last. Grinding, cleaning, and priming are essential steps that can’t be skipped.

3. Applying on Uncured ConcreteNew concrete still releases moisture and chemicals. Applying waterproofing too soon causes blistering and poor bonding.

4. Neglecting Critical DetailsCorners, drains, pipe penetrations—these are high-risk zones. Without reinforcement like fabric, fillets, or sealant transitions, they’re almost guaranteed to fail.

5. Bad Timing or Weather ConditionsWaterproofing during rain, extreme heat, or high humidity can disrupt the curing process—leading to early failures.

What Property Owners Can Do Differently

You don’t have to be a contractor to make sure things are done right. Here's how to stay proactive:

• ✅ Ask about surface preparation—not just the product.

• ✅ Verify coverage rates—request records showing the applied thickness (in kg/m² or mils).

• ✅ Check the timing—ensure curing periods are respected.

• ✅ Inspect critical points—especially corners, drains, and pipe entries.

• ✅ Request quality assurance tests—like flood tests or electronic leak detection.

Why This Matters

Leaks don’t just damage property—they drain budgets, delay tenants, and hurt reputations.
