Avoiding costly waterproof failures

Learn how hiring a consultant can help avoid future headaches and save money.

Outdoor balconies, plazas or roof decks that lack effective waterproofing systems can quickly deteriorate, especially in areas with heavy rainfall. This deterioration often results in costly repairs or replacements of these structures. This is why it is important to select a good waterproof membrane and have a skilled team install it, either when the structure is built or even down the line to prevent further damage. The Pli-Dek experts recommend working with a professional consultant, as they can ensure that the waterproofing system is not only one of quality, but one that is right for the situation. They also can help ensure that it is applied correctly, guaranteeing long-term durability and effectiveness. 

Defining a waterproof consultant 

Waterproofing consultants are certified professionals who have successfully passed the General Consultant Knowledge (GCK) exams, establishing their expertise in the field. Those with credentials as Registered Roof Consultants (RRC®) or Registered Exterior Wall Consultants (REWC®) are equally qualified, specializing in comprehensive building envelope solutions. 

These consultants are also required to complete 70 hours of continuing education each year and participate in industry-related seminars. Their dedication to continuous learning keeps them up to date with the latest technologies, techniques and industry standards. 

Surveying decks and roofs 

Waterproofing consultants start by conducting a detailed inspection of decks and roofs to evaluate their condition. This critical step helps uncover hidden damage that contractors may miss. Without this thorough assessment, waterproofing could be applied to a compromised surface, resulting in early failures. 

Consultants are skilled at detecting signs of rot, deterioration and other structural issues that may not be readily apparent. For concrete decks especially, underlying problems can go unnoticed without expert evaluation. 

Moisture assessments 

A key responsibility of waterproofing consultants is to assess moisture levels without damaging existing deck materials. Trapped moisture beneath plywood or concrete can lead to cracks and peeling in coatings, which compromises the waterproofing system. By using advanced techniques, consultants can detect moisture, ensuring that the surface is dry and stable before applying any waterproofing. 

Specialized testing for accurate assessment 

Consultants use a variety of specialized tests to accurately assess the condition of the deck. These tests include: 

• Infrared thermography: Measures surface temperature to identify potential problem areas. 
• Wind uplift tests: Evaluates how well the waterproofing system can withstand high wind conditions. 
• Bonded pull tests: Determines the bond strength between the waterproofing compound and the deck surface. 

In some cases, advanced testing methods like nuclear penetration testing may be utilized for deeper analysis of the deck's integrity. 

Collaboration with architects on deck design 

Consultants collaborate closely with architects and contractors to understand the specific design of the deck — whether it's a roof deck, balcony or another type. They assess drainage systems, door sills, slab conditions and railing placements to ensure the waterproofing system is applied correctly. 

Proper drainage is a crucial part of any waterproofing system. Consultants inspect the drainage setup to confirm it works effectively, helping to prevent future water damage. 

Ensuring quality control 

Quality control is a vital aspect of the consultant’s role. They oversee factors like the mixing of waterproofing compounds, deck surface cleanliness and environmental conditions during application. Monitoring these elements is essential to ensuring the waterproofing system's long-term success and durability.
