Building with Compliance, Sustainability, and Confidence — with Everdry Waterproofing Experts

The Foundation of Every Building: Protection Against Water

Water is one of the most damaging elements in construction. Without proper waterproofing, even the most well-built structure can face:

• Early material decay

• Mold and corrosion

• Structural instability

  
  

The National Building Code of the Philippines (NBCP) recognizes this threat — which is why moisture protection and weatherproofing are key parts of the Building Site Requirements under Rule VII and Section 707.

Simply put, a building cannot be durable or compliant without waterproofing.

What the National Building Code Requires The Principle of Waterproofing under the National Building Site Requirements

Under the NBCP Building Site and Structural Provisions, all structures must ensure: 

✅ Proper site drainage to prevent standing water around foundations 

✅ Weather-tight walls and roofs to protect occupants and interiors 

✅ Moisture protection systems that align with safety and performance standards

These requirements are not just technical guidelines — they are legal and environmental obligations. They ensure that buildings in the Philippines can withstand heavy rainfall, humidity, and long-term exposure to moisture.

The Principle of Waterproofing in Application

Effective waterproofing follows three main principles:

1. Prevention: Stop water entry through membranes, coatings, or sealants.

2. Protection: Maintain durability by shielding concrete, steel, and insulation from corrosion.

3. Performance: Ensure long-term effectiveness through quality materials and professional installation.

   
   

Waterproofing isn’t just applied — it’s engineered. Professionals design each system according to site conditions, wall design, and environmental exposure.

Why Waterproofing Is More Than Just a Product

It’s a system, not a simple layer. Waterproofing integrates with drainage, insulation, and the building envelope — ensuring that the entire structure performs efficiently.

In doing so, it also supports environmental sustainability:

• Prevents waste from premature repair

• Preserves energy efficiency

• Reduces water infiltration that damages natural surroundings

  
  

A compliant waterproofing system fulfills both the NBCP’s structural protection goals and green building principles.
